Description of Some Macrofungi from the Niokolo-Koba National Park in Senegal

The Niokolo Koba National Park (NKNP), established in 1954 and recognized as UNESCO World Heritage and Biosphere Reserve in 1981 is the largest biodiversity sanctuary in Senegal with special ecosystems of the Sudanese bioclimatic zone, a great floristic richness of 1500 species of flowering plants and a remarkable diversity of fauna. However, no data of fungi especially macrofungal is available from NKNP. The present study aims to provide for the first time data on the taxonomic of some macrofungi occurring in the Niokolo Koba biosphere reserve. Surveys carried out at Niokolo Koba allowed to sample, describe and identify 14 species of fungi with fruibodies of ‘Parc National Niokolo Koba’. These species represent 12 genera, 7 families, 4 orders all-in the Basidiomycota. These species are: Gymnopilus sp, Hexagonia sp, Lactocollybia sp, Lentinus sp, Lenzites cf acutus, Marasmiellus setulosipes, Marasmius castaneovelutinus, Marasmius sp, Polyporus arcularius, Psathyrella atroumbonata, Psathyrella tuberculata, Pulverolepiota sp, Pterula cf brunneola, Tetrapyrgos nigripes.


Introduction
Fungi have so far been poorly studies in Senegal where they have been the subject of very limited studies [3]. Some studies have focused on arbuscular mycorrhizal fungi [13]; [24], pathogenic fungi in cultivated plants [30]. Also, some authors studied the ectomycorrhizal fungi [44]; [43]; [16] focusing mainly on their ecology and physiology with less interest on the taxonomic aspects. [25] mentioned 29 of macrofungi species including 7 that were identified only at the genus level. In the framework of a prospecting campaign on macrofungi diversity in Senegal, [27] collected nearly 300 samples of macromycetes representing 82 species, 41 genera and 23 families belonging to 13 orders, 3 subclasses of the Homobasidiomycetes class of the sub-division of Basidiomycotina. (Of the unidentified species, 4 belonging to the genera Lactocollybia, Melanoleuca, Pleurotus and Volvariella seemed to be probable new species for science, showing that the necessity to carry out more study on the mycoflora of Senegal [26]; [28]. In the peninsula of Cape Verde a near to Senegal, [29] mentioned 12 species of Agaricales in the strict sense. The Niokolo Koba National Park (NKNP) is the largest natural reserve in Senegal [17] and is one of the rare sites where large animals of the West Africa savannah still survive [4]. This park also have a great diversity of animals including 14 small mammal carnivorous documented and 73 fish species estimated [41], [5]. It also hosts more than 1500 species representing 62% of plant species documented in Senegal [1], [40]. Among these plants species are 50 woody plants mentioned [7]. Due to this rich biodiversity the park was recognized as a World Heritage Site and Biosphere Reserve by UNESCO in 1981. However, no data on fungi especially macrofungal is available from the NKNP. The present study aims to provide for the first time data on the taxonomic of some macrofungi occurring in the Niokolo-Koba biosphere reserve. The prospecting that led to the discovery of the specimens studied took place in the Niokolo Koba National Park (NKNP) located in southeastern Senegal straddling the administrative regions of Kolda, Kedougou and Tambacounda ( Figure 1). It is located at the geographical coordinate 13° 04'N and 12° 43'0 with an area of 8 282 km² (9 130 km² including the buffer zone) [32].

Description of the Study Site
The climate is Sudano-Guinean influenced by two air masses, the trade winds and the monsoon, but also by precipitation and temperature [15]. It corresponds to the tropical climate domain with a dry season in winter according to the Köppen classification [21]. Rainfall ranges between 900 and 1200 mm with a rainy season from June to October while temperatures range from 25°C in December to 33°C in May [32].
The Park's hydrographic system accounts for more than 10% of the Gambia River watershed (77000 km²), which covers nearly 200 km. Its two major tributaries are Koulountou in the west and Niokolo in the east [38].
The flora is also rich and varied. The NKNP contains 1500 species of vascular plants and is home to 80% of gallery forests and 97% of Senegal's Russian forests.
There are two main types of plant formations: savannah formations on plateaus and hills, and clear forests and gallery forests in river valleys [14].

Materials and Methods
Samples collected in the field are first numbered and tagged (harvester name, exact date and place of sampling, etc.) before being air dried for 48 hours.
Microscopic observations are made after assembling fragments in water, potassium hydroxide (5% KOH) and ammoniacal Congo (Congo Red 1% in ammonia), Melzer's reagent (chloral iodine) for evidence of amyloid or dextrinoid) or Cresyl blue.
The description of the samples takes into account the ecological and morphological characteristics (macro-and microscopic) following the protocol published by [9]. It is from all these descriptive information that an attempt was made to identify the sample by working on the available literature.
Let us note only, as general works, the fascicles of the "Flore iconographique des champignons du Congo ", of the "Flore illustrée des champignonsd'Afriquecentrale " ("A preliminary Agaric Flora of East Africa" or tropical, sometimes on world monographs (see references in the bibliography), some recent books such as the Guide of Edible Fungi of Benin [11], the Macromycetes Study of Burkina Faso: Ethnomycological and Therapeutic Approach [22] etc. also a first approach of the Macromycetes of some neighboring countries of Senegal.

List of Species of Sporophore Fungi Encountered in the Park and Their Systematic Position
Investigations in the Park allowed the identification of 14 species belonging to 12 genera and 6 families divided into 4 orders of Basidiomycota.

Descriptive Study of the Species Encountered in the PARK
This description will be in alphabetical order of genera. The sample number, the date of harvest and the ecology of the specimen will be exposed first and then follow the macromorphological and micro-morphological descriptions. A thorough discussion of each identified specimen supporting our arguments (or their limitations) ends this part. In the Key to East African Species presented by [34], no match was found. For species whose stipe does not have a ring, Pegler established the key based on the size of the spores (5-7.5) μm long. On this basis, the Senegalese species does not fall into this classification. We cannot confirm this description.
[10] studied a species of Gymnopilus from the Democratic Republic of Congo (formerly Zaire) which has the same spore size but slightly different shape with a brown-orange cap coloration in the Congolese species. Cheilocystidia do not also have the same shape. The Senegalese species is perhaps undescribed.

-Hexagonia sp
Studied specimens: National Park of Niokolo Koba, MK359 PNKK Sampling date: 22-09-08 Ecology: harvested on a piece of wood. The area is wet, light is weak and litter is plentiful.

Macro-morphological characters
The cap is hemi-circular and flattened, up to 3 cm in diameter. Dark beige to pale brown in the periphery and blackish brown towards the point of attachment, forming two clearly distinct and concentric zones, the peripheral zone being less wide. Straight margin and slightly flexuous. Radially corrugated surface.
The stipe lateral or practically nonexistent (0.3 cm long maximum). Hymenophora composed of hexagonal pores, whitish color.
Micro-morphological characters 1) Spores 5.5-8 x 7-9 μm, Q = 0.78-0.88 (very low abundance on our specimens), uniformly stained in blackish brown in Congo red and very largely rounded, without inclusion. Apiculate and individualized apicles on one of the spores observed. 2) Trama of cylindrical hyphae forming a monomitic structure, x 4 μm, 100 μm long, congophilic. 3) Pseudocystidia structures (27.5 x 5 μm), pale red in color, are found in Congo. The edge of the lamellae seems sterile. No basidium was observed there. 4) Cutis simple revetment. The hyphae are cylindrical and of the same size (x 4 μm). The specimen presented here is included in the definitions of the genus. According to [39], the sessile sporophore, the largely angular or hexagonal pores, the surface of the struvous or velvety cap, a characteristic reported as very important by [19] quoted by [39], are found in the Senegalese harvest.. No correspondence was found in the authors' descriptions for the specific determination. The genus is totally tropical where 13 species have been recorded in Africa [39].
Macro-morphological characters Miniature mushrooms small but fleshy whitish to light beige.
Cap, x 0.9 cm, circular in shape and very slightly hemispherical to spread. Margin straight and slightly toothed. Smooth surface.
Stipe, 0.8 cm, central insertion and very slightly arched beige color. Finely striped, fistulous consistency with a regular base.
Micro-morphological characters 1) Spores (6-7.63-8.5 remaining observed. This sample is easily attributable to the genus Lactocollybia, because of its remarkably developed system of hyphae and pseudocystdia with bright yellow content, very obvious under the microscope. On a macroscopic level, the smooth revetment and the collybioid port may evoke a Collybia or a Hydropus, but the white color is characteristic of various Lactocollybia. [34] mentions two species of Lactocollybia for eastern Africa: L. gracillima and L. angiospermarum Singer, a pantropical species distinguished by its distinctly larger spores (7.5-11.5 x 3.2-6 μm). [37] also describe 4 species from South Africa, with different microscopic characteristics of these crops.
In the section. Alba, grouping the species with clamps connection and with pseudocystidia [18], 14 species of tropical or Mediterranean distribution are recorded. None of these species has the association of Senegalese crop characteristics, especially the dimensions of spores and cheilocystidia. It is likely an undescribed species. Comparisons have been made with descriptions of Lactocollybia sp 1 [25] but the micromorphological descriptions do not coincide in every respect with the crop presented here. In this extremely difficult group (17 species only known for the genus), we cannot for the moment put name for this harvest. Our next harvest may allow us to better distinguish this species.
Macro-morphological characters 1) Cap circular, x 1.6-2.7 cm, more or less flattened but rather narrow central depression, blackish color, with a discreet purplish tone. Hunchback margin then straight and ciliated. Mescal surface, especially in the center of the cap which is darker, these locks gradually spacing towards the margin of the cap where they end, concentrically ciliated; however, on the larger specimen, an area near the margin joins the hair dander into a nearly continuous dark circle. 2) Hymenophora consisting of white, adnate and unequal gills (lamellae and under-lamellae). Regular edge. 3) Central and slender base, 4.3 x 0.3 cm, cylindrical, rough, attenuated tapered at the base. Non-visible ornamentation (with fines wicks?) Due to the presence of mud from the substrate. Micro-morphological characters 1) Spores broadly elliptical to cylindraceous, 8-9.5 x 4-5 μm, Q = 1.8-2, practically hyaline in Congo red, nonamyloid. Several inclusions of variable size are observed in the majority of mature spores. The apex barely visible in most spores seems to be individualized in others. 2) Skeletal hyphae with globose endings, resembling cystidia on the edge of the lamellaae. These terminations can measure between 4 and 9 μm long and 2 μm wide. 3) Basidium 20 x 7 μm, almost all immature on the specimens observed. Only one basidium with two sterigmata has been observed, suggesting that the basidia may be bisporic (no tetrasporicbasidium observed). The subhymenium is highly developed and accrescent. 4) No cystidium observed. 5) Simple and regular cut pealing in cutis with hyphae with clamp practically at all the partitions. African Lentinus have received very little study. If L. squarrosulus remains an extremely widespread species among paleo tropical species [34], it is not the same for the other species of Lentinus. The species studied here does not correspond to any description of the world monograph of [34]. It seems closer to Lentinus nigroosseus, by the abundant wicks that cover the surface of the cap, the size of the basidium and the shape of the spores but differs from it by the stocky stipe and of dimension inferior to the Senegalese harvest. Spore sizes are slightly lower in L. nigroosseus. Undoubtedly the Senegalese species belongs to the Lentinus section by the abundance of hairs on the surface of the cap, by the ciliated margin and by the presence of skeletal hyphae. It is probably an undescribed species that we cannot validate because of the insufficient maturity of the fruit. It will be necessary to try to find it in the field before considering its publication. Ecology: harvested on a tree trunk, strongly anchored and difficult to separate from the tree trunk. The tree trunk is wet and the light does not exist.
Macro-morphological characters 1) Circular and flat cap; 3-4.6 cm in diameter. Surface streaked concentrically (somewhat reminiscent of some ganodermas, seen from above), of a color ranging from beige to brown, the young margin being whitish. Straight margin and slightly flexuous. These streaks are concentric reminiscent of ganodermas. Unobserved cystidia. • Pigments present in the preparations of the hymenium. • Trichoderma cap revetment. Skeletal hyphae x 5.5 μm maximum, devoid of any noticeable difference with the hyphae of the weft. This magnificent polypore, whose hymenophora gradually grows from pure white alveolated pores, which end up being organized into a radially stretched, maze-shaped network, has been determined based on the descriptions of [39]. Our harvest is identical in all respects to those made in French Guiana. The identity is yet to be confirmed, as part of an ongoing molecular study on the genus Trametes and refined fungi.
This species has been repeatedly described as new because of the variability of the hymenophora, but the comparison of all the descriptions made refers to the same species. The typical character of this species remains the yellow to brown color of all parts of the fruit. The concentric stripes of the cap, the soft and velvety surface in the fresh state then becoming glabrous in the dry state, recall Lenzites elegans with which it is sometimes confused, which has a denser and purely white to pale cream the whole surface [39].
Geographical distribution and edibility: This species is found in Australia, Asia (common in Pakistan, the Phillipine Islands, China and southern Australia), and particularly in arid regions. Edibility unknown.  [42] monograph of the genus [42] in which 134 species of Marasmiellus were recorded under the Neotropics.
Geographical distribution: This species is found everywhere in Tanzania according to [36] where it is often found in forest (saprotroph). Macro-morphological characters Cap 0.6-1.5 cm, dark brown in color, papery, circular in shape with a broadly flexuous and straight margin. • Stipe 2 to 4 cm long, central, very slender and composed of two colors: one darker towards the base of the stipe. • Lamellae slightly yellow, not free, simple and very fine.
Micro-morphological characters 1) Unobserved spores (very rare in dry specimens of marasmus). 2) Basidia (20 x 5 μm), slightly claved and forming a regular hymenium. The sub-hymenium is developed and accrescent. This sub-hymenium rests on a trama formed of hyphae forming clamps at the level of the partitions. Dextrinoid hyphae. 3) Cheilocystidia consist of two types: some brush-shaped with several fingerings, resting directly on the subhymenium; the others (20-30 x 5-6 μm) rather slightly claved intermingled with several basidia thus making the edge fertile. Clamps can be observed on the hyphae of the trama. 4) Pleurocystidia (22 x 6 μm) also present. There are claved at the base and tapered towards the top thus forming a fingerprint. • Hymenodermal revetment, consisting of thick, double-walled, pointed elements that protrude on practically lying hyphae whose width rarely exceeds 2.5 μm. • Clamps present practically to all the partitions. In comparison with other tropical regions, tropical Africa lagged far behind in research on marasmioid fungi [2]. This author has largely contributed to the study of the genus in tropical Africa by presenting a monograph of the genus Marasmius.
The Senegalese species presented here is included in the definitions of the genus. M. castaneovelutinus belongs to the section Sicci Singer, series Spinulosi. It is characterized by a dark brown cap, tight gills, rather wide spores, welldeveloped pleurocystidia, a revetment of brush elements [2]. So many characters, with the exception of spores (unobserved), found in the Senegalese crop. The dimensions of the basidia, cheilocystidia and pleurocystidia perfectly correspond to those measured on the Senegalese species. Without a doubt, it is the same species.
Geographical distribution and edibility: this fungus is known in Sierra Leone, Uganda and probably the Democratic Republic of Congo [2] and Cameroon. Its edibility is unknown.

-Marasmius sp [sect Sicci] Studied specimens: National Park of Niokolo Koba, MK36PNKK Sampling date: 22-09-08
Ecology: this mushroom is harvested from dead wood. The litter is plentiful, the humidity is important. The area is dark.
Macro-morphological characters Cap, 0.6-3.7 cm, first hemispherical and circular then slightly spread until spread in adult individuals. Straight margin and very slightly flexing toothed. Smooth surface with a darker nipple (brownish-tinged orange color).
Other more mature claved (20 x 7 μm) observed. Mature basidia not observed on the second specimen. 3) Cheilocystidia of shape and structure in brushes with rather large elements (12-18 x 5-8 (10) μm). The brush portion is 5-8 (10) μm long, medium brownish-yellow in color. 0.5-1 μm, stiff or a little sinuous. 4) Caulocystidia also observed and cylindrical with a bifurcation at the top of the cyst. 5) Hyphae x 3-8 (10) μm, parallel or intermingled, red in the congo (distinctly congophilic), a little thicker, without embedding pigment. The clamps observed almost at all the partitions. Powdered dextrinoid revetment • Dextrinoid stipe revetment. This species is easily attributable to the genus Marasmius, Sect. Sicci, because of its collyboid shape, its small size, its membranous to slightly fleshy cap, its striated margin and its cylindrical stipe. On the microscopic level, the presence of hymenodermic brush elements confirms this sample in this section.
In Sect. Sicci, a group with hymenodermic elements in brush, 46 species belonging to tropical Africa have been listed [2]. No description, especially the microscopic elements, corresponds to the description of the Senegalese sample. On a macroscopic level, the closest species seems to be Marasmius confertus Berk. & Br. Particularly by the size of the sporophores, the radially striated margin, the orange to slightly brownish color of the cap, the smooth, glabrous stipe, initially whitish then browning. Lamellae first whitish in the young state and then yellowing with the adult blossoms [2] So many macroscopic characters found in the Senegalese species. But because of the divergence of the microscopic elements, we cannot confirm this species. It may be an undescribed species.

4) Micro-morphological characters
5) Spores (7-9 x 3-3.5 μm), Q = 2.33-2.57, hyaline and cylindrical. Apiculus well loosened. Fine inclusions are observed in the spores. 6) Basidia 13 x 6 μm, rare in the mature state (a bisporic basidium observed), rather immature basidia on our specimens. • Accessional subhymenium. 7) Matted structure with a dimitic structure, prolonged by hyphae having the value of cystidia, of more claved form towards the top of the hypha. The end of these hyphae of more or less claved form extend over a length of 60 microns with a width of between 6 and 8 microns. The species presented here does not pose a problem of determination with the description made by [39]. The only reserve we can do, the specimens described by these authors are larger than 7 cm in diameter and 8 cm for the size of the stipe. This could be explained by an insufficient maturity of the Senegalese sample. The ciliated margin, the angular pores, and radially related to the stipe are also observed. On the microscopic level the size of the spores corresponds perfectly with those of the Senegalese species. The spores are also cylindrical and smooth. Without doubt, it is the same species.
Notes: The infundibuliform shape of the cap with the ciliated margin and relatively large pores are the most remarkable features of this species [39].
Geographical distribution and edibility According to [39] this species is found throughout the tropics. It is also subtropical and in warm parts of temperate zones. In Africa the species is collected in Sierra Leone, Kenya and Tanzania. She is also present in South Africa.
Its edibility is unknown. It is also found in Benin [45].
Macro-morphological characters 1) Mushrooms living in a large colony, very common. Circular and slightly conical cap in young individuals and then slightly spread in adult specimens. Slightly flexing margin that may be slightly toothed to eroded extending towards the surface of the cap by fine scratches resembling fine cracks. The color of the cap is mostly light beige towards the margin becoming darker towards the center which ends up forming a brownish to light brown conical nipple. 2) Whitish stipe and central insertion very slightly offcenter, very fragile and cracking very quickly under the effect of the cap. The ornamentation looks smooth and the shape slightly cylindrical. 3) Gills of the same color as the cap, very uneven.
The sample presented here does not pose a problem with its determination if one refers to the descriptions of [34]: the diameter of the hat, the size of the foot, the conical and then flattened shape of the hat which forms a more colored obfuscated umbo dark than the rest of the hat. On the micromorphological level, the spores correspond in size and shape, the basidia also, the abundance of cheilocystidia on a sterile ridge, the absence of pleurocystidia, the regular hymenial pattern are all characteristics found in the Senegalese sample. Without a doubt, it is the same species.
[34] noted the presence of an appendicular veil on the margin of the hat of young individuals, which disappears at maturity. This veil has not been noticed on the Senegalese crops, all of which have mature individuals. The presence of this veil, the absence of pleurocystidia, the hymenial hyaline framework and the small spores could make Pegler think of P. candolleana (Fr.) Mayor and place him in the subgenus Hypholoma (Fr.) Sing. However, it is admitted that they are distinguished by a certain number of characters, particularly by the lack of purple coloration observed on the blades, the dark brown nipple of the hat and the small and differently shaped cheilocystidia observed.
Geographical distribution: This fungus is found in Tanzania  The macro-morphological characters described by de [11] of the species harvested in Benin coincide perfectly with the Senegalese crop. The spores also correspond in shape and size.
In the genus Psathyrella, Psathyrella tuberculata is easily recognized by its growth in Tufts on dead wood, its small size, its persistent ring and fine granular scales on the cap [11]. These observations were also made during our surveys where the fungus was still growing in clumps in a very large population. It has been harvested several times on tree trunks in senescence and rotten at least on the part where the mushroom was harvested and also on other substrates.
Psathyrella tuberculata is new to the African continent, known only from the West Indies [35]. Tropical Psathyrella studies are non-existent and the number of species is probably high (De Kessel et al., 2002).
Edibility: This fungus is consumed in Benin where the populations mainly use the young specimens in sauce preparation [11].
12 -Pterula cf. brunneola Corner, 1950 Macro-morphological characters Basidioma erect, in arbuscule up to 1.5-5 cm high. Appearance bushy, with main branches more or less vertical, fine and branched, especially towards the base which has arched branches, horizontal or ascending. The ends of the branches are thin and pointed. General color clear, oily cream with a slightly pinkish tone.
Micro-morphological characters 1) Spores 6.5-7.5 x 3.8-4.5 μm, Q = 1.66-1.71, ovoid, clear in the ammoniacal Congo, with numerous internal guttules, with rather thin walls. Apical almost null and slightly pointed. 2) Basidia 18-20 x 7-8 μm, claved to widely claved, presenting like spores many inclusions. They form a regular hymenia. 3) Cystidia 12-13 x 6-5 μm, subcylindrical, sometimes strangulated on the upper 1/3 and slightly captive at the apex. Two types of hyphae observed: a first wide of 8 microns in central position and a second very fine (4 μm wide) surrounding the first on both sides. Pterula brunneola was described by [8]; as it is presented here [8], possesses practically the same micro-morphological characters of the Senegalese sample (with the exception of cystidia that were not observed on the Corner sample). It is for this reason that it would be imprudent to conclude that there is a definite determination. The macro-morphological characters also correspond even if the diameter of the branches (1.5 to 2 mm) has not been measured on the Senegalese sample. An important ecological trait: the Senegalese specimen was collected on dead wood in the forest, that of Corner (in humus soil in the forest). But Corner does not exclude that species of the genus can also be sampling on wood.
Geographical distribution of P. brunneola type: Malaya forest Uses: no clarification has been made as to the uses. Micro-morphological characters 1) Spores (7-7,5-8,5 x 4-4,35-5) μm, Q = 1,55-1,72-1,87, ovoid, clear in congo ammoniacal red. Apicula slightly depressed on some spores but seems central in others. A big guttula is observed in the spores. Non porous spores with endospore metachromatic. 2) Basidia (18-20 x 8-9 μm), 4-sporic forming a regular hymenium and having a club-like shape. 3) Cheilocystidia, (10-15 x 6-7.5), slightly variable in shape: generally claved upwards to ventro-central on one or two cystidia with a slight depression towards the base. 4) Chained hyphae observed on the spines of the hat. • Pseudo-hymenodermal revetment with interlocking claved elements up to 30 μm long and up to 5.5 μm wide. This lepiota resembles the macro-morphological descriptions of an Echinoderma by the abundance of spines on the hat and on the base of the foot [6] but the metachromatic reaction observed on the spores literally spreads this hypothesis. This chemical reaction leads us into Leucocoprinoideae. The small leucocoprinoids according to these descriptions are Pulverolepiota [6]. However, a notorious powderiness has not been observed in the Senegalese species, which does not comfort us the attribution of this species to the genus Pulverolepiota.
The descriptions of [36] correspond to the characters of our sample, in particular by the diameter of the hat which rarely exceeds 2.5 cm, the appearance of the hat on a white background and of superficial color which turns blue, the stipe blackening towards the base, the cream color of the blades; these macro-morphological characters found in the Senegalese sample.
From the micro-morphological point of view, the descriptions of [23]; [36] show spores of particular shape, characteristic of the genus Tetrapyrgos: tetrahedral with 4 radial horns; a single spore (with the same characters) is observed on the Senegalese sample (because of the dryness of the specimens: characteristic of the marasms which lose their spores in the dry state), but the shape of basidia and their dimensions, as well as the digitalized cheilocystidia, the form of the pleurocystidia, and the nodular hyphae forming branches are all characters also observed in the Senegalese sample. Without a doubt, it is the same species.

Conclusion and Perspectives
Despite the partial nature of sampling (carried out in 2 days), the taxonomic diversity is considerable. No less than 14 species were collected divided into 12 genera, belonging to 6 families belonging to 4 orders of Basidiomycota. Only one edible species has been identified. No toxic species has been harvested. The samples are dominated by Marasmiaceae and Polyporaceae (which is normal because they are grown in the forest). All the sampling species are new to the fungal diversity of Senegal and can be, among the unidentified specimens to the specific level, are new species for science.
It will be necessary to undertake new harvesting campaigns, to strive to find mature samples of Lentinus sp finally to consider its publication as a new species.
