Diversity of saprotrophic and ectomycorrhizal mushrooms of the university campus of Lomé in Togo
Macromycetes found on woody substrate (saprotrophic and ectomycorrhizal) of the university campus of Lomé in Togo are identified according to transect-plot method. A diversity of thirty-three (33) taxa of macroscopic fungi are identified up to genus level (sixteen taxa) and up to species level for seventeen taxa (17). Identified taxa included two (2) ectomycorrhizal species (Phlebopus sudanicus and Pisolithus tinctorius) and thirty-one (31) saprotrophs. The 32 taxa belong to the subdivision of Basidiomycotina. Ganoderma genus are represented by four species belonging to the family Ganodermataceae, which colonizes the greatest number of exotic wood substrates species (17) and local species (5). Azadirachta indica is the most colonized substrate by ten species of Macromycetes, followed by Delonix regia and Senna siamea colonized by nine and seven species respectively. According to the inventoried taxa, four species (Volvariella volvacea, Psathyrella tuberculata, Macrocybe lobayensis, Leucocoprinus cretatus) are edible mushroom and three (Ganoderma lucidum, G. colossus, Daldinia eschlosii) are therapeutic mushrooms. The subdivision of Ascomycotina is represented by only one species, Daldinia eschscholzii, of the order of Xylariales. Twenty-two (22) taxa of tree species representing woody host substrates of macromycetes are identified including eighteen Angiosperms (sixteen dicotyledons, two monocotyledons) and two gymnosperms (Cycas circinalis (Cycadophyte) and Pinus caribea (Coniferophyte)). The knowledge of macromycetes in this area subjected to a perpetual anthropic pressure for the establishment of infrastructures is therefore necessary, which will make it possible to have data on the diversity of this biological heritage before their eventual disappearance.
