A total of ninety-three different species of mushrooms were found in the study area. These species belong to twenty-nine different families, most species belonging to the family Agaricaceae, Lyophyllaceae, Bolbitiaceae, Pluteaceae and Polyporaceae. They are dominated by the Agaricaceae family, which has a total of 48 species; followed by Lyophyllaceae represented by 6 species. The micro-habitats of mushrooms in the study area include Wood; soil around dead Tree Stump; Waste Dump; Cow Dung; Fallow; Arable land; and 22 different living trees species. More important habitats in term of mushroom species diversity are Parkia biglobosa, Tamarindus indica, and Dead Wood. The Parkia biglobosa tree has the highest species richness (45) and species diversity (Shannon Diversity index, SDI: 3.6). Tamarindus indica was the second, having 28 species richness and 2.7 SDI. These were followed by Dead Wood where 22 different mushroom species were recorded. Also, these three habitats (Parkia biglobosa, Dead Wood and Tamarindus indica) have the highest number of mushroom species (14, 8 and 6 respectively) that were peculiar to them. Most of the other mushroom species were peculiar to only one microhabitat. Different in mushroom abundance between the Arable land (SDI =3.2) and the Fallow (SDI =3.66) was not statistically significant (P=0.40). Collectively, the indigenous trees habited more mushroom species (63) than the exotic trees (20). Also, the indigenous trees (SDI =3.828) has significantly (P=0.00) more mushroom abundance than the exotic trees (SDI =2.45). Inter-annual variation of mushroom species diversity was also observed. Human activities contribute positively to mushroom diversity in the study area by creating some unique micro-habitats that are peculiar for the growth of certain mushroom species. Therefore, for maximum conservation of mushroom diversity, extremism by which all human activities will be completely removed should be avoided.
