Abstract :

This study was conducted on the diversity and seasonal distribution of wild mushrooms at ENPOST forest, Ilesa, Osun State, southwest Nigeria. Mushrooms found growing in the lignocolous and terrestrial habitats of the forest were collected, identified and enumerated 2 to 3 times on a weekly basis for a period of 13 months (March 2014 to March 2015), combining both rainy and dry seasons. A total of 152 mushroom species belonging to divisions Basidiomycota (146) and Ascomycota (8) were obtained during the sampling regime. The highest species richness 70(16.7%) was obtained in October 2014, whereas March 2015 had the least 11 (2.6%). In the same vein, relative abundance of mushrooms found growing in the terrestrial habitat was higher in May, September and October 2014, than those in the lignocolous habitats. Hygrocybe vitellina and Schizophyllum commune predominated in the terrestrial and lignocolous habitats respectively. Species richness and evenness, expressed as Shannon-Wiener index in the lignocolous and terrestrial habitats during the rainy season were 3.912 and 3.304 respectively and found higher than the dry season (3.019 and 2.167 respectively). Correlation analysis revealed that average monthly precipitation positively correlated with the relative abundance of mushrooms in the terrestrial habitat (r=0.7018, p=0.024). All the mushroom species investigated were specific to their respective habitats. The findings of this study show the diversity of mushroom flora at ENPOST forest, Ilesa, southwest Nigeria, thereby necessitating strict and sustainable conservation measures especially for mushrooms with great economic values.
