“…As a result of these, the distribution and productivity of wild edible mushrooms are also affected, whose environmental requirements differ among different species (Egli, 2011;Alday et al, 2017;Vishwakarma et al, 2017). However, the magnitude by which trees in the dry lands influence the meteorological conditions at a micro-scale, under their canopy depends on their crown morphological attributes like the size, density, depth of their crowns and leaf density (Buba, 2015a;Buba, 2015b). These features should be expected to vary among different tree species and individuals.…”

Objective: The objectives of this study was to identify the various microhabitats in which edible mushrooms grow; to identify their fruiting pattern time; and to relate the findings to their optimal exploitation in a Nigerian savannah. Methodology and Results: The mushrooms were collected at the onset to the end of the rainy season. Mushrooms at different stages of growth were handpicked; photographed at different resolutions and their microhabitats and the month in which they were found was recorded. Species identification was archived by carefully examining the attributes of the sporocarps such as colour, shape, size, texture of the cap; and presence or absence of gills, etc. T-Test and Diversity Indices were conducted on the data. Thirty-one (31) different edible mushroom species were found in the study area. They largely belong to the families of Agaricaceae, Lyophyllaceae and Polyporaceae. They are found in 18 different microhabitats, which include Arable Lands; Fallow lands; soils around dead Tree Stumps; Woods; and 14 different living tree species. The highest species richness (15) and species diversity (Shannon Diversity index, SDI: 2.54) was found under Parkia biglobosa tree. The second was Tamarindus indica, having 8 species with 1.95 SDI; followed by Decaying Wood where 6 different mushroom species were recorded with SDI of 1.57. Collectively, the exotic trees habited 8 mushroom species, while the indigenous trees habited 18, which was significantly (p-value = 0.0001) different. Decaying Wood has the highest peculiar species, which was 5; Fallow have 4 species; followed by Parkia biglobosa that has 3 species. Out of the total 31 species 21 were found in the year 2016 and 24 in 2017, while only13 species were found in both 2016 and 2017, but the difference was not statistically significant (p-value = 0.961). Conclusion and Application of results: The study area is rich in diverse edible mushroom species, which comprises mostly of those species belonging to the family Agaricaceae, Lyophyllaceae and Polyporaceae. The microhabitats of these mushrooms include arable lands currently under cultivation; abandoned fallow lands; soils around dead tree stumps; decaying woods; and 14 different living tree species. The result of this study has important information that can be an indispensable guide for proper exploitation of edible mushrooms in this region and elsewhere.

We surveyed the macrofungi of an area dominated by northern Guinea savanna habitats in north‐east Nigeria. A total of 93 different species of mushrooms were found in the study area. These species belong to 29 different families, most species belonging to the family Agaricaceae, Lyophyllaceae, Bolbitiaceae, Pluteaceae and Polyporaceae. A total of 48 species belonged to the Agaricaceae, 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. The most important habitats in term of mushroom species diversity were Parkia biglobosa, Tamarindus indica and dead wood. The Parkia biglobosa tree had 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 and has of 2.1 SDI. Also, these three habitats (Parkia biglobosa, dead wood and Tamarindus indica) had the highest number of mushroom species (14, 8 and 6 respectively) that were confined to them. Most of the other mushroom species were confined to only one microhabitat. There was no statistically significant difference in mushroom abundance between arable land and fallow. Collectively, the indigenous trees were associated by more mushroom species (63) than the exotic trees (20) and the indigenous trees also had significantly higher mushroom abundance than the exotic trees. However, the non‐indegenous trees had more species forming mycorrhiza than the indegenous trees, presumaby because the former were able to form symbioses with both native fungi and introduced species from their origina habitats. 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 support the growth of certain unique mushroom species. Therefore, for maximum conservation of mushroom diversity, conservation measures excuding all human activities should be avoided.
