During the rainy season, putative ectomycorrhizal fungi were observed under three species of Caesalpinioideae Afzelia africana Sm., Isoberlinia doka Craib. and Stapf. and Isoberlinia dalziellii Craib. and Stapf., one species of Dipterocarpaceae Monotes kerstingii Gilg. and two species of Euphorbiaceae Uapaca guineensis Müll. Arg. and Uapaca somon Aub. and Lean. The fungi belong to the orders of Agaricales, Aphyllophorales, Boletales, Cantharellales, Gautieriales, Hymenogastrales, Russulales and Sclerodermatales. Some of these fungal species e.g. Lactarius gymnocarpus Heim., Cantharellus pseudofriesii Heinem., Scleroderma dictyosporum Pat., Scleroderma verrucosum Pers., Scleroderma sp2 and Russula sp1, are common to the tropical tree families known to form ectomycorrhizas. A few species of these fungi e.g. Amanita hemibapha (Berk. and Br.) Sacc., Inocybe sp1, Boletellus sp3, Lactarius sp2 and Xerocomus subspinulosus Heinem., are observed only under mycorrhizal trees belonging to the group of Caesalpinioideae legumes. However, seven fungal species Coltricia cinnamomea (Pers.) Murr., Boletellus sp5, Austrogautiera sp. (hypogeous), Lactarius sp1, Russula annulata Heim., Russula sp2 and Scleroderma sp1 seem more specific to the Uapaca species. In all, twenty-seven putative ectomycorrhizal fungi were recovered and only five fungal species were isolated from sporocarps and maintained in pure culture. Four Scleroderma species were confirmed as mycorrhizal fungi on A. africana, Isoberlinia spp. and two East African trees, Brachystegia speciformis Benth. and Afzelia quanzensis Welw. The two Uapaca species, B. speciformis and M. kerstingii possess both arbuscular mycorrhizas and ectomycorrhizas.
