Lentinus squarrosulus (Mont.) Singer was cultivated on the sawdust of five economic tropical tree spe-cies;
Chlorophora excelsa, Celtis zenkeri, Guera cedrata, Nesogordenia papaverifera and Brachystegia, collected during
processing at the sawmill. The highest yield of fruiting bodies (16.17 ± 1.25 g) was observed on B. nigerica sawdust
supplemented with 1% CaCO3, 1% sugar and 20% wheat bran. The lowest yield (4.56 ± 1.84 g), was observed on N.
papaverifera sawdust without supple-mentation. The results of this study demonstrate that L. squarrosulus
mushroom did not show any particular trend with increase in supplementation level. The study underscores the
need for guided use of sawdust types along with the required appropriate supplements.
