Abstract

 

Lentinus squarrosulus, an indigenous mushroom specie commonly found growing on dead logs in the Zaria environ of Kaduna State was cultured on six different medium which were inoculated separately with three different spawn grains and amended with six different oils at five different rates. The interaction of spawn grains x culture medium had a highly significant effect on carpophore dry weight and stipe and pileus diameters of L. squarrosulus. The results reveal that the interaction of millet spawn x animal bedding and rice medium induced the widest stipe diameter while the interaction of corn spawn x animal bedding and rice medium induced the heaviest carpophore dry weight as well as the widest pileus diameter.

 

Key words: Lentinus squarrosulus, spawn grain, carpophore production, non-composted culture medium, polypropylene heat resistant bags, flushes, stipe and pileus diameter, fruiting bodies.
