Three agricultural by-products (oil palm fruit fibre, banana leaves and sawdust) were supplemented with wheat bran, NPK fertilizer and urea at 5 - 20% (w/w) for wheat bran and 0.1, 0.5, 1.0 and 2% (w/w) for NPK and Urea. The supplemented substrates were used to cultivate Psathyrella atroumbonata. There was sporophore formation in all the substrates supplemented with NPK except at 1% and 2% in oil palm fruit fibre and 2% in banana leaves. The highest yield was on sawdust supplemented with wheat bran at 5%. Urea as supplement did not support sporophore formation in all the substrates except in sawdust but with low yield at 0.5%.

Key words: Suplementation, wheat bran, NPK, urea, sporophore Psathyrella atroumbonata.
