Hed Khae (Lentinus sp.) is an edible wild mushroom found in local market in southern Thailand. Dikaryotic mycelium of Hed Khae was isolated into potato dextrose agar and used to study some physiological characteristic and cultivation potential. Hed Khae mycelium grew well on V-8 juice agar and potato dextrose straw extract agar. Cellulose, fructose, glucose, soluble starch and sticky rice flour were good carbon source for mycelial growth. Interm of nitrogen source, ammonium chloride, ammonium nitrate and ammonium sulfate were good nitrogen source. Light inhibited mycelial growth rate as well as fruiting body development of Hed Khae. For cultivation, the method of growing mushroom in autoclavable plastic bags was applied. Substrate used for cultivation was sawdust of para rubber logs supplemented with 3 percent rice bran, 3 percent corn meal, 1 percent soya bean meal and 1 percent Ca (OH2). The time required for spawn running was 40-45 days in 800 gm of substrate. The bags were incubated for 4 months before transferred to mushroom house. Fruitings began 25 days after watering and yield obtained was 55.5 gm/bag (B.E.=10.7 percent) in a period of two months.
