Tsukiyotake, Moonlight Mushroom
A poisonous, bioluminescent gilled mushroom that grows on dead beech in the mountains of East Asia. In Japan it was the single most frequent cause of mushroom poisoning from 1996 to 2005 (31.6% of cases), usually after being mistaken for shiitake (Lentinula edodes), hiratake (Pleurotus ostreatus) or mukitake (Sarcomyxa edulis).
Poisonous. Contains illudin S and illudin M. Vomiting, stomach pain and diarrhea begin about 30 minutes to 1 hour after eating and last several hours; treatment is mainly fluids. Confused with shiitake, oyster mushroom (hiratake) and mukitake; check for growth on dead beech and gills that glow in the dark.
