High Quality Content by WIKIPEDIA articles! Marasmius sasicola is a species of Marasmiaceae fungus known from Kanagawa Prefecture, Japan. First collected in 2000, it was described in 2002 by Haruki Takahashi. The species produces small mushrooms with white caps and very short, very thin black stems. Unlike in other, similar species, the stems enter the plant matter on which the mushroom grows. The six to eight white gills are spread out around the cap, and all of them reach the stem. The flesh has no taste or odour. Found in June, the species grows on dead Sasa leaves, from which it takes its specific epithet.
