with finger-like outgrowths, and diverticulate cap cuticle hyphae. M. granulifera differs in forming a whitish, wrinkled cap and club-shaped to roughly spindle-shaped pleurocystidia. Mycena nidificata also bears some resemblance to the European species M. flos-nivium, which is distinguished by having cylindrical, amyloid spores, gills without veins between them, and an absence of cord-like rhizomorphs. Habitat and distribution Mycena nidificata is known only from Kanagawa, Japan. The mushroom is found growing solitary or scattered, on dead fallen twigs in forests dominated by the oak species Quercus castanopsis. Fruiting occurs from May to September.
