Description

The mushroom cap is between 1.5–7 cm,[2] and grows from egg-shaped when young to broadly convex, finally ending up nearly flat.[3] The cap's color starts yellow or bright yellow, and fades to whitish or greyish with age.[4] The gills are free from the stem or narrowly attached to it, are fragile and soft, and fade from whitish or pale yellowish to rusty cinnamon with age.[3] The stem is 3–12 cm tall and 2–6 mm wide,[2] is whitish-yellow with a fine mealy powdering, and is very delicate.[5] The spores are brown, elliptical, and smooth.[2]

The mushroom's edibility is unknown but it is too small to be worthwhile.[2]

A similar species is Bolbitius aleuriatus.[2]
