Bolbitius titubans, also known as Bolbitius vitellinus, and commonly known as the sunny side up[1] is a widespread species of mushroom found in America and Europe. It grows chiefly on dung or heavily fertilized soil, and sometimes on grass. It is nonpoisonous.[2]
Description
[edit]The mushroom cap is between 1.5–7 cm,[3] and grows from egg-shaped when young to broadly convex, finally ending up nearly flat.[4] The cap's color starts yellow or bright yellow, and fades to whitish or greyish with age.[5] 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.[4] The stem is 3–12 cm tall and 2–6 mm wide,[3] is whitish-yellow with a fine mealy powdering, and is very delicate.[6] The spores are brown, elliptical, and smooth.[3]
The mushroom's edibility is unknown but it is too small to be worthwhile.[3]
A similar species is Bolbitius aleuriatus.[3]
