Bolbitius titubans, also known as Bolbitius vitellinus, and commonly known as the sunny side up,[1][2] is a widespread species of mushroom found in North America. It grows on grass and dung.
Description
The mushroom cap is 1.5–7 centimetres (1⁄2–3 in) across,[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 stem is 3–12 cm (1–4 1⁄2 in) tall and 2–6 millimetres (1⁄8–1⁄4 in) wide,[3] whitish-yellow with a fine mealy powdering, and very delicate.[6]
The fragile and soft gills are free from the stem or narrowly attached and fade from whitish or pale yellowish to rusty cinnamon with age.[4] They produce a rusty-brown spore print.[7] The spores are brown, elliptical, and smooth.[3]
Similar species
Similar species include Bolbitius aleuriatus,[3] B. coprophilus, B. lacteus, and Conocybe apala.[7]
Habitat and distribution
The species grows on grass, woodchips, compost, and dung. It is ubiquitous in North America[7] and Europe.
Edibility
The mushroom's edibility is unknown.[3] While nonpoisonous,[8] it is too small to be worthwhile.[3]
