Crepidotus mollis

Crepidotus mollis, commonly known as the peeling oysterling, soft slipper, jelly crep, or flabby crepidotus,[1] is a species of mushroom. It's edibility is unknown,[1] but it is probably inedible and possibly poisonous.[2]

Description

The cap is 1–5 cm wide and kidney shaped.[3] The cap is white when it is young and when it gets older, it turns ochre. The flesh of the cap is white and flabby,[4] and can be broken easily. It has brown fibrils and scales which wear away, leaving a smooth surface.[3] The upper layer of the cap is elastic and can be stretched slightly at the margin.[5] The gills are pale brown and soft.[6] The spores are elliptical and smooth,[7] producing a brown spore print.[6] The stalk is rudimentary or lacking.[5] Crepidotus crocophyllus looks similar to this species[4] and is sometimes confused with it.[7] The species resemble a globe in moist weather.[8] The species has a relative large size compared to other species in the genus Crepidotus.[9] The fungus Hypomyces tremellicola is a parasite that deforms this species' cap.[10]

The species is reportedly inedible,[11] and too small to consider worthwhile.[7] Since very little is known about the edibility of the mushrooms in the genus Crepidotus, none should be eaten.[12]

Similar species

Similar species include Crepidotus applanatus, C. crocophyllus, and Pleurotus ostreatus.[3]

Habitat

The species grows in groups or overlapping tiers on hardwood.[4] The hardwood includes tree trunks, fallen branches, and sawdust. Rarely, the species grows on coniferous trees.[12] The species is widely distributed and very common.[4] The months that the species can commonly be found in are from July to September.[13] The species can be found in temperate zones of North America, South America, and The British Isles. It can also be found in Europe during spring, summer, and autumn.[14]
