Mushroom
A mushroom is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground on soil or on its food source. The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus; hence the word "mushroom" is most often applied to those fungi that...

Description
This mushroom can range from lilac to purple-pink. Some North American specimens are duller and tend toward tan, but usually have purplish tones on the stem and gills. The gills are attached to the short, stout stem. Mature specimens have a darker color and flatter cap; younger ones are lighter with more convex caps. Wood blewits have a very distinctive odor, which has been likened by one author to that of frozen orange juice.Wood blewits can be confused with certain purple Cortinarius
Cortinarius
Cortinarius is a genus of mushrooms. It is suspected to be the largest genus of agarics, containing over 2000 different species and found worldwide. A common feature among all species in the genus Cortinarius is that young specimens have a cortina between the cap and the stem, hence the name,...

Distribution and habitat
The wood blewit is found in Europe and North America and is becoming more common in Australia, where it appears to have been introduced. It is a saprotrophic species, growing on decaying leaf litter.Edibility
Wood blewits are generally regarded as a good edible, but they are known to cause allergic reactions in sensitive individuals. This is particularly likely if the mushroom is consumed raw, though allergic reactions are known even from cooked blewits. Wood blewits contain the sugar trehaloseTrehalose
Trehalose, also known as mycose or tremalose, is a natural alpha-linked disaccharide formed by an α,α-1,1-glucoside bond between two α-glucose units. In 1832, H.A.L. Wiggers discovered trehalose in an ergot of rye, and in 1859 Marcellin Berthelot isolated it from trehala manna, a substance made...

Naming
The widely used synonym Lepista nuda should no longer be used since Lepista has been synonymized with Clitocybe. The primary issue here is a debate about the correct type for the genus Clitocybe. Some, including Singer, take the type to be C. gibba. However, the majority of experts now take C. nebularis to be the type. If you take C. nebularis to be the type then Lepista becomes a deprecated synonym of Clitocybe and Clitocybe nuda is the correct name for this species.External links
