Blewit
Blewit refers to two closely-related species of edible agarics in the genus Clitocybe, the wood blewit (Clitocybe nuda) and the field blewit (Clitocybe saeva). Both species are treated by some authorities as belonging to the genus Lepista. Additional recommended knowledge
ClassificationBoth species have been treated by many authorities as belonging to the Clitocybe segregate genus Lepista. Recent molecular research suggests the genus Lepista is nested within Clitocybe.[1]. EdibilityBoth wood blewits and field blewits are generally regarded as 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 trehalose, which is edible for most people. Field blewits are often infested with fly larvae and don't store very well; they should therefore be used soon after picking. Wood blewitThe wood blewit (Clitocybe nuda = Lepista nuda = Tricholoma nudum), is an edible mushroom, found in both coniferous and deciduous woodlands. It is especially common where there is a large amount of duff built up on the forest floor. It is a fairly distinctive mushroom which is widely eaten, though there is some caution about edibility. Nevertheless it has been cultivated in Britain, Holland and France.[2] DescriptionThis 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.[3] Wood blewits can be confused with certain purple Cortinarius species, many of which may be poisonous. Wood blewits can be easily distinguished by their odor, as well as by their spore print. Wood blewits have a light (white to pale pink) spore print; Cortinarius species produce a rusty brown spore print after several hours on white paper. Distribution and habitatThe 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. Field blewitThe field blewit (Clitocybe saeva = Lepista saeva) is a mushroom similar to the wood blewit. It is commonly found growing in open plains. DescriptionThe convex cap is light cream-brown with a smooth texture. The ringless stem is thin and has light purple-blue colour, hence an alternative name Blue-Leg. Distribution and habitatIt prefers to grow in grasslands and dirt areas across Europe.
