Gymnopus dryophilus

Description 10

The cap is 2–5 centimetres (0.79–1.97 in) in diameter, convex, and russet to ochre. The gills, which are only thinly attached to the stem, are whitish and crowded, and the spore powder is white. The bald stem is up to 8 centimetres (3.1 in) long by 4 mm in diameter.

Microscopically the spores are 6×3 µm in size and slightly tear-shaped, there are lobed club-shapedcystidia (15–50 µm × 2–6 µm), and the hyphae on the cap cuticle can also have lobes.
It is contended that G. dryophilus in fact consists of a complex of different species and that several new species (including G. brunneolus, G. earleae and G. subsulphureus) should be split off from it. However these species are not generally recognized at present.

Distribution and habitat 10

This fungus is very common in northern hemisphere temperate woodlands (so much so that it is sometimes considered a "weed" mushroom). It fruits from April to December and is often seen when there are few other fungi in evidence. Although the Greekepithetdryophilus means "lover of oak trees", it is also found with other broad-leaved trees and with conifers.

Edibility 10

Gymnopus dryophilus contains toxins which may cause severe gastrointestinal issues. However, it has been listed as edible by some sources, though not worthwhile. It is recommended not to eat the stem, which is tough.

It has been found to contain anti-inflammatorybeta-glucans.

Summary 10

Gymnopus dryophilus is a mushroom commonly found in temperate woodlands of Europe and North America. It is generally saprophytic, but occasionally also attacks living wood. It belongs to section Levipedes of the genus, being characterized by a smooth stem having no hairs at the base (in contrast to section Vestipedes). Until recently it was most frequently known as Collybia dryophila.
