General Description:

Gymnopus dryophilus is a small brown capped mushroom which is often considered to be a weed by many due to the fact that it is so common. It was formerly known as Collybia dryophila.


Diagnostic Description:

Cap: 1-7.5 cm, convex with an incurved margin when young, becoming broadly convex to flat; moist; smooth; dark reddish brown to brown when young, becoming tan to orangish brown to very pale.
Gills: Attached to the stem or free from it; whitish to pinkish, becoming buff; crowded.
Stem: 1-10 cm long; 2-7 mm thick; equal, occasionally slightly flared to base; dry; pliant and fibrous; smooth; whitish above, light buff below, becoming darker; soon hollow; usually with thin, whitish rhizomorphs attached to the base.
Spore Print: White to creamy or pale yellowish white.

Spores: 5-6.5 × 2.5-3.5 µ, smooth, elliptical, inamyloid.
Cheilocystidia 15-50 × 2-6 µ, clavate, subclavate, cylindric, or irregular; often with lobes or coralloid projections.
Hyphae:branched and swollen, interwoven hyphae 2-13 µ wide.


Distribution:

Widely distributed in North America.


Habitat:

Saprobic; growing alone, scattered, gregariously, or loosely clustered; growing from litter or twigs, in almost any hardwood, conifer, or mixed forest ecosystem


Look Alikes:

Many of the Gymnopus and Rhodocollybia species often look like Gymnopus dryophilus at first glance. Many times microscopic studies are required to determine what the species is.


Uses:

Some studies have shown that certain chemicals formed by this fungus could be used as an anti-inflammatory agent although it is mostly just thought of as a weed.
