Pileus
Cap 2-6 cm broad, convex to plano-convex; surface smooth, viscid, yellowish-brown to orange-brown; margin translucent striate; flesh very thin.

Lamellae
Gills adnexed to short-decurrent, close to sub-distant, with two tiers of lamellulae; pale yellowish when young, becoming yellowish-orange to concolorous with the pileus to pale brown in age.

Stipe
Stipe 2-10 cm long, 2-6 mm thick, smooth and white to buff above the annulus, dull gray-brown and fibrillose below, mostly equal, with a prominent annulus forming a white to rusty spore coated apical ring that is sometimes missing in age.

Spores
Spores 8-11 X 5-6.5 µm, elliptical, light brown in water, non-amyloid, ornamented with low warts. Spore print rusty brown.

Habitat

Edibility
Deadly poisonous. Contains alpha-amanitins in sufficient quantities to cause death.

Comments
Galerina autumnalis and its close relatives Galerina marginata and Galerina venenata have been mistaken in the past with representatives of the genus Psilocybe by those interested in collecting hallucinogenic mushrooms. This has resulted in several poisonings and at least one death.
