Galerina venenata (Deadly Lawn Galerina)

Description: Small mushroom with moist, reddish-brown cap, fading to buff; in lawns.

Cap: 3/8-1 3/8" (1-3.5 cm) wide; convex, becoming flat or with depressed center and somewhat torn, arched margin; moist, smooth; reddish- to cinnamon-brown, fading to dingy yellowish-white or pinkish-buff. Flesh moderately thick. Odor mealy; taste bitterish.

Gills: attached, nearly distant, broad; yellowish-brown, becoming cinnamon-brown.

Stalk: 1 1/4-1 5/8" (3-4 cm) long, 1/8-1/4" (3-5 mm) thick, enlarging somewhat toward base; brownish, smooth, with cottony, white mycelium about base.

Veil: partial veil leaving a small, thin ring pressed against upper stalk.

Spores: 8-11 X 5-6.5 m; oval, roughened with smooth, pool-like depression at base. Spore print rust.

Edibility: Deadly.

Season: November-January.

Habitat: In lawns.

Range: Washington and Oregon.

Look-alikes: G. autumnalis and G. marginata, both deadly, grow on decaying wood.

Comments: This species usually grows in lawns, but it may also occur on buried decomposed wood. It has reportedly caused life-threatening poisoning similar to that caused by the Deadly Galerina (G. autumnalis) and the destroying angels.
