Amanita gemmata (Gemmed Amanita)

Description: Buff-yellow cap with cream patches, ring on stalk, and basal cup attached to stalk or with small, free collar.

Cap: 1-4" (2.5-10 cm) wide; rounded, becoming convex to flat; margin radially lined; tacky when wet, smooth; pale yellow to buff, with small, irregularly placed, cream patches.

Gills: free or slightly attached, crowded, broad to narrow, white.

Stalk: 2-5" (5-12.5 cm) long, 1/4-3/4" (0.5-2 cm) thick, somewhat enlarged near oval basal bulb; slightly cottony to smooth, white or cream.

Veils: universal veil white to cream; leaving patches on cap and stalk base, or basal cup attached to stalk or with free rim at tip of bulb. Partial veil white; often leaving evanescent, pendant ring on upper stalk.

Spores: 8.7-11 X 5.5-8.5 m; broadly elliptical, smooth, colorless, nonamyloid. Spore print white.

Edibility: Possibly poisonous.

Season: June-October; November-February in California.

Habitat: On the ground, in oak and pine woods; woods and parks in urban areas.

Range: Throughout North America.

Look-alikes: A. citrina has pale greenish-yellow cap, abruptly bulbous base, and amyloid spores.

Comments: The Jonquil Amanita (A. junquillea) and Russulalike amanita (A. russuloides) may only be variants of this species. It is thought to have hybridized with the poisonous Panther (A. pantherina ) in the Northwest, producing mushrooms with characteristics of both species. The Gemmed Amanita often loses its ring and veil remnants, especially after a rain, and can then be mistaken for a Russula or Tricholoma. This mushroom is sometimes eaten; however, it may well be a species complex, and some of its forms may contain toxins, so it is best avoided.
