Amanita longipes is a small mushroom species of the Amanita genus. It feeds on decaying leaves of some woods and can be found around the Appalachian Mountains. It is a food source for various insects.

Description

Cap

The cap is typically around 2.4–10.2 centimetres (1–4 inches) wide, is hemispheric at first then becoming broadly convex to plano-convex, occasionally also slightly depressed in center; white, pallid grayish-brown or grayish buff over disk in age, surface dull and tacky at first and becoming shiny.

Gills

The gills are usually narrowly adnate, sometimes with a decurrent line, close, whitish, becoming grayish-cream on drying, with white, floccose remnants of partial veil on edges, narrow, 4.5–11 mm (1838 in) broad, sometimes anastomosing; the short gills are truncate to rounded truncate to attenuate to attenuate in steps, plentiful, of diverse lengths, unevenly distributed.

Stem

The stem is 2.5–14.2 cm (1–5+12 in) × 0.5–2 cm (1434 in), white, and tapers upward slightly to a flaring apex. The stem is decorated with easily removed, floccose material especially in upper portion; the flesh of the stem usually does not take on a color when bruised. The flesh is white, occasionally graying in damaged areas, with a firmly stuffed central cylinder, up to 7 mm wide. The ring is fibrous-floccose and rapidly evanescent. Volval remnants are absent from the bulb and the stem base or difficult to distinguish.[1]

Toxicity

One guide lists this species' edibility as unknown but doubtful.[2] It should be avoided as many species of the genus are deadly.[3]
