Amanita constricta, commonly known as the constricted grisette [1] [2] or great grey-sack ringless amanita [3] is a species of mushroom-forming fungus in the family Amanitaceae. It is edible, but it is not recommended for consumption due to confusion with poisonous species. [2]

Description

Amanita constricta has a brown cap that is about 2–6 in (5–15 cm) wide. [1] The stipe is about 3–6 in (8–15 cm) tall and about 0.4–1 in (1.0–2.5 cm) wide. [1] The mushroom has a volva that tightly attaches to the stipe. [1]

Habitat and ecology

Amanita constricta is mycorrhizal, [1] and grows under oak and Douglas fir. [3] It was originally described from California, but its range may extend up into Canada. [3]

The cap surface is sticky when moist, and characterized by white warts, which are easily detached. It is initially convex, and flattens out when mature. The flesh is white and does not change colour when cut. The gills are white and closely spaced. The stem is pale yellow, and measures 4–12 cm long by 0.5–1.9 cm thick. The partial veil that covers the young fruit body turns into the ring on the stem at maturity. The spore print is white. It resembles numerous other species.

It is characterized by bearing a large fruit body with a brown cap 5–12 cm (2.0–4.7 in) across. The cap has charcoal-grey patches, which are easily removable. The stipe is 7–18 cm (2.8–7.1 in) long, white in colour, and there is no ring on it. It is slightly tapered to the top and has irregular cottony bands girdling the base. The universal veil is grey. Spores are white, spherical in shape, non-amyloid, and measure 10.2–11.7 micrometres. The mushrooms are considered edible, but field guides typically advise caution in selecting them for consumption, due to risks of confusion with similar toxic species. A. ceciliae is found in woods throughout Europe and North America, where it fruits during summer and autumn.
