Description

edit

Agaricus subrutilescens has a cap that is 5–15 cm (2–6 in) across, dry, and has many wine to brown colored fibrils, especially near the center.[3] The gills are close and white at first, turning pinkish and then dark brown in age.[4] The stalk has a skirt-like ring and is 4 to 20 cm (1+58 to 7+78 in) long, 1–3 cm (381+18 in) thick, white, and covered with soft woolly scales below the ring.[3] The flesh is white and does not stain, and the odor and taste are mild.[3]

The purplish fibrous cap and shaggy white stem differentiate this mushroom from others which resemble it. Similar species include Agaricus hondensis and Agaricus moelleri.[3]

This mushroom is variously described as edible,[3] inedible,[5] or responsible for causing gastric upset.[6]

Habitat and distribution

edit

The mushroom fruits in undisturbed mixed woods in Western North America and Japan. It grows by itself or scattered in small clusters,[4] often under redwood, pine, or alder. Recently this mushroom has been identified in New Zealand and Australia.[7]
