How do you identify shaggy mane?

Cap
Measures 3-15 cm. Young caps are oval or nearly cylindrical, then expand into a bell shape. The surface is whitish with a brownish center and large, shaggy scales.[1]
Gills
Very crowded and free from the stem. They change from white to pinkish and black, then liquefy as they mature.[1]
Stem
Measures 5-20 cm long and 1-2 cm thick. White, smooth and hollow, with a string-like strand of fibers inside.[1]
Ring
A ring is present on the stem.[1][5]
Flesh
White and soft.[1]
Spore print
The spore deposit is black.[1]
Cultivated form
Cultivated specimens also pass through growth, discoloration and autolysis stages: the fruiting body eventually breaks down.[13]

Can you eat shaggy mane?

Edible only when young: within hours of harvest it turns into a black liquid. Prepare it soon after picking. It can cause digestive upset when eaten with alcohol. When foraging, eat only specimens with a confirmed identification. If you suspect mushroom poisoning, contact a physician or a poison center.[4][8][9]

Its flesh is soft. It is used in mushroom soup. Microwaved and frozen, it yields a liquid that can serve as a base for risotto. Prepare it soon after picking: the black parts quickly turn bitter.[1][3][4]

Where and when does shaggy mane grow?

It decomposes organic matter. It grows on lawns, wood chips and compacted soil, alone or in groups.[1]

North American descriptions report summer and fall. The consulted sources provide Mexican records but do not establish a nationwide fruiting calendar.[1][10]

It is widely distributed in North America and documented worldwide. Mexican records include the listed entities; the list combines cited localities and is not a complete inventory.[1][10][11][14]
