Agaricus arorae is a moderate-sized, forest-dwelling mushroom that exhibits distinctive color changes. It fruits early in the mushroom season. Unusually within the genus Agaricus, the mushroom's cap cuticle turns yellow when exposed to a base such as potassium hydroxide or sodium hydroxide but stains red when cut.[1] In the field, it has a brownish, fibrillose/squamulose cap, which turns red when bruised. Agaricus arorae was first described from Santa Cruz County but since has been found in San Mateo and Alameda counties.[2][3][4] Agaricus arorae can be distinguished by its scales and a conspicuous stipe.[5]

Agaricus arorae was named after American mycologist and author David Arora.
