Distribution and habitat

Stropharia ambigua Stropharia ambigua

Stropharia ambigua appears in late fall as a solitary to scattered mushroom or in groups on rich humus, usually under conifers. It can also be found with alder and other hardwoods in the Pacific Coast. It has frequently been found in disturbed areas, such as where wood was handled. The species invade outdoor mushroom beds after wood chips have decomposed by a primary saprotroph. It favors a cold and damp environment.
