Stropharia ambigua, sometimes known as the questionable Stropharia, is a saprotrophic basidiomycete fungus, one of many in the genus Stropharia.
Description
The cap is 3 to 15 cm (1.2 to 5.9 in) broad, obtuse to convex, becomes plain or uplifted in age, has a smooth surface, is slimy when moist, and yellowish. The flesh is white, thick, and soft. The gills are pale gray and gradually darkens to purplish-gray or purplish-black.[1] The gills occasionally pull away from the stipe with age.[2] The stipe is 6 to 18 cm (2.4 to 7.1 in) long and is stuffed or hollow. The veil is soft and white. The spore print is dark purplish to nearly black. The species fruits in the spring and fall.[1] It does not have a volva.[2]
Edibility
The species has been said to taste like old leaves.[3] Because of conflicting reports that they received on the edibility of this species, the authors Orson K. Miller, Jr. and Hope Miller does not recommend eating it.[4] Alexander Hanchett Smith and Nancy S. Weber said that the species is not poisonous.[1] David Arora does not recommend eating this species.[2] The authors of Poisonous plants of California said that the species is suspected of being poisonous.[5]
Distribution and habitat
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.[3] It has frequently been found in disturbed areas, such as where wood was handled.[1] The species invade outdoor mushroom beds after wood chips have decomposed by a primary saprotroph.[6] It favors a cold and damp environment.[2]
