Agaricus smithianus, commonly known as the golden spruce agaricus[1] is a species of mushroom in the family Agaricaceae. It was first described in 1985 by Kerrigan as Agaricus smithii.[2]
Description
The cap of Agaricus smithianus is about 5–20 centimeters and starts out ovate before becoming convex or flat. It is golden or brown in color, with a darker disc in the center.[1] The stipe is about 5–12 tall and 2–3 centimeters wide, has a ring,[3] and is bulbous at the base. The gills are free, and start out pale, before becoming a pinkish tan color, and finally turning brown. After they turn brown, the gills darken with age. This mushroom is also reported to have an almond-like odor.[1]
Similar species
Agaricus augustus is similar in appearance, and also has an almond-like odor, but its stipe is less bulbous and the cap is scalier.[4]
Habitat and ecology
Agaricus smithianus is found under Sitka spruce[4] in conifer forests.[1] It is found in California[3] and occasionally near the coast in the Pacific Northwest.[1]
