Agaricus smithianus, commonly known as the golden spruce agaricus[1] is a species of mushroom in the family Agaricaceae.
Taxonomy
[edit]The species was first described in 1985 by Kerrigan as Agaricus smithii.[2]
Description
[edit]The cap is about 5–20 centimetres (2–8 in) wide 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 cm (2–4+3⁄4 in) tall and 2–3 cm (3⁄4–1+1⁄4 in) wide, has a ring,[3] and is bulbous at the base. The gills are free, starting out pale, becoming pinkish tan then brown before darkening with age. The mushroom is reported to have an almond-like odor.[1]
Similar species
[edit]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
[edit]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]
