Agaricus diminutivus, commonly known as the diminutive agaricus,[1] is a species of mushroom in the genus Agaricus. It is unique among its genus due to its small size,[1][2] and was first described in 1873.[3]
Description
The cap of Agaricus diminutivus is about 1-3 centimeters in diameter. It starts out round or ovoid, becoming convex or flat. It is pale, often being whitish or tannish.[2] The stipe is 2-6 centimeters long and 3-10 millimeters wide, with a ring around it that sometimes disappears.[1] The gills are free, and start out a pale pinkish tan color becoming pink and finally brown. The mushroom's flesh both bruises slightly yellow and turns yellow when potassium hydroxide (KOH) is applied.[2] The spore print is brown.[1]
While likely edible, this mushroom is not recommended as food because it can be confused with poisonous Inocybe species.[1][4] It is also very small and not very common.[2][3]
Agaricus diminutivus is actually a species complex, consisting of multiple closely related species that are difficult to distinguish from one another.[1][2]
Habitat and ecology
Agaricus diminutivus grows in forests, especially under conifers. It fruits during autumn.[2]
