Coprinellus subpurpureus is a species of mushroom in the Psathyrellaceae family. The species was originally found in 1948 in Cheboygan County, Michigan, USA, and described by mycologist Alexander H. Smith, who named it Coprinus subpurpureus. It was later transferred to the genus Coprinellus in 2001.^[1]

Description

The cap is 1.5 centimetres (0.59 in) tall, and up to 3.5 centimetres (1.4 in) when fully expanded. The cap surface when young has a powdery bloom (pruinose), but becomes smooth (glabrous) in maturity; it is typically brownish in color, but in maturity is colored more purple near the center, and is dark gray to black near the edges. The flesh is thin and fragile, with no discernable odor or taste. The gills have an adnate attachment to the stem, and are narrow and placed closely together; they are buff in color before darkening to black in maturity prior to dissolving (deliquescing). The stem is 4 to 10 centimetres (1.6 to 3.9 in) tall by 0.1 to 0.25 centimetre (0.039 to 0.098 in) thick.^[2]

Microscopic features

The spores are smooth, elliptical or roughly oval depending on the direction in which they are viewed, and have dimensions of 12–14 by 5.5–6.8 by 7–8 µm. The basidia are 4-spored, and 18–30 by 6–7 µm.^[2]

Habitat

C. subpurpureus was found growing on wet leaves under hardwood trees in Michigan, USA.^[2]
