Coprinellus subpurpureus
Encyclopedia
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.
is 1.5 centimetre (0.590551181102362 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 cm (1.6 to 3.9 in) tall by 0.1 to 0.25 cm (0.0393700787401575 to 0.0984251968503937 in) thick.
Microscopic features
The spore
s 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.

Mushroom
A mushroom is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground on soil or on its food source. The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus; hence the word "mushroom" is most often applied to those fungi that...

Psathyrellaceae
The Psathyrellaceae are a family of dark-spored agarics that generally have rather soft, fragile fruiting bodies, and are characterized by black or dark brown, rarely reddish, or even pastel colored spore prints. About 50% of the species produce fruiting bodies that dissolve into ink-like ooze...

The pileus is the technical name for the cap, or cap-like part, of a basidiocarp or ascocarp that supports a spore-bearing surface, the hymenium. The hymenium may consist of lamellae, tubes, or teeth, on the underside of the pileus...
