Coprinellus amphithallus is a species of mushroom in the Psathyrellaceae family. It was first described by mycologists M. Lange and Alexander H. Smith in 1953 before being transferred to the genus Coprinellus in 2001.^[1]

Description

The cap is 0.6 to 1.2 centimetres (0.24 to 0.47 in) tall, and initially sharply conical in shape, but later expands to become bell-shaped (campanulate). The margin of the cap curves upwards as the mushroom ages. The gills are narrow, and spaced close together. They have an adnate attachment to the stem, and become black in color before dissolving (deliquescing). The stem is 3 to 5 centimetres (1.2 to 2.0 in) by 0.08 to 0.1 centimetre (0.031 to 0.039 in) thick, hyaline to whitish. Initially it is pruinose (with a very fine whitish powder), but later becomes smooth.

The spores are cylindrical and tapering (terete), and tend to vary in size, with dimensions ranging from 11.2–15.6 by 6.2–8.3 µm. The spore-bearing cells, the basidia, are all 2-spored.

Habitat and distribution

This fungus was discovered growing in rich, moist soil. It is known from Denmark and the USA.^[2]
