Gymnopilus viridans (Murrill) Hesler 363906

Gymnopilus viridans is a species of mushroom in the family Hymenogastraceae. This species is part of the large genus Gymnopilus, which contains over 200 species of fungi.

Description

Gymnopilus viridans is characterized by its distinctive greenish coloration. The cap of the mushroom is typically convex to flat, with a diameter ranging from 2 to 5 centimeters. The surface of the cap is smooth and may exhibit a slight fibrillose texture. The color of the cap can vary from greenish-yellow to greenish-brown.

The gills of Gymnopilus viridans are adnate to adnexed, closely spaced, and have a yellowish to greenish tint. The stipe is cylindrical, measuring 3 to 6 centimeters in length and 0.3 to 0.8 centimeters in thickness. It is often the same color as the cap or slightly paler.

The spore print of Gymnopilus viridans is rusty orange, a common characteristic of the Gymnopilus genus. The spores are elliptical, roughened, and measure 7-9 by 4-5 micrometers.

Habitat and Distribution

Gymnopilus viridans is typically found growing on decaying wood, particularly in temperate forest regions. It has been reported in various locations across North America, although its exact distribution is not well-documented.

Ecology

As a saprotrophic fungus, Gymnopilus viridans plays a role in the decomposition of wood, contributing to nutrient cycling within its ecosystem. It is often found in association with decaying hardwoods and coniferous trees.

Edibility

The edibility of Gymnopilus viridans is not well-established. Many species within the Gymnopilus genus contain psychoactive compounds such as psilocybin and psilocin, but it is unclear whether Gymnopilus viridans possesses these properties. As with many wild mushrooms, caution is advised, and proper identification is essential before any consumption.

Taxonomy

Gymnopilus viridans was first described by mycologist Rolf Singer in 1951. The species name "viridans" refers to its greenish coloration.
