Collybia brunneocephala is a species of mushroom belonging to the family Omphalotaceae. It is a small, brown-capped mushroom found in deciduous and coniferous forests, often growing in clusters on the decaying wood of fallen trees or stumps. This species is part of the genus Collybia, which includes mushrooms characterized by their gilled caps, central stipes (stems), and saprotrophic mode of nutrition, meaning they obtain nutrients by decomposing organic matter.

Description

Collybia brunneocephala features a cap that ranges from 2 to 4 cm in diameter, initially convex before flattening out with age, often with a slight central depression. The cap surface is smooth and brown, darkening in wet conditions. The gills are adnate to adnexed, white to light brown, and closely spaced. The stipe is slender, cylindrical, and the same color or slightly lighter than the cap. It lacks a ring. The flesh is thin and brown, with a mild taste and a faint smell.

Habitat and Distribution

Collybia brunneocephala is found in both deciduous and coniferous forests across North America and Europe. It prefers moist environments and is typically found growing in clusters on the decaying wood of fallen trees or stumps. Its fruiting season is late summer to fall.

Ecology

As a saprotroph, Collybia brunneocephala plays a crucial role in forest ecosystems by decomposing wood, thus recycling nutrients back into the soil. This process aids in the decomposition cycle, supporting forest health and regeneration.

Edibility

The edibility of Collybia brunneocephala is not well-documented, and it is generally regarded as inedible due to its small size and insubstantial flesh. As with all wild mushrooms, it should not be consumed unless identified by an expert.

Conservation

There are no known significant threats to Collybia brunneocephala, and it is not listed on any conservation lists. Its presence in a variety of forested environments suggests it is relatively widespread and adaptable.
