The Bog Bonnet (Mycena concolor) is a species in the genus Mycena. It is currently classified as Vulnerable on the IUCN Red List. Distributed across Denmark, Norway, and Sweden.

Clustered Bonnet

Mycena inclinata, the clustered bonnet, is a small saprotrophic fungus in the family Mycenaceae that typically grows in dense clusters at the base of oak stumps and oak logs, and occasionally on beech or other hardwoods across the northern hemisphere. The fruiting bodies are graceful, with a broadly conical to bell-shaped cap typically pale greyish-brown, darkening toward the center, and a slender, brittle stem. One distinctive feature is the finely serrated or frilly-edged (frosted) lower stipe. The gills are white, later with pinkish tints in old specimens. M. inclinata has a distinctive mealiness or rancid smell compared to some other Mycena species, and it causes white rot in its woody substrate. It is widespread and common in deciduous and mixed woodlands throughout Europe and North America, fruiting from late summer through late autumn. The clustered growth habit on oak wood is characteristic and aids identification. The genus Mycena is large, with hundreds of species globally, many requiring microscopic examination for certain identification. M. inclinata is classified as Least Concern given its abundance and wide distribution.
