Baeomyces

About

Baeomyces is a genus of lichen-forming fungi in the family Baeomycetaceae. Members of Baeomyces are commonly called beret lichens. These lichens are radily recognised by their distinctive "matchstick" appearance, with small brown fruiting bodies held up on short stalks above a crusty base. They typically grow in disturbed habitats such as roadsides, bare soil, and mining sites, where they act as pioneer colonisers of acidic ground.
