Brown Cobblestone Lichen

The Brown Cobblestone Lichen (Acarospora fuscata) is a species in the genus Acarospora. It is currently classified as Least Concern on the IUCN Red List. Native to Europe and North America, inhabiting ecosystems characteristic of the region.

Clitocybe barbularum is a small agaric fungus in the family Tricholomataceae occurring in Northern European temperate and boreal habitats, primarily documented from Scandinavian countries. It grows in grassy areas, woodland clearings, forest margins, and occasionally on disturbed ground, fruiting in late summer through autumn. The fruiting bodies are relatively small and inconspicuous with the characteristic Clitocybe form: a depressed to shallowly funnel-shaped cap, often whitish to pale greyish or buff, with crowded, decurrent gills and a slender stipe. The specific epithet barbularum suggests an association with particular microhabitats or substrates. As a saprotrophic fungus, C. barbularum plays a role in decomposing plant litter and returning nutrients to the soil ecosystem. The broader Clitocybe genus contains both edible and mildly toxic species, and smaller pale species are approached cautiously by foragers. This species reflects the high diversity of macrofungi in Scandinavian landscapes, where boreal and mixed forest systems support exceptional fungal biodiversity.
