Clitocybe augeana is a saprotrophic agaric fungus in the family Tricholomataceae native to Northern European forests and grasslands, with principal records from Scandinavia. It produces modest fruiting bodies with the genus-typical depressed to funnel-shaped cap, whitish to pale greyish coloration, and decurrent gills running down the stipe. Like many Clitocybe species, it emerges during autumn in habitats ranging from deciduous and mixed woodland floors to grassy clearings and forest margins, where it decomposes accumulated leaf litter and organic matter. The taxonomy of smaller, pale Clitocybe species has undergone considerable revision through molecular phylogenetic studies, with several species previously grouped together now recognized as distinct entities based on spore morphology, habitat preferences, and DNA sequence data. C. augeana contributes to the rich diversity of macrofungi documented in Scandinavian boreal and nemoral forests, ecosystems recognized for their exceptional fungal species richness and ecological importance in nutrient cycling processes.
