Clitocybe amarescens is a small, bitter-tasting agaric fungus in the family Tricholomataceae distributed across Northwestern and Northern Europe, with confirmed records from Belgium, Denmark, Norway, and Sweden. The specific epithet amarescens reflects the notably bitter flavor of the fruiting bodies, a characteristic that distinguishes it from some closely related Clitocybe species. The cap is typically whitish to pale greyish, smooth, with decurrent gills characteristic of the genus, and fruits in woodland margins, grassy clearings, and other semi-open habitats during autumn months. Like other Clitocybe species, it is a saprotrophic fungus contributing to decomposition of leaf litter and organic debris. The bitter taste likely serves as a deterrent against invertebrate predation. The species is assessed as Least Concern across its European range but, like other fungi of unimproved grasslands and forest margins, remains potentially sensitive to habitat changes driven by agricultural intensification, fertilizer application, and loss of structurally diverse woodland edges across Scandinavia and Western Europe.
