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.

Clitocybe marginella is a small agaric fungus in the family Tricholomataceae found in temperate European woodland and semi-open habitats. Like many members of the diverse Clitocybe genus, it produces modest fruiting bodies with a depressed to funnel-shaped cap and decurrent gills running down the stipe, typically whitish to pale buff in coloration. The species fruits in autumn, colonizing leaf litter, humus-rich soils, and woodland margins where it functions as a saprotrophic decomposer. The epithet marginella may reference subtle marginal features of the cap or gills that help distinguish it from closely related species. Identification within this genus typically requires microscopic examination of spore size and shape, along with assessment of odor, taste, and substrate preferences. European Clitocybe diversity is significant, with dozens of species recorded across forest, grassland, and heathland habitats. C. marginella contributes to the intricate web of decomposer fungi that recycle nutrients in temperate forest ecosystems throughout Northwestern and Central Europe.
