Range

Distributed across Denmark, Norway, and Sweden.

Laysan Duck

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and Mediterranean forests and woodlands within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Belgium, France, Netherlands, Norway, and United Kingdom. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Clitopilus daamsii is an agaric fungus in the family Entolomataceae named in honor of a mycologist contributing to European fungal taxonomy. Like other Clitopilus species, it produces fruiting bodies with white to pale grey caps, crowded, decurrent gills that become pinkish at maturity due to the development of angular, pink-tinged spores, and a mealy or farinaceous odor and taste characteristic of the genus. It inhabits deciduous woodland floors, woodland margins, and occasionally grassy habitats in temperate Europe, where it fruits in autumn among leaf litter. The genus Clitopilus includes both edible species, most notably C. prunulus (the sweetbread mushroom), and potentially confusable species. Accurate identification of Clitopilus species relies on spore morphology, odor, taste, gill attachment, and habitat. C. daamsii represents the diversity of named entolomatoid species emerging from detailed European mycological surveys, reflecting ongoing efforts to document and describe the full diversity of fungal life in temperate ecosystems.

Laysan Duck

Laysan Duck (Anas laysanensis) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.
