Range

Widely distributed across Europe (4 countries), North America (United States), and South America (Brazil).

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 scyphoides is an agaric fungus in the family Entolomataceae found in temperate European woodlands and grassland habitats. The species epithet scyphoides refers to a cup- or goblet-like form ('scyphus' meaning cup in Latin), likely describing the mature cap shape which becomes deeply depressed to funnel-shaped at maturity. Like other Clitopilus species, it produces white to pale cap surfaces, crowded decurrent gills that develop a pinkish tinge from the angular spores as they mature, and typically exhibits a mealy or farinaceous odor. It fruits in autumn in woodland clearings, beech and oak woodland floors, and occasionally in grassy habitats. The Clitopilus genus contains around a dozen recognized European species, some of which resemble the edible sweetbread mushroom C. prunulus. Molecular and morphological studies continue to clarify species boundaries and relationships within the genus. C. scyphoides contributes to the decomposer fungal community in its habitats, processing leaf litter and soil organic matter within temperate European forest and grassland 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.
