Brown Rat

Brown Rat (Rattus norvegicus) is classified as Least Concern (LC) on the IUCN Red List. Widespread and abundant across its range, with stable populations and no immediate conservation concerns.

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.
