Broom Hare

The Broom Hare (Lepus castroviejoi) is a species in the genus Lepus. It is currently classified as Vulnerable on the IUCN Red List. Typically found in diverse terrestrial and aquatic ecosystems. This species belongs to the genus Lepus and is documented in taxonomic and ecological literature.

Choiromyces venosus, commonly known as the White Truffle of Finland or the Pig Truffle, is a subterranean (hypogeous) ascomycete fungus in the family Tuberaceae, found in temperate forests of northern and central Europe, extending into Scandinavia. Like the more prized Italian white truffle (Tuber magnatum), it is an ectomycorrhizal fungus, forming symbiotic associations with the roots of forest trees including birch, oak, pine, and spruce. The fruiting bodies develop entirely underground or just at the soil surface, reaching up to 15 centimetres in diameter, with a whitish to cream-coloured, irregularly lobed surface and a marbled interior reminiscent of true truffles. While not as commercially valuable as Tuber species, C. venosus is harvested in parts of Scandinavia and northern Europe and is used in cooking — although it requires preparation as the raw fungus contains volatile compounds that are toxic if consumed in quantity. The IUCN classifies this species as Vulnerable in parts of its range, reflecting declines in habitat quality associated with changes in forest management, nitrogen deposition, and soil disturbance. Monitoring hypogeous fungal populations is inherently difficult, as fruiting bodies are invisible until they emerge and the mycelial network underground cannot be easily surveyed.
