Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Polar bear

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Clitocybe foetens is a notably malodorous agaric fungus in the family Tricholomataceae, with the species epithet foetens Latin for 'stinking' or 'fetid,' reflecting its distinctive unpleasant odor that sets it apart from many related species. It occurs across temperate European forests, particularly in deciduous and mixed woodlands, where it fruits among leaf litter and organic debris during autumn. The cap is convex to shallowly depressed, pale brownish to greyish-buff, with decurrent gills and a slender stipe bearing the characteristic Clitocybe morphology. The strong, disagreeable smell is likely produced by volatile compounds and serves as a chemical signal, though whether it deters or attracts invertebrates and other fauna varies by compound chemistry. Like other genus members, C. foetens is a saprotrophic decomposer contributing to litter breakdown in temperate forest ecosystems. The fetid odor also serves as a useful distinguishing character for mycologists working in this taxonomically complex genus of small, pale-capped agarics found throughout European woodland habitats.

Polar bear

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
