Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Europe (8 countries), North America (United States), and South America (Ecuador).

Cinnabar Powdercap

Habitat

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

Range

Distributed across Denmark, Norway, Sweden, and United States. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

Cinnabar Powdercap

Cinnabar powdercap (Cystodermella cinnabarina) is a small agaric fungus in the family Agaricaceae, distributed across the Northern Hemisphere in Europe, North America, and parts of Asia. It grows in woodland and forest floor habitats, particularly in needle or mixed leaf litter under conifers and mixed deciduous trees. The fruiting bodies are small to medium mushrooms with a granular, powdery cap surface in shades of orange-red to cinnabar or brick red, which gives the species its name. The gills are white and the stipe has a granular surface below the annulus (ring), typical of the genus. Cystodermella cinnabarina is classified as Vulnerable, reflecting declines linked to eutrophication, changes in forest floor conditions, and the loss of traditional forest management practices that maintained suitable microhabitats. The species is associated with relatively undisturbed, low-nutrient woodland soil conditions and is sensitive to nitrogen enrichment, which promotes competitive vegetation that degrades its habitat. Molecular phylogenetics has clarified its placement within Agaricaceae, separating it from the related genus Cystoderma. The cinnabar powdercap is an indicator of woodland fungi diversity and habitat quality. Conservation of low-intensity managed forest with diverse floor conditions benefits this and related saprotrophic macrofungi.
