Cortinarius cordatae
Local name: ladegårdsslørsopp
Cortinarius cordatae (ladegårdsslørsopp) is a rare mushroom species belonging to the webcap family, characterized by its distinctive rusty-brown spores and cobweb-like partial veil that gives the genus its common name. This fungus forms essential mycorrhizal partnerships with specific tree species, playing a crucial role in forest nutrient cycling and supporting the health of its host trees through symbiotic root associations.

Species Profile
Cortinarius cordatae (ladegårdsslørsopp) is a rare mushroom species belonging to the webcap family, characterized by its distinctive rusty-brown spores and cobweb-like partial veil that gives the genus its common name. This fungus forms essential mycorrhizal partnerships with specific tree species, playing a crucial role in forest nutrient cycling and supporting the health of its host trees through symbiotic root associations.
Cortinarius cordatae faces severe threats primarily from habitat loss and degradation of its specialized old-growth forest ecosystems. The species has an extremely limited distribution and appears to be dependent on specific ecological conditions that are increasingly rare due to forestry practices and environmental changes.
Key Facts
Habitat & Distribution
Cortinarius cordatae occurs in mature deciduous and mixed forests, particularly favoring areas with rich, well-drained soils beneath beech, oak, and birch trees. The species requires stable forest floor conditions with consistent moisture levels and minimal soil disturbance to maintain its mycorrhizal networks.
Threats
