Cortinarius arcifolius
Local name: Bogenblättriger Klumpfuß
Bogenblättriger Klumpfuß (Cortinarius arcifolius) is a distinctive webcap mushroom characterized by its robust, club-shaped stem and cap with curved, bow-like gill attachments that give it its German name meaning 'bow-leaved clubfoot.' This mycorrhizal fungus forms essential symbiotic relationships with coniferous trees, facilitating nutrient exchange and supporting forest ecosystem health.

Species Profile
Bogenblättriger Klumpfuß (Cortinarius arcifolius) is a distinctive webcap mushroom characterized by its robust, club-shaped stem and cap with curved, bow-like gill attachments that give it its German name meaning 'bow-leaved clubfoot.' This mycorrhizal fungus forms essential symbiotic relationships with coniferous trees, facilitating nutrient exchange and supporting forest ecosystem health.
Bogenblättriger Klumpfuß faces significant threats from habitat degradation due to forest fragmentation, pollution, and climate change impacts on soil chemistry. The species' specialized mycorrhizal relationships with specific tree hosts make it particularly vulnerable to ecosystem disruption and changes in forest composition.
Key Facts
Habitat & Distribution
This fungal species occurs in temperate deciduous and mixed forests, forming mycorrhizal associations with broadleaf trees, particularly in calcareous soils and woodland edges. It typically fruits in late summer to autumn in mature forest ecosystems with stable soil conditions.
Threats
