Gemarmerde gordijnzwam
Cortinarius chevassutii
Gemarmerde gordijnzwam (Cortinarius chevassutii) is a rare mushroom species characterized by its distinctive marbled or mottled cap coloration and the characteristic cortina (web-like veil) typical of Cortinarius fungi. This mycorrhizal species forms essential symbiotic relationships with tree roots, facilitating nutrient exchange and supporting forest ecosystem health.

Species Profile
Gemarmerde gordijnzwam (Cortinarius chevassutii) is a rare mushroom species characterized by its distinctive marbled or mottled cap coloration and the characteristic cortina (web-like veil) typical of Cortinarius fungi. This mycorrhizal species forms essential symbiotic relationships with tree roots, facilitating nutrient exchange and supporting forest ecosystem health.
Cortinarius chevassutii faces severe threats primarily from habitat loss and degradation of its specialized forest ecosystems. As a mycorrhizal fungus dependent on specific host trees, it is particularly vulnerable to deforestation, forest fragmentation, and changes in forest management practices that alter the delicate soil chemistry and microhabitat conditions required for its survival.
Key Facts
Habitat & Distribution
This species inhabits mature deciduous and mixed forests, particularly those dominated by oak, beech, and other broadleaf trees where it forms mycorrhizal associations. It typically occurs in undisturbed forest soils with rich organic matter and stable moisture conditions.
