Overview

The Cinnabar Webcap is a distinctive mushroom species characterized by its striking bright red to cinnabar-colored cap and stem, belonging to the large Cortinarius genus known for their cobweb-like partial veils. This mycorrhizal fungus forms essential symbiotic relationships with tree roots, facilitating nutrient exchange and playing a crucial role in forest ecosystem health and soil chemistry.

The Cinnabar Webcap faces significant threats from habitat loss due to deforestation and forest fragmentation, which destroys the specific mycorrhizal relationships this fungus requires with its host trees. Climate change poses additional risks by altering temperature and moisture regimes that are critical for fruiting body development and spore dispersal. Pollution and soil contamination from agricultural runoff and industrial activities further degrade the forest ecosystems where this species occurs.

Threat summary

Habitat
