Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Cortinarius rufo-olivaceus faces severe 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 is altering temperature and moisture regimes in its native forest ecosystems, while pollution and soil contamination further degrade the delicate conditions necessary for its survival.

Threat summary

Habitat

This species occurs in mature deciduous and mixed forests, particularly in association with oak and beech trees where it forms essential mycorrhizal relationships. It typically inhabits well-drained forest soils with rich organic matter in temperate woodland ecosystems.
