Overview

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

The Winecork Brittlegill faces severe threats from widespread habitat degradation and loss of mature forest ecosystems essential for its mycorrhizal relationships. Climate change and atmospheric pollution are disrupting the delicate soil chemistry and fungal networks this species depends on for survival. Conservation status may vary by region or assessment authority, but declining populations reflect the broader crisis facing forest-dependent fungi.

Threat summary

Habitat

Mature deciduous and mixed forests, particularly those dominated by beech, oak, and birch trees with which it forms essential mycorrhizal partnerships. Typically found in well-established woodland ecosystems with rich, undisturbed soil layers and stable microclimate conditions.
