Tardy Brittlegill

Russula cessans

Unknown

Overview

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

The Tardy Brittlegill faces severe population decline primarily due to the destruction and fragmentation of its specialized old-growth forest habitats across Europe. Intensive forestry practices that remove mature trees and alter soil chemistry have eliminated many historical populations. Climate change compounds these pressures by shifting temperature and moisture regimes that this mycorrhizal species depends on for successful fruiting and spore dispersal.

Threat summary

Habitat

This mycorrhizal fungus forms symbiotic relationships with deciduous trees, particularly beech and oak, in mature European forests with rich, calcareous soils. It requires stable forest ecosystems with minimal disturbance and specific soil pH conditions to complete its complex life cycle.
