Overview

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

Hyphodermella corrugata faces severe decline due to the loss of old-growth deciduous forests, particularly beech and oak woodlands that provide the specific bark chemistry and microclimate conditions this corticioid fungus requires. Intensive forest management practices that remove dead and dying trees eliminate the substrate this species depends on for reproduction and survival. Air pollution and acid deposition further threaten remaining populations by altering bark pH levels and disrupting the delicate chemical balance needed for spore germination.

Threat summary

Habitat

This corticioid fungus grows exclusively on the bark of mature deciduous trees, particularly beech and oak species in old-growth and semi-natural forests. It requires specific microclimate conditions found in undisturbed woodland environments with high humidity and stable temperature regimes.
