Overview

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

Diplomitoporus crustulinus faces severe decline due to the widespread loss of old-growth coniferous forests across its range. The species requires mature spruce and fir trees with specific bark chemistry and moisture conditions that are increasingly rare due to intensive forestry practices. Climate change compounds these pressures by altering forest composition and increasing the frequency of droughts that stress host trees.

Threat summary

Habitat

This polypore fungus grows exclusively on the bark of mature coniferous trees, particularly Norway spruce and silver fir in montane and boreal forests. It requires old-growth forest conditions with high humidity and minimal disturbance, typically found at elevations between 500-1500 meters.
