Ganoderma resinaceum

Unknown

Overview

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

Ganoderma resinaceum faces severe decline due to the loss of old-growth deciduous forests, particularly those containing ancient oak and beech trees essential for its parasitic lifecycle. Urban development and intensive forestry practices have fragmented its habitat across Europe, while climate change alters the moisture and temperature conditions this polypore requires for fruiting body development. The species' dependence on mature tree hosts makes it especially vulnerable to forest management practices that remove dead and dying trees.

Threat summary

Habitat

This polypore fungus inhabits mature deciduous forests, growing as a parasite and saprophyte on old oak, beech, and other broadleaf trees. It requires stable forest environments with consistent moisture levels and typically occurs in undisturbed woodland areas with abundant dead wood.
