Overview

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

Rostskinn faces significant pressure from habitat degradation in its specialized forest environments, where logging and land conversion reduce the availability of suitable substrates. Climate change poses an additional threat by altering moisture regimes and temperature patterns that this species depends on for growth and reproduction. The species' limited dispersal ability and specific ecological requirements make it particularly vulnerable to fragmentation of its forest habitat.

Threat summary

Habitat

Rostskinn occurs in mature coniferous and mixed forests, typically growing on dead wood substrates including fallen logs, stumps, and decaying branches. The species requires specific moisture and microclimate conditions found in undisturbed forest environments.
