Overview

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

The Scarlet Brittlegill faces significant pressure from habitat degradation as old-growth coniferous forests are cleared for timber harvesting and urban development. Climate change poses an additional threat by altering the delicate soil chemistry and mycorrhizal relationships essential for this fungus's survival. The species' specialized ecological requirements and limited dispersal ability make it particularly vulnerable to forest fragmentation.

Threat summary

Habitat

The Scarlet Brittlegill is found exclusively in mature coniferous forests, particularly those dominated by spruce and fir species. It forms mycorrhizal associations with tree roots and requires specific soil conditions and forest floor chemistry typical of undisturbed old-growth ecosystems.
