Overview

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

The Marshmallow Polypore faces severe threats from widespread deforestation and habitat fragmentation across its range, particularly affecting the old-growth forests it depends upon for suitable host trees. Climate change is altering forest composition and moisture regimes critical for this fungal species, while increased human development continues to reduce available habitat.
