Overview

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

The Twotone Woodwax faces severe population declines due to widespread habitat destruction from deforestation and urban development in its specialized forest ecosystems. Climate change is altering the delicate moisture and temperature conditions required for this fungus to fruit and complete its life cycle. Additionally, soil contamination and changes in forest composition are disrupting the mycorrhizal relationships essential for its survival.

Threat summary

Habitat

Inhabits mature coniferous and mixed forests, particularly in moist, well-drained soils with abundant organic matter. Forms mycorrhizal associations with tree roots in temperate forest ecosystems, typically fruiting in late summer and autumn.
