Overview

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

The Soapy Trich faces severe population declines primarily due to widespread habitat degradation from intensive forestry practices that alter soil chemistry and mycorrhizal networks essential for this ectomycorrhizal species. Urban development and agricultural expansion have fragmented its woodland habitats, while climate change is shifting temperature and moisture regimes beyond the species' tolerance range. Pollution from agricultural runoff and atmospheric nitrogen deposition further compromises the delicate soil conditions required for fruiting body formation.

Threat summary

Habitat

The Soapy Trich inhabits deciduous and mixed woodlands, forming ectomycorrhizal associations primarily with oak, beech, and birch trees in well-drained, slightly acidic soils. It typically fruits in mature forest understories with stable leaf litter layers and established fungal networks.

Why is Soapy Trich classified as Endangered?
Soapy Trich is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. The Soapy Trich faces severe population declines primarily due to widespread habitat degradation from intensive forestry practices that alter soil chemistry and mycorrhizal networks essential for this ectomycorrhizal species. Urban development and agricultural expansion have fragmented its woodland habitats, while climate change is shifting temperature and moisture regimes beyond the species' tolerance range. Pollution from agricultural runoff and atmospheric nitrogen deposition further compromises the delicate soil conditions required for fruiting body formation.
Where does Soapy Trich live?
