Overview

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

The Zoned Tooth faces severe decline due to nitrogen pollution from agricultural runoff and atmospheric deposition, which fundamentally alters soil chemistry in its preferred habitats. Forest fragmentation and intensive logging practices have eliminated many of the old-growth coniferous stands this mycorrhizal fungus requires for survival. Climate change compounds these pressures by disrupting the delicate soil conditions and host tree relationships essential for fruiting body development.

Threat summary

Habitat

The Zoned Tooth inhabits mature coniferous forests, particularly those dominated by spruce and pine, where it forms mycorrhizal associations with tree roots in nutrient-poor, acidic soils. This species requires undisturbed forest floors with stable soil chemistry and is typically found in old-growth stands with minimal human disturbance.
