Overview

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

The Northern Tooth faces significant decline due to the loss of old-growth forests containing the large, mature hardwood trees it requires for fruiting. Logging operations and forest fragmentation have reduced suitable habitat, while climate change may be altering the specific moisture and temperature conditions this fungus needs. The species' dependence on aging and dying trees makes it particularly vulnerable to forest management practices that remove dead wood.

Threat summary

Habitat

Northern Tooth grows as a saprophyte on dead and dying hardwood trees, particularly favoring mature deciduous forests with substantial amounts of decaying wood. It typically fruits on the trunks and large branches of oak, maple, and other broadleaf species in temperate forest ecosystems.
