Cortinarius ionodactylus

Unknown

Overview

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

Cortinarius ionodactylus faces significant pressure from habitat degradation in its specialized old-growth forest ecosystems. The species' dependence on specific mycorrhizal relationships with mature trees makes it particularly vulnerable to logging and forest fragmentation. Climate change poses an additional threat by altering the delicate soil chemistry and moisture conditions required for fruiting body development.

Threat summary

Habitat

This fungus inhabits mature coniferous and mixed forests, forming mycorrhizal associations with spruce and fir trees in nutrient-poor, acidic soils. It typically fruits in undisturbed forest floors with thick organic layers and stable moisture conditions.
