Overview

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

The Tacked Knight faces severe population declines due to widespread habitat destruction from deforestation and agricultural conversion of its specialized forest ecosystems. Climate change is altering the delicate soil chemistry and mycorrhizal relationships essential for this fungus, while pollution from agricultural runoff and industrial activities degrades the pristine conditions it requires for reproduction and survival.

Threat summary

Habitat

Mature coniferous and mixed deciduous-coniferous forests with well-developed soil layers and established mycorrhizal networks, typically in temperate regions with specific soil pH and moisture conditions. Forms symbiotic relationships with tree roots in undisturbed forest ecosystems, particularly favoring areas with rich organic matter and stable microclimate conditions.
