Overview

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

The Yellow Knight faces severe decline due to widespread habitat destruction from intensive forestry practices and urban development across its European range. Climate change is altering the delicate mycorrhizal relationships this species depends on with pine trees, while soil acidification from pollution disrupts the specific pH conditions required for fruiting. Overcollection by commercial and recreational foragers has further reduced populations, particularly in accessible forest areas near urban centers.

Threat summary

Habitat

Yellow Knight forms mycorrhizal associations exclusively with pine trees, particularly Scots pine, in sandy, well-drained soils across coniferous and mixed forests. The species requires specific soil pH conditions and is typically found in mature forest stands with established pine root systems.
