Species Profile
Phellinus lundellii is a species of fungus belonging to the family Hymenochaetaceae. It is found in Eurasia and North America.
The Birch Bristle Bracket (Phellinus lundellii) is critically endangered primarily due to the severe decline and fragmentation of its host habitat - old-growth birch forests. This specialized fungus depends entirely on mature birch trees for survival, making it extremely vulnerable to forest management practices that remove or fragment ancient woodland ecosystems. Climate change further threatens the species by altering forest composition and reducing suitable habitat conditions.
