Overview
Phellinus tremulae, the aspen bracket, is a species of polypore fungus in the family Hymenochaetaceae that grows on Populus tremula and on trembling aspen in Canada. The species was first described as Fomes igniarius f. tremulae by Appollinaris Semenovich Bondartsev in 1935. It causes the disease Aspen trunk rot.
Aspen Fomes faces significant threats from habitat loss due to deforestation and forest management practices that reduce the availability of its host trees. Climate change poses additional risks by altering forest composition and affecting the health of aspen populations that this fungus depends upon for survival.
Habitat
This parasitic fungus occurs exclusively on aspen trees (Populus tremula and related species) in temperate and boreal forests across northern regions. It typically inhabits mature aspen stands where it forms bracket-like fruiting bodies on living and dead aspen wood.
