Silverleaf fungus

Chondrostereum purpureum


Silver leaf is a fungal disease of trees caused by the fungus plant pathogen Chondrostereum purpureum. The common name is taken from the progressive silvering of leaves on affected branches. This fungus forms leathery, lilac to deep purple patches with a white edge. After starting as just a crust on the wood, the fruiting structure develops undulating intergrowing brackets up to about 3 cm broad.


It is often found on old stumps and dead wood, but can also be a serious parasite of living trees.


Spotted on a fallen unidentified tree in Spielderbos, Veluwe, Holland. (sources:see reference)
