Silver leaf

Silver leaf

Silver leaf or "Chondrostereum purpureum" is a fungal disease of trees. It attacks most species of the rose family Rosaceae, particularly the genus Prunus. The disease is progressive and often fatal. The common name is taken from the progressive silvering of leaves on affected branches. It is spread by airborne spores landing on freshly exposed sapwood. For this reason cherries and plums are pruned in summer, when spores are least likely to be present.

In the past the name "Stereum purpureum" was commonly used, but according to modern taxonomy this fungus is only very distantly related to "Stereum", actually belonging to order Polyporales whereas "Stereum" is in order "Russulales".
