Summary. A gumming disease of pollard beeches is described which is associated with the presence of Bulgaria polymorpha , Wett. on the trees. A mycelium isolated from the diseased bark has been cultivated and has produced the fructifications of Bulgaria. A pollard has been infected with the disease by grafting in a piece of diseased bark, and also by introducing the mycelium of Bulgaria. Repeated infections of young, vigorous trees with the mycelium failed to produce the disease. It is concluded that Bulgaria is a dangerous facultative parasite on old beeches, but that young healthy trees are able to resist infection. We take this opportunity to record our thanks to M. C. Duchesne, Esq., the Ranger of Burnham Beeches, for the facilities he has readily afforded us and for the information he has placed at our disposal.
