Abstract

In forests of North America the beech bark disease (BBD) complex affects American beech, Fagus grandifolia Ehrh. BBD begins when bark tissues, attacked by the exotic beech scale insect, Cryptococcus fagisuga Lind. are rendered susceptible to killing attacks by fungi of the genus Nectria. The principal fungus, N. coccinea var. faginata Lohm. and Watson, was probably introduced also, but the native pathogen, N. galligena Bres., also attacks and kills bark predisposed by C. fagisuga.
