Biotrophic members of the Phyllachoraceae are described and illustrated, and their nomenclature assessed. Isothea is considered to be a monotypic genus with close affinities to Phyllachora. Four species of Phyllachora are accepted; some have distinctive features which may provide evidence for subdivision of that genus. Two species currently referred to Plectosphaera are studied; neither is a typical biotroph. Polystigma is formally monographed. Five species are accepted, all on species of Prunus, including the previously undescribed P. amygdalinum, an economically important pathogen of almond (Prunus dulcis). An eastern Russian species originally described in Polystigmella is treated as a subspecies of the widespread plum pathogen Polystigma rubrum. A number of species names is excluded from the Phyllachoraceae.
