The anamorph found on this host agrees well with the North American Podosphaera pruinosa. Although the teleomorph has not yet been found in Germany and a molecular study has not yet been possible due to the lack of fresh North American material for a comparison, there is little doubt that the European outbreak of the Rhus powdery mildew disease may be referred to as Podosphaera pruinosa. Morphology, taxonomy and distribution of Podosphaera species on Rhus and other hosts of the Anacardiaceae are discussed in detail.},

An Oidium morphologically agreeing with the anamorph of Podosphaera aphanis has recently been collected on Exacum macranthum cultivated in a greenhouse, and conidiophores and conidia of a species of Podosphaera sect.

  abstract  = {The new species Erysiphe asclepiadis is described, illustrated and discussed. A new Chinese collection of Erysiphe robiniicola has recently been found that can be used to elucidate and discuss the confused taxonomy and nomenclature of this species and other taxa of Erysiphe s. lat. on Robinia spp. Based on a re-examination of type material in connection with the data given in the protologue, it can be shown that Capnodium lygodesmiae must be reduced to synonymy with Ampelomyces quisqualis. The confusion surrounding the name C. lygodesmiae, caused by the occurrence of the hyperparasite A. quisqualis on a powdery mildew fungus with abundant chasmothecia, is discussed in detail. The new combination, Golovinomyces caulicola (; Spolverinia caulicola), is proposed for the powdery mildew that serves as host of C. lygodesmiae.},
