Recently, comprehensive molecular
phylogenetic analyses of ribosomal DNA sequences have led to important advances
in understanding the evolution of powdery mildew fungi (Erysiphales). These
results have triggered major changes in the identification, taxonomy, and,
thus, nomenclature of this group of plant pathogens. This paper reviews the
recent nomenclatural changes of the Erysiphales and provides an up-to-date list
of all the powdery mildew fungi reported from Hungary using the new names of
the fungal taxa.
