Parauncinula polyspora is a species of powdery mildew in the family Erysiphaceae. It is found on plants in the genus Quercus in Asia. It is only known from Japan.[1]
Description
[edit]The fungus forms effuse, evanescent mycelium on the leaves of its host. Parauncinula polyspora, like most Erysiphaceae, is highly host-specific and infects only Quercus. Parauncinula septata is also found on the same hosts but generally has fewer spores per ascus.[1] Parauncinula uncinata is found only on Quercus variabilis and has appendages with uncinate tips and septa not reaching the upper part of the appendages.
Taxonomy
[edit]The fungus was formally described in 2017 by Meeboon and Takamatsu based on slight morphological differences but very different ITS sequences to Parauncinula septata.
