Taxonomic Literature: Taxonomic notes: +ascocarp outer wall cells obcscure, irregularly polygonal to rounded, ca. 8-20 µm diam.;Morphologically agreeing with var. mayorii, but asci and appendages different, see below. Braun U., Beih. Nova Hedwigia 89: 1-700 [179-181] (1987); Braun, U. The powdery mildews (Erysiphales) of Europe. - 1-337. Jena, Stuttgart, New York (1995).
