As а result of lengthy investigationпs in the south of the Soviet Far East, the author detected 84 species аnd 129 forms of Erysiphales оn 442 host plants of 53 angiosperm families. This paper gives evidence on the morphology, biology" ecology, nomenclature, taxonomics and geographical distribution of the said fungi group. The percentage of taxons in Erysiphales with Holarctic, Eurasian, American-Asian, Far Eastern endemic; Asian, and hemicosmopolitan areas was found to bе 48, 19, 11.2, 11.7, 2.7 аnd 7.4%, respectively. Six heretofore unknown species and sixteen forms were detected mаinlу on specific Far Eastern plants. For the first time, hitherto unpublished diagnoses for 3 species and 8 forms are given. Calcifile fungi from lime mountains in southern Primorye are also described.
