The results of investigation of phytopathogenic micromycetes of the family Erysiphaceae occurring in phytocenoses of Cuba and Isla de la Juventud are summarized in this paper. They are dealing mainly with their host range, distribution and their morphological characteristics. Mentioned group of the fungi was detected on 78 plant species belonging to 62 genera and 16 families. They parasited mainly on species of the family Fabaceae (on 22 species from 13 genera) and Asteraceae (on 15 species from 14 genera), further on Euphorbiaceae (9 species from 6 genera), Malvaceae (6 species from 5 genera), Cucurbitaceae (4 species from 3 genera), Boraginaceae (3 species from 2 genera), as well as on species of the families Anacardiaceae, Balsaminaceae, Bixaceae, Brasicaceae, Caricaceae, Lythraceae. Rosaceae and Zygophyllaceae (only one species of the host plants). The fungi of the family Erysiphaceae occurred only in anamorphous stage. There is a growing tendency in the intensity of occurrence of mentioned group of micromycetes in Cuba. They are strongly parazitized by the mycoparasite Ampelomyces quisqualis Ces., too.
