Nomenclature: Current taxonomic status: accepted or basionymous. Taxonomic rank: species. Erysiphaceae Tul. & C. Tul.; Erysiphales.

Type Information: Type: Oidiopsis taurica var. macrospora Uppal, Patel & Kamat.

Taxonomic Literature: Taxonomic notes: +conidophores septate, simple, often branched, emerging singly or in fascicles through the stomata, up to 280 µm long, also arising from the external mycelium, with short appressorium-like structures;. Braun U., Beih. Nova Hedwigia 89: 1-700 [619] (1987).

Biogeography: Continent: Asia-Tropical. Country or state(s): India.

Ecology: Biotroph (mycelium internal as well as external, forming dull red spots on the dorsal surface and mealy white growth on the lower surface of the leaves, external mycelium hypophyllous, internal mycelium intercellular with globose haustoria); phytopathogenic (mycelium internal as well as external, forming dull red spots on the dorsal surface and mealy white growth on the lower surface of the leaves, external mycelium hypophyllous, internal mycelium intercellular with globose haustoria).

Conidiomata: Present; hyphomycetous.

Conidiophores: Not branched. Conidium Formation: Conidiogenous cells single. Conidia: Sub-cylindrical (or irregular in shape, either with a swelling or with a constriction in the middle); macroconidial (germination by production of germ tubes which immediately penetrate through the stomata), not branched, somewhat acuminate at one end (sometimes), 74-111 µm long, 10-34 µm wide; aseptate.
