　Description： Mycelia epiphyllous, white. Cleistothecia subgregarious to gregarious, globose to subglo-bose, attached at the base to short, straight hyphae on which they are borne, 26-40 × 22-32 μm. Cleistothecial wall of 1 layer of thin, hyaline flattened cells. Appendages none, but wall with short protuberance measuring 2-4 × 2-4 μm on the surface of the cleistothecia. Asci 2 in each cleistothcium, subspherical to spherical, 8-spored, sessile, 24-30 × 16-28 μm. Asco-spores hyaline, ovoid to subglobose, 6-10 × 4-8 μm. Conidia not found.

　Note： This fungus appears to be growing with Erysiphe gracilis mycelia but whether it is a hyperparasite is not absolutely clear. This species is easily distinguished from the other four recognized species namely Brasiliomyces entadae Marasas & Rabie (Marasas, 1966), B. malachrae (Seaver) Boesewinkel (1980), B. setosus Hodges (1985) and B. trina R.-Y. Zheng (1984) by its size and surface structure of cleistothecia, and number of ascospores in each ascus.
