Epiphytic on the dead leaf surfaces appearing as small dark brown to black dots. Superficial hyphae straight to sub straight, dark brown, irregular, easily detached from the host, appressoria not observed. Sexual morph: Undetermined. Asexual morph: Pycnothyria superficial, ostiolate, scattered, rounded to oval, flattened, brown to black, opening by stellate fissures. Upper wall comprising cells of textura prismatica, arranged in parallel rows radiating outwardly from the central ostiole, margin cells branching and forming superficial hyphae. Conidiogenous cells evanescent. Conidia 1-celled, hyaline, cylindrical with obtuse ends, smooth-walled (Tennakoon et al. 2021).

Notes: According to the phylogeny of Tennakoon et al. (2021) indicates that the asexual genus Cylindrohyalospora (C. fici), clusters as a monophyletic clade sister to Melaspileella proximella. Melaspileella is only known from sexual morph and morphological comparison is impossible. Cylindrohyalospora species are characterized by superficial, scattered, rounded to oval, flattened, brown to black pycnothyria, upper wall comprising light brown to dark brown cells of textura epidermoidea and cylindrical, unicellular, hyaline conidia with obtuse ends (Tennakoon et al. 2021).
