Index Fungorum number: IF557164


On leaves of Gardenia jasminoides (Rubiaceae). Sexual morph: undetermined. Asexual morph: Conidiomata 600 × 50 μm, dark brown to black, pycnidial, solitary to gregarious, superficial, ovoid to flask-shaped or elongated, unilocular, glabrous, produced on and merging into a basal sterile stalk, expanding slightly in the locular region, finally with a long tapered rostrate apex, sometimes branched. Ostiole apical, centrally located, surrounded by hyaline hyphae. Stalk wall composed of thick-walled, dark brown, parallel columns, longitudinally elongated cells of textura porrecta. Pycnidial wall composed of cuboid brown pseudoparenchyma at the locular region, becoming pale brown, thin-walled, parallel columns, longitudinally elongated pseudoparenchyma at the rostrate apex region. Conidiophores up to 4 μm wide, arising from inner layer of the base and sides of the pycnidial wall, hyaline, cylindrical to subcylindrical, unbranched, septate, smooth-walled, consisting of several cuboid conidiogenous cells. Conidiogenous cells hyaline, enteroblastic, phialidic, cylindrical to dolliform, integrated, determinate, smooth-walled, with apical or lateral apertures immediately below septa, occasionally polyphialidic Conidia 4.5–8 × 2–2.5 μm, hyaline, ellipsoid to cylindrical, unicellular, smooth-walled, guttulate (Sutton 1980).
