Typus: Mauritius, on leaves of Musa sp., 1 Jan. 2005, collected by Y. Jaufeerally-Fakim, CBS-H 19777, holotypus; cultures ex-type CPC 11237 = CBS 120026, CPC 11238-11239. Original description (Arzanlou, M.; Crous, P.W. 2006, Fungal Planet no. 9) Description: Leaf spots amphigenous, but more prominent on the upper leaf surface, pale brown to grey, surrounded by a dark brown margin, irregular, elongated, up to 6 mm wide. Ascomata amphigenous, occurring separately, or on older lesions in association with other leaf spot pathogens. Ascomata brown, up to 130 µm diam; wall consisting of 2-3 layers of brown cells of textura angularis. Asci bitunicate, subcylindrical, stipitate, fasciculate, 8-spored, 38-60 x 7-8 µm. Pseudoparaphyses intermingled among asci, hyaline, branched, septate, 1-2 µm diam. Ascospores fusoid-ellipsoidal with obtuse ends, widest in the cell above the primary septum, 3-septate, brown, verruculose, guttulate, (15-)17-19(-21) x (3.5-)4 µm. Ascospores germinating predominently from polar ends, with germ tubes growing down into the agar; germinating spores distorting, becoming up to 8 µm wide. Conidiomata pycnidial, brown, formed in and on agar surface, up to 300 µm diam. Conidiogenous cells ampulliform to doliiform, hyaline to pale brown, proliferating percurrently, 5-7 x 3-5 µm. Conidia obclavate, apex subacutely rounded, base obconically subtruncate, 1-4-septate, pale brown, smooth, (17-)20-30(-35) x (2-)3-4 µm. Cultural characteristics: Colonies flat, spreading, with sparse to moderate aerial mycelium; margins smooth, regular. Colonies isabelline on 2 % malt extract agar (MEA; Oxoid)1, with sepia outer zone, and sepia in reverse; colonies reaching 30 mm diam after 1 month on MEA at 25 °C; colonies fertile, producing the anamorph in culture. Typus: Mauritius, on leaves of Musa sp., 1 Jan. 2005, collected by Y. Jaufeerally-Fakim, CBS-H 19777, holotypus; cultures ex-type CPC 11237 = CBS 120026, CPC 11238-11239.
