Hyphae undulateto crooked, branching alternate to unilateral at acuteangles, loosely to closely reticulate, cells 17–23x4–6µm. Appressoria alternate, unilateral, two celled,straight to variously curved, smooth to variously bulged,entire to lobate, 5–10 µm long; head cells clavate,ovate, cylindrical, hamate, straight to curved, 3–7 timessublobate to lobate, 7–13x11–13 µm. Thyriotheciascattered, orbicular, up to 150µm in diameter, stellatelydehisced at the center, margin fringed, fringed hyphaeflexuous, exappressoriate; asci globose, octosporous,22–33 µm in diameter; ascospores oblong, cylindrical,brown, uniseptate, strongly constricted at the septum,20–25x10–13 µm, wall echinulate.Material examined: 03.iii.2009 on leaves <strong>of</strong> Jasminumsp.
