\right) \), irregularly arranged to uniseriate near the base, hyaline, learn more aseptate, deeply constricted at the centre, oblong to ovate, with broadly to narrowly rounded ends, the upper part often broader than the lower part, smooth-walled, guttulate. Asexual state not established. Material examined: INDIA, Madras, Presidency, Ootacamund, buy SP600125 Nilgris, on living leaves of Michaelia niliginica, 23 December 1912, W.

Ann. Mycol. 14: 185 (1916) Polysporidium Syd. & P. Syd., Ann. Mycol. 6: 528 (1908) Endophytic or pathogenic on leaves of a wide range of hosts. Ascomata gregarious, circular, brown to black, coriaceous, with a central ostiole. Asci (6-)8–spored, bitunicate, fissitunicate, clavate, with a gelatinous pedicel and ocular chamber. Ascospores irregularly biseriate, hyaline, aseptate, ellipsoid to broadly fusoid, but much wider in the middle, smooth walled, usually with mucilaginous pads at one or both ends or surrounded by a mucilaginous sheath. Pycnidia circular, brown to black, coriaceous, with a central ostiole. Peridium comprising brown cells of textura angularis. Conidiogenous cells lining cAMP wall of pycnidium, phialidic, cylindrical, hyaline. Conidia hyaline, ellipsoidal, aseptate, smooth-walled, surrounded by a mucilaginous sheath bearing a single apical appendage. Notes: Phyllosticta has been reviewed by Wikee et al. (2011a) and there have also been several other modern treatments of the genus (Wulandari et al. 2009; Glienke et al. 2011; Wong et al. 2012). The generic type (Phyllosticta convallariae Pers.) lacks any recent collections or sequence data and this is certainly required. The sexual state Guignardia is clearly linked to Phyllosticta and Wikee et al.
