Rhytismataceae
Facesoffungi number: FoF 05946
Taxa are saprobic on dead plant material or parasitic (Wang et al. 2006a). Ascomata are apothecial. Apothecia are long-stipitate, clavate, capitate or spathulate or sessile, erumpent, circular, navicular or hysteriform, clypeate and opening by longitudinal split or radial fissures. The ectal excipulum is composed of cells of textura angularis or textura porrecta and medullary excipulum is reduced or composed of cells of textura intricata to prismatica. Paraphyses are rarely absent, filiform, mostly aseptate, branched or unbranched, sometimes apically slightly swollen and strongly curved and hyaline. Asci are 4–8-spored, mostly non-amyloid, cylindric-clavate and arising from croziers. Ascospores are ovoid, ellipsoid, clavate, sub-cylindrical, fusoid or filiform, hyaline, usually aseptate, apex slightly curved, base strongly tapered and sometimes apex partly covered by a gel cap (Wang et al. 2006a, Ge et al. 2014, Geesteranus 1972, Wang et al. 2002, 2006b, Cannon & Minter 1986, Johnston 2001a, b, Minter 1981, Sherwood 1980, Hou & Piepenbring 2006, 2009, Tanney & Seifert 2017). Asexual morphs are pycnidial. Conidiogenesis is holoblastic, with sympodial proliferation. Conidia are ellipsoid to fusoid, rod-shape, hyaline and aseptate (Hou & Piepenbring 2006, Wang et al. 2006a, Ge et al. 2014).
