Helotiales

Drepanopezizaceae

Facesoffungi number: FoF 05864
Taxa are plant pathogenic (Dimova et al. 2014, Blechert & Debener 2005, Samuels et al. 1981, Spiers & Hopcroft 1998, Pearson et al. 1988). Ascomata are apothecial. Apothecia are cupulate, sessile and mostly immersed. The excipulum is a thin layer, composed of cells of textura angularis. Paraphyses are apically slightly swollen and straight. Asci are 4–8- spored, apex obtuse to conical and non-amyloid. Ascospores are ellipsoid to fusoid and aseptate or 1–2-septate (Samuels et al. 1981, Spiers & Hopcroft 1998, Korf et al. 1986). Asexual morphs are hyphomycetous, acervulus. Conidiogenesis is holoblastic. Conidia are sometimes two types, macroconidia are ellipsoid to fusoid and slight curved and microconidia are sometimes present and ellipsoid to bacilliform (Konig et al. 2009, Yoshikawa & Yokoyama 1992).
Notes – This is a highly plant pathogenic family within Leotiomycetes, which cause leaf spot, early defoliation, chlorosis and leaf and twig blight of various dicotyledons including poplars, leek, cherry, rose and grape (Dimova et al. 2014, Blechert & Debener 2005, Samuels et al. 1981, Spiers & Hopcroft 1998, Pearson et al. 1988, Lee et al. 2011, Rossman et al. 2018).
