Cordana Preuss, Linnaea 24: 129 (1851)

Diaporthomycetidae, Magnaporthales, Pyriculariaceae, Cordana

Index Fungorum number: IF7777; Facesoffungi number: FoF 01674; 23 morphological species (Species Fungorum 2020), 11 species with sequence data.


Saprobic or pathogenic on wood of branches, twigs and leaves of various shrubs and trees, bamboo, grasses and in soil of terrestrial habitats, occasionally in freshwater habitats. Sexual morph: Ascomata perithecial, superficial, solitary or gregarious, globose to ovoid, setose or glabrous, with basal stroma, papillate. Ostiole periphysate. Peridium comprising 3–5 layers of cells of textura prismatica. Paraphyses septate, unbranched. Asci 8-spored, unitunicate, cylindrical, with short pedicel, with or without a J-, apical ring. Ascospores uniseriate, pale brown to brown, ellipsoid to fusiform, sometimes with pores at both ends, 1-septate. Asexual morph: Hyphomycetous. Colonies effuse, dark brown to black. Conidiophores mononematous, macronematous, brown, septate, erect, branched or unbranched. Conidiogenous cells terminal or intercalary, polyblastic, denticulate. Conidia pale brown to brown, obovoid to ellipsoidal, smooth, sometimes with germ pores at the ends, 1-septate or aseptate (adapted from Hughes 1955, Müller & Samuels 1982, Hernández-Restrepo et al. 2014).


Type species: Cordana pauciseptata Preuss, Linnaea 24: 129 (1851)


Notes: Cordana is a dematiaceous hyphomycetous genus introduced by Preuss (1851) together with three species, C. polyseptata, C. pauciseptata and C. pedunculata, without designation of a type species (Hernández-Restrepo et al. 2014). Saccardo (1877) and Hughes (1955) attempted to designate C. pauciseptata as the lectotype, however in both occasions the species was subjected to reclassification and the type material was reported as lost (Hernández-Restrepo et al. 2014). Thus, Hernández-Restrepo et al. (2014) designated an epitype for this genus, produced a phylogram based on ITS sequences and provided a dichotomous key to the species. Based on cultural studies, Müller & Samuels (1982) suggested Porosphaerella cordanophora was the sexual morph of Cordana pauciseptata, and this was confirmed phylogenetically by Hernández-Restrepo et al. (2014). ITS sequence data for eight species and LSU for some are available in GenBank (Réblová & Winka 2000, Huhndorf et al. 2004, Réblová & Seifert 2007, Hernández-Restrepo et al. 2014, Zelski et al. 2014, Vu et al. 2019).
