Gordonomyces
Gordonomyces Crous & Marinc., in Crous et al., Persoonia 27: 39 (2011).
Index Fungorum number: IF 560568; Facesoffungi number: FoF 08244, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on leaf. Sexual morph: Unknown. Asexual morph: Conidiomata up to 600 µm diam., globose, separate to aggregated in clusters, black, outer wall smooth; wall of textura angularis, up to 60 µm thick, outer region of 3–8 layers of dark brown cells, inner region of 3–7 layers of thick-walled, hyaline cells. Paraphyses intermingled among conidiogenous cells, cylindrical, branched below, septate; at times becoming fertile. Conidiogenous cells subcylindrical to ampulliform, mostly reduced to single cells, with apical percurrent proliferation. Conidia medium to golden-brown, verruculose, obovoid to semiclavate, medianly 1-euseptate, apex obtuse, base subtruncate, conidia covered in mucoid sheath (adapted from Crous et al. 2011).
Type species: Gordonomyces mucovaginatus Crous & Marinc.
Notes: Gordonomyces is characterised by globose conidiomata, subcylindrical to ampulliform conidiogenous cells, and medium to golden-brown, verruculose conidia. Gordonomyces is phylogenetically related to Fusculina. Gordonomyces morphologically differs from Fusculina in that the latter has amphigenous conidiomata, ellipsoid conidia with rounded ends, or subcylindrical with obtuse apex and truncate base. Gordonomyces is a distinct genus in Fusculinaceae. Molecular markers available for Gordonomyces are ITS and LSU.
