Paramycoleptodiscus
Paramycoleptodiscus Crous & M.J. Wingf., in Crous et al., Persoonia 36: 371 (2016)
Index Fungorum number: IF 817042; Facesoffungi number: FoF 08093, 1 morphological species (Species Fungorum 2021), 1 species with molecular data.
Saprobic on leaves. Sexual morph: Unknown. Asexual morph: Mycelium consisting of hyaline, branched, septate hyphae that become brown, constricted at septa, forming a cluster of globose, brown, chlamydospore-like cells that form a stroma; stroma brown, solitary, globose, but with age joining along the length of hyphae to become strands of radiating stromata; stroma forming a sporodochium of densely aggregated, dark brown, finely roughened conidiogenous cells, subglobose to slightly ampulliform, containing a single, central phialidic locus, slightly papillate, with cylindrical collarette. Conidia solitary, aseptate, hyaline, smooth, granular, falcate, slightly curved, widest in middle, apex sub obtusely rounded, base with well-defined fusarium-like foot cell (Adapted from Crous et al. 2016).
Type species: Paramycoleptodiscus albiziae Crous & M.J. Wingf.
Notes: Paramycoleptodiscus differs from Mycoleptodiscus (Sutton 1973) in having aseptate conidia with a basal appendage in the form of a foot cell while Mycoleptodiscus has septate conidia with apical appendages. Phylogenetically, Paramycoleptodiscus is a distinct and well-supported genus in Muyocopronaceae. Molecular markers available for Paramycoleptodiscus are ITS, LSU, RPB2 and TEF-1.
