Ochrocladosporium Crous & U. Braun, in Crous et al., Mycol. 58: 46 (2007).

Index Fungorum number: IF 504437; Facesoffungi number: FoF 08175, 3 morphological species (Species Fungorum 2022), 3 species with molecular data.  

         Saprobic on wood pulp. Sexual morph: Unknown. Asexual morph: Mycelium composed of branched, septate, filamentous, hyaline to pale brown, smooth hyphae. Conidiophores semi- macronematous, arising laterally on prostrate hyphae, erect, often reduced to peg-like conidiogenous cells, pale brown, smooth, subcylindrical. Conidia occurring in branched chains, fusiform, ellipsoid-ovoid to subcylindrical, 0(–1)- septate. Ramoconidia present, pale brown, thin-walled, smooth to finely verruculose, attenuated at ends, with obconically truncate to almost pointed, neither thickened nor darkened-refractive hila (adapted from Crous et al. 2007).


Type species: Ochrocladosporium elatum (Harz) Crous & U. Braun


Notes: Ochrocladosporium is characterised by dimorphic conidiophores, conidia mostly aseptate, and hila inconspicuous, neither thickened nor darkened. Ochrocladosporium can be differentiated from Cladosporium s. str. based on DNA sequence data. Phylogenetically, Ochrocladosporium is a distinct and stable lineage within Coniothyriaceae. Molecular markers available for Ochrocladosporium are ITS, LSU and RPB2.
