Gliocladiopsis S.B. Saksena, Mycologia 46: 662 (1954)
Hypocreomycetidae, Hypocreales, Nectriaceae, Gliocladiopsis
Index Fungorum number: IF8341; 14 species with sequence data.
Saprobic or pathogenic. Sexual morph: Ascomata perithecial, superficial, aggregated, stromatic, obovoid to broadly obpyriform, warted, collapsing laterally upon drying, ostiolate; KOH+, turning red-brown. Ostioles containing tubular periphyses with round ends. Peridium 2-layered; outer layer made up of thick-walled cells of textura globulosa, inner layer comprising compressed cells of textura angularis. Asci 8-spored, unitunicate, cylindrical, sessile, apex flattened, with J- apical ring. Ascospores uniseriate, 1-septate, ellipsoidal, hyaline, turning brown and verruculose with age. Asexual morph: usually hyphomycetous. Conidiophores branched or unbranched, penicillate, verticillate. Conidiogenous cells branched, polyphialidic; phialides doliiform, cymbiform or cylindrical, aseptate, hyaline, with collarettes. Conidia aseptate to 1-septate, cylindrical, straight to curved, forming yellow mass on conidiophores (adapted from Lombard & Crous 2012).
Type species: Gliocladiopsis sagariensis S.B. Saksena, Mycologia 46: 662 (1954)
Notes: A new isolate MFLUCC 19-0309 in Hyde et al. (2020) grouped with the ex-type of Gliocladiopsis tenuis (IMI 68205) and other G. tenuis isolates (data not shown). The new isolate is also similar to G. tenuis in conidiophore and conidial dimensions (Crous & Wingfield 1993, Crous & Peerally 1996). Based on morphological similarities and phylogenetic analysis Hyde et al. (2020) identified the fungus as Gliocladiopsis tenuis, which is illustrated in this entry.
