Pleiochaeta
Pleiochaeta (Sacc.) S. Hughes, Mycol. Pap. 36: 39 (1951).
≡ Ceratophorum subgen. Pleiochaeta Sacc., Syll. fung. (Abellini) 11: 622 (1895).
Index Fungorum number: IF 9443; Facesoffungi number: FoF 07940, 6 morphological species (Species Fungorum 2021), 3 species with molecular data.
Pathogenic on host: Sexual morph: Unknown. Asexual morph: Conidiophores macronematous, mononematous or grouped in fascicles, simple, erect, straight to flexuous, or geniculate, hyaline to pale olivaceous, smooth. Conidiogenous cells mono- and polyblastic, integrated, terminal and intercalary, cylindrical. Conidia solitary, dry, sub cylindrical to fusoid, mostly curved, narrowed to obtuse at the apex, truncate at the base, pale to dark brown, smooth, multiseptate; apical cell bears several long, hyaline, subulate appendages which are sometimes branched. Chlamydospores present or absent, brown to dark brown in chains or in groups (adapted from Marin et al. 2017).
Type species: Pleiochaeta setosa (Kirchner) S. Hughes
Notes: Pleiochaeta was introduced by Hughes (1951) with P. setosa as type species. Pleiochaeta is characterized by micronematous conidiophores, mono- and polyblastic conidiogenous cells, dry, sub cylindrical to fusoid conidia sometimes presence of brown to dark brown chlamydospores. Marin-Felix et al. (2017) reported the position of Pleiochaeta in the Dothidotthiaceae based on LSU and ITS phylogenetic analysis.
