Sordariomycetidae, Chaetosphaeriales, Chaetosphaeriaceae, Codinaea

Index Fungorum number: IF 7720; 16 morphological species (Species Fungorum 2020), 4 species with sequence data.

 

Saprobic on wood or decaying plant parts. Asexual morph: Colonies on natural substrate black, scattered, hairy. Mycelium immersed or superficial, comprising brown, septate, branched, smooth-walled hyphae. Conidiophores macronematous, mononematous or synnematous, usually pale brown, septate. Conidiogenous cells mono- to polyphialidic, terminal, with flared collarette, determinate or indeterminate, with few sympodial extensions and at times with enteroblastic percurrent regenerations. Conidia hyaline, aseptate or septate, falcate to lunate, comprising a filiform appendage at both ends. Sexual morph: Undetermined (Luo et al. 2019).

 

 

Type species: Codinaea aristata Maire, Publ. Inst. Bot. Barcelona 3(no. 4): 15 (1937)

 

 

Notes: Codinaea was introduced based on C. aristata (Maire 1937). Gamundi et al. (1977) examined several specimens of Dictyochaeta fuegiana and proposed Codinaea as a synonym of Dictyochaeta. Their treatment was accepted by most authors and many Codinaea taxa have been moved to Dictyochaeta (Kirschner & Chen 2002, Cruz et al. 2008, Liu et al. 2016, Whitton et al. 2012). However, re-examination of the two collections, on which Gamundí et al. (1977) based their description of D. fuegiana (LPS 38629, LPS 38630), revealed a fungus was misidentified as the type of Dictyochaeta fuegiana (Réblová 2004). Réblová (2004) re-examined the type specimen of Dictyochaeta fuegiana and gave detailed descriptions. Molecular studies by Réblová & Winka (2000) revealed that Dictyochaeta species with or without setulae clustered into distinct subgroups in the phylogenetic tree. Réblová (2000) proposed to retain Codinaea for species with setulae and placed species without setulae in Dictyochaeta. Seifert et al. (2011) and Li et al. (2012) accepted Réblová (2000) suggestion on segregation of Codinaea and Dictyochaeta as separate genera delineated by the presence or absence of conidial setulae and accepted both Codinaea and Dictyochaeta as valid genera.

Wijayawardene et al. (2018) and Hernández-Restrepo (2017) also treated them as two distinct genera. Currently, 104 species of Dictyochaeta and 53 species of Codinaea have been described (Index Fungorum 2020). However, only few have DNA sequence data. There are no ex-type sequence data are available for the generic types of Codinaea or Dictyochaeta.  Phylogenetic analysis conducted by Hyde et al. (2020), based on the available sequences of Dictyochaeta and Codinaea species, revealed that species of both genera are polyphyletic within Chaetosphaeriaceae. Therefore, a detailed morpho-molecular analysis with more taxonomic sampling would be required to finally confirm the phylogenetic status of Codinaea and Dictyochaeta. Hyde et al. (2020) kept  Codinaea and Dictyochaeta as separate genera until the generic types of Codinaea and Dictyochaeta are recollected, sequenced and confirmed the link by molecular data.
