Index Fungorum, Facesoffungi, MycoBank, GenBank

Classification: Incertae sedis, Microascales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Etymology: refers to its similarity to the genus Codinaea.

Colonies effuse, superficial, brown. Anamorph: Conidiophores solitary to aggregated, erect or flexuous, branched at the apex, septate, brown, smooth. Conidiogenous cells integrated, determinate, ampulliform, lageniform, obclavate, pale brown to brown, with a deep, cylindrical or subcylindrical collarette. Conidia holoblastic, cylindrical, hyaline, aseptate, smooth, truncate at both ends, extruded in long chain. Teleomorph: Unknown.

Ecology/Substrate/Host: Saprobe on dead material of plants.

Geographical distribution: Brazil, Japan, Europe.

Description and illustration: Kendrick (1961); Matsushima (1975); Barbosa et al. (2009).

Notes: Morphologically it is difficult to be distinguished from Sporendocladia and Phialocephala, but the phylogenetic analysis shows that Phialocephala bactrospora belongs to Microascales, while the type species of genus Phialocephala W.B. Kendr., P. dimorphospora W.B. Kendr., belongs to Mollisiaceae in Helotiales; and the type species of Sporendocladia, S. fumosa, belongs to Chaetosphaeriaceae (Wingfield et al. 1987; Mouton and Wingfield 1993; Jacobs et al. 2001, 2003; Day 2012; Seifert et al. 2011; Roux et al. 2013; Tanney et al. 2016). Thus, a new genus, Parasporendocladia W.P. Wu & Y.Z. Diao, is created to accomendate Phialocephala bactrospora. Morphologically it is also similar with Custingophora, but phylogenetically different.

Type species: Parasporendocladia bactrospora (W.B. Kendr.) W.P. Wu & Y.Z. Diao (≡ Phialocephala bactrospora W.B. Kendr.). 

Other accepted species: Species Fungorum – search Parasporendocladia.
