Pseudocoleophoma

Pseudocoleophoma Kaz. Tanaka & K. Hiray., Stud. Mycol. 82: 89 (2015)

 

Saprobic on decaying pod, leaves, stems and submerged wood. Sexual morph: Ascomata scattered or gregarious, immersed to erumpent, globose to subglobose, ostiolate. Ostiolar neck central, composed of subglobose, dark brown cells. Peridium composed of several layers of polygonal to rectangular cells. Pseudoparaphyses numerous, cellular, hypha-like, septate, branched, anastomosing. Asci 8-spored, bitunicate, fissitunicate, cylindrical to clavate, short pedicellate. Ascospores fusiform, septate, smooth, with a conspicuous, mucilaginous sheath (Tanaka et al. 2015). Asexual morph: Coelomycetous. Conidiomata immersed to erumpent, subglobose. Ostiolar neck well-developed, cylindrical, central. Peridium composed of several layers of slightly thick-walled, pale brown, polygonal to subglobose cells. Conidiophores absent. Conidiogenous cells enteroblastic, phialidic, doliiform to lageniform. Conidia cylindrical, hyaline, aseptate or septate, smooth (Tanaka et al. 2015).

 

Type species: Pseudocoleophoma calamagrostidis Kaz. Tanaka & K. Hiray.

 

Notes: Pseudocoleophoma is characterized by fusiform, septate ascospores with conspicuous sheath and coleophoma-like conidia (Tanaka et al. 2015). Pseudocoleophoma was placed in Dictyosporiaceae based on molecular data (Tanaka et al. 2015; Boonmee et al. 2016; Yang et al. 2018). Four species are listed in Index Fungorum (2020). Pseudocoleophoma typhicola Kamolhan et al. (Hyde et al. 2016) is known from only an asexual morph, while the other species have both sexual and asexual morphs. Pseudocoleophoma typhicola is the only species producing septate conidia (Tanaka et al. 2015; Hyde et al. 2016; Jayasiri et al. 2019).
