The name reflects its morphological similarity of the type species to the asexual morphs of Bambusicola and Neobambusicola.

Type species.

Pseudobambusicola thailandica Hern.-Restr. & Crous.

Diagnosis.

Differs from Neobambusicola in having conidiomata with a neck, the presence of globose to subglobose thick-walled cells adjacent to the conidiomata and the production of chlamydospores in culture.

Mycelium composed of hyaline to pale brown, septate, smooth to slightly verruculose, hyphae. Conidiomata pycnidial, semi- or entirely immersed in the agar, solitary or aggregated, erumpent, globose with a neck, opening via central ostiole, dark brown, surrounded by dark brown, smooth to slightly verruculose hyphae, at the base globose to subglobose, thick-walled cells often present. Conidiophores reduced to conidiogenous cells. Conidiogenous cells phialidic with periclinal thickening at the conidiogenous locus, subcylindrical to ampulliform, hyaline, smooth. Conidia exposed in white, mucous drops at the ostioles of the pycnidia, composed by macro- and microconidia. Macroconidia produced in white, mucous heads, solitary, fusoid-ellipsoid, apex bluntly to subobtusely rounded, tapering to a distinctly truncate base, prominently guttulate, hyaline, smooth, 0–3-septate. Microconidia produced in the same pycnidia as macroconidia, solitary, oblong to cuneiform, non-guttulate to slightly guttulate, hyaline, smooth, aseptate. Chlamydospores brown, terminal at the tips of vegetative hyphae, in chains. Sexual morph not observed.
