Pseudotracylla dentata B. Sutton & Hodges, Nova Hedwigia 27(3-4): 699. 1976. (Type species).
Conidiomata pycnothyrial, superficial, solitary to gregarious, circular, dark brown, composed of upper and lower walls connected by a central columella; upper wall composed of one layer of conidiogenous cells; lower wall membranous, dark brown. Conidiogenous cells phialidic, smooth, 4.5–8.5 × 3–4 μm, restricted to upper wall and facing down towards lower wall, with a minute collarette. Conidia fusiform to falcate, aseptate, hyaline, smooth, 9.5–12 × 3–4 μm. Sexual state unknown (Description from Sutton and Hodges Jr, 1976).
Typification: Holotype IMI196483K.
Gene sequences: Unknown.
Hosts/substrates: On leaves of Eucalyptus citriodora (Myrtaceae).
Distribution: Brazil.
