Conidia holoblastica, ellipsoidea, apice obtuso et basi hilo plano protrudente, continua. Ascomata perithecial, immersed in host tissue, oblique to horizontal, depressed globose or elliptical, dark brown to black; beak usually erumpent epiphyllously, eccentric to lateral; ostiole lined with periphyses; peridium coriaceous, with sparse hyphae visible growing into the host tissue; stromatic tissue not Inhibitor Library cost formed. Asci subcylindrical to long obovoid,

lacking paraphyses, unitunicate, with non-amyloid subapical ring, wedge-shaped, refractive, with canal Belnacasan leading to the apex. Ascospores hyaline, ellipsoidal, tapering towards rounded ends, usually straight, medianly 1-septate, wall smooth, with terminal, elongate, hyaline appendages.

Conidiomata acervular to pycnidial, subcuticular to epidermal, wall composed of textura angularis. Conidiophores absent. Conidiogenous cells cylindrical to ampulliform, proliferating enteroblastically with periclinal thickening and collarette, or percurrently proliferating in the apical part. Conidia holoblastic, ellipsoid, with obtuse apex and a flat protruding scar at the base, 0-septate. Type species: Pseudoplagiostoma eucalypti Cheewangkoon, M.J.
