Classification: Diaporthales, Diaporthomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Endophytic, saprobic or pathogenic on plants. Sexual morph: Undetermined. Asexual morph: Coelomycetous. Conidiomata stromatic or eustromatic, subepidermal to immersed, solitary to gregarious, subglobose to irregular, unilocular, pale brown. Conidiomata wall outer layer composed of thin-walled, pale brown cells of textura angularis, with inner layer of pale yellow to hyaline cells. Conidiophores hyaline, septate, cylindrical, and sparingly branched or reduced to conidiogenous cells. Conidiogenous cells holoblastic, annellidic, cylindrical, lageniform to ampulliform, hyaline, smooth, invested in mucus. Conidia obclavate, conical, aseptate, pale brown, with a longitudinal band on the flat surface, thick- and smooth-walled, guttulate, with short hyaline apiculus, with small globule of mucus on base or obtuse apex with a scar at the base (adapted from Senanayake et al. 2017a).

Notes – Apoharknessiaceae was introduced by Senanayake et al. (2017a) to accommodate Apoharknessia and Lasmenia. Lasmenia was previously assigned to Cryphonectriaceae (Maharachchikumbura et al. 2015, 2016b). However, available sequence data in GenBank for Lasmenia are not identified at the species level, thus, Wijayawardene et al. (2016b) placed Lasmenia in Diaporthales genera incertae sedis. However, phylogenetic analysis by Senanayake et al. (2017a) indicates that Apoharknessia and Lasmenia clearly belong in Diaporthales forming a well-supported clade.

Type genus: Apoharknessia Crous & S.J. Lee, Stud. Mycol. 50(1): 239 (2004).
