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

Parasitic on living leaves and twigs. Sexual morph: Ascomata scattered, black, oval to almost sphaerical, immersed in the leaf tissue beneath a thin, well-developed clypeus, without a neck or only slightly papillate, periphysate. Peridium comprising 5–6 outer layers of dark, thick-walled cells of textura angularis and inner, thin-walled, strongly flattened cells of textura angularis. Paraphyses not seen. Asci 8-spored, unitunicate, short-pedicellate, blunt at the apex with a J-, apical ring. Ascospores 1–2-seriate, elliptical to fusoid, often slightly flattened on one side, unicellular, hyaline. Asexual morph: Coelomycetous. Stroma loculate, globose to irregular, sometimes with beaks. Conidiogenous cells phialidic, short to elongate, simple or branched. Conidia oblong or cylindrical to allantoid, 1-celled, hyaline (adapted from Senanayake et al. 2017a).

Notes – Apiosporopsidaceae was introduced by Senanayake et al. (2017a) to accommodate Apiosporopsis species which are morphologically distinct from other families in Diaporthales. The asci initially form a hymenium-like fascicle within a papillate ascomata, asci have a bilobed apical ring and residual stromatic tissue is present within the locules. This family is supported by molecular data (Braun et al. 2018, Fan et al. 2018, Senanayake et al. 2017a, 2018, Tian et al. 2018).

Type genus: Apiosporopsis (Traverso) Mariani, Atti Soc. ital. Sci. nat. Mus. Civico Storia nat. Milano 50: 165 (1911)
