Pathogenic on branches and twigs of Cercis chinensis. Sexual morph: Ascomata perithecial, immersed to erumpent, globose to subglobose, dark brown to black, penetrating through ectostroma, convergent to disc. Paraphyses filiform, hyaline, unbranched, deliquescent at maturity. Asci 8-spored, unitunicate, clavate to oblong-clavate, floating freely in the centrum, apical ring become unclear in dried specimens. Ascospores irregularly uniseriate, allantoid or sub-reniform, 3-4-guttulate, hyaline, aseptate. Asexual morph: Coelomycetous. Conidiomata pycnidial, immersed, erumpent at maturity, globose to subglobose, yellowish conidial mass release from ostiole. Ectostromatic disc black, one ostiole for each disc. Conidiophores acropleurogenous, branched or sympodially branched, cylindrical, aseptate. Conidiogenous cells enteroblastic, phialidic, cylindrical, terminal, slightly tapering towards the apex. Conidia ellipsoidal, aseptate, hyaline, slightly rounded at each end (adapted from Yang et al. 2018d, Senanayake et al. 2018).
Notes – Diaporthosporellaceae was introduced by Yang et al. (2018d) to accommodate Diaporthosporella. Morphology and phylogeny of Diaporthosporellaceae is different from other families of Diaporthales. Diaporthosporellaceae is characterized by unicellular ascospores, branched or sympodially branched conidiophores, and hyaline, biguttulate conidia (Yang et al. 2018d, Senanayake et al. 2018). Diaporthosporellaceae comprises only one genus and one species. Diaporthosporellaceae was found on branches and twigs of Cercis chinensis (Fabaceae) in China. Sequence data are available in GenBank (Yang et al. 2018d, Fan et al. 2018).
