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, biguttulate (adapted from Yang et al. 2018, Senanayake et al. 2018).


Type species: Diaporthosporella cercidicola C.M. Tian & Q. Yang, in Yang, Fan, Du & Tian, Mycoscience 59(3): 234 (2018)


Notes: Diaporthosporella comprises a single species found on branches and twigs of Cercis chinensis in China (Yang et al. 2018). Diaporthosporella cercidicola is similar to Diaporthe eres Nitschke in having unitunicate, clavate asci, hyaline, guttulate ascospores, but can be separated by phylogeny (Yang et al. 2018). The asexual morph produces a yellowish conidial mass and aseptate, hyaline conidia, characters that are common to both Diaporthosporella cercidicola and Diaporthe eres (Udayanga et al. 2014, Yang et al. 2018). Diaporthosporella cercidicola is closely related to Juglanconidaceae according to molecular phylogeny (Voglmayr et al. 2017).
