Type species – Diaporthosporella cercidicola C.M. Tian & Q. Yang

Notes – Diaporthosporella was introduced by Yang et al. (2018d). Diaporthosporella cercidicola is characterized by hyaline, allantoid or sub-reniform, aseptate ascospores and acropleurogenous, branched or sympodially branched conidiophores, producing hyaline, ellipsoidal, aseptate and biguttulate conidia (Yang et al. 2018d). Diaporthosporella comprises a single species found on branches and twigs of Cercis chinensis in China (Yang et al. 2018d). 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. 2018d). 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. 2018d). Diaporthosporella cercidicola is closely related to Juglanconidaceae according to molecular phylogeny (Voglmayr et al. 2017).
