Notes.

Microthyriales only contains a single family Microthyriaceae , based on morphology and phylogeny. Currently, eleven genera are accepted in Microthyriaceae , including three asexual genera ( Hongsanan et al. 2020; Wijayawardene et al. 2020). The asexual morph of this family is characterised by having micronematous or macronematous, unbranched or branched, septate conidiophores, mono- to polyblastic, determinate or sympodial, clavate, subcylindrical, ampulliform or ovoid conidiogenous cells and solitary or in branched chains, acrogenous or acropleurogenous, aseptate to multi-septate conidia. In this study, we erected two new asexual genera, Antidactylaria and Isthmomyces and recognised six new asexual species in Microthyriaceae , based on DNA sequences at two gene fragments. In addition, two new combinations are proposed in Microthyriaceae combined morphology and phylogeny.
