Annulatascaceae represents an assemblage of many genera that are characterized by unilocular ascomata with a neck, cylindrical asci with a massive, J-, refractive, cylindrical to flaring, doughnut-shaped, apical ring and mostly fusiform, hyaline ascospores (Hyde et al. 2020). Maharachchikumbura et al. (2016) accepted 20 genera in the family and some were later transferred to other families or Diaporthomycetidae genera incertae sedis based on molecular data (Zhang et al. 2017, Réblová et al. 2018, Luo et al. 2019). For example, Dictyosporella, which has annulatascaceae-like sexual morph and helicoid conidia, was first transferred to Diaporthomycetidae genera incertae sedis together with an annulatascaceae-like sexual morph (Zhang et al. 2017), and now is placed in Junewangiaceae based on strong molecular evidence (Luo et al. 2019); Diluviicola, which has cylindrical asci with a large apical ring and fusiform ascosporers with polar caps, was transferred to Pseudoproboscisporaceae (Zhang et al. 2017); Pseudoannulatascus, which has ascomata with a long neck, cylindrical asci with a large apical ring, and long fusiform ascospores with sheaths, was transferred to Xenospadicoidaceae (Réblová et al. 2018). These excluded genera imply that several morphological characteristics, e.g. cylindrical asci with a relatively massive, refractive apical ring and fusiform ascospores, are not detailed enough to classify Annulatascaceae taxa.
