Pleomonodictydaceae Hern. - Restr., J. Mena & Gene

Pleomonodictydaceae Hern.- Restr., J. Mena & Gené, Stud. Mycol. 86: 76 (2017), amended Description. Saprobic on woody substrates in terrestrial and aquatic habitats. Sexual morph: Ascomata solitary or in groups, often growing under or in a pseudostroma, immersed, semi-immersed to erumpent, perithecial, brown to dark brown, ostiolate. Ostiolar neck papillate. Peridium multi-layered, outer layer usually fusing with the stroma or host tissue. Pseudoparaphyses hyaline, filiform, cellular. Asci bitunicate, 8 - spored, clavate to cylindric-clavate, pedicellate, with an ocular chamber. Ascospores 1–3 - seriate, fusiform to cylindrical, hyaline, septate, surrounded by a mucilaginous sheath. Asexual morph: hyphomycetous. See Hernández-Restrepo et al. (2017), Jayasiri et al. (2019), Bao et al. (2021) for further details. Type genus. Pleomonodictys Hern.-Restr., J. Mena & Gené Notes. Pleomonodictydaceae has so far accommodated the two hyphomycetous genera, Pleohelicoon and Pleomonodictys (Hernández-Restrepo et al. 2017; Jayasiri et al. 2019), whose sexual morphs are still undetermined. In the present study, Inflatispora and the novel genus, Robiniigena are accepted in the family based on the combined SSU – LSU – ITS – tef 1 - α – rpb 2 phylogenetic analyses (Fig. 1). Since both genera are known in their sexual morphs, the description of Pleomonodictydaceae is amended to include their sexual morphological characteristics.
