Dyfrolomycetales with the type genus Dyfrolomyces was introduced to accommodate marine fungi and now includes terrestrial, wood-inhabiting taxa which are characterized by immersed, ostiolate, clypeate, papillate ascomata, bitunicate, cylindrical, short pedicellate asci, with a distinct ocular chamber along with a ring-like subapical ring, and overlapping uni-seriate, broadly fusiform, symmetrical, hyaline, multi-septate ascospores. Only the single family Pleurotremataceae is accepted in this order. The divergence time for Dyfrolomycetales is estimated as 171 MYA (stem age, Hongsanan et al. 2020) (Fig. 29).
Accepted families: Pleurotremataceae.
Fig. 29 Phylogram generated from maximum likelihood analysis (RAxML) of Dyfrolomycetales based on LSU and SSU sequence data. Maximum likelihood bootstrap values equal or above 70%, Bayesian posterior probabilities equal or above 0.90 (MLBS/PP) are given at the nodes. An original isolate number is noted after the species name. The tree is rooted to Anisomeridium phaeospermum (MPN539) and A. ubianum (94). The ex-type and reference strains are indicated in bold. Hyphen (-) represents sup- port values below 70% MLBS and 0.90 PP
