Type speciesMycopepon guianensis Boise, Syst. Ascom. 6(1): 168 (1987).

Notes – Recent phylogenetic study showed that Mycopepon fell into Astrosphaeriellaceae with two new species reported (Liu et al. 2018b). In our phylogenetic result (Fig. 53), Mycopepon also clustered in Astrosphaeriellaceae clade. From morphology, Mycopepon is within Astrosphaeriellaceae owing to superficial carbonaceous ascostromata, trabeculate pseudoparaphyses and fusoid ascospores with septa (Liu et al. 2018b). Mycopepon is distinguished from other genera of Astrosphaeriellaceae in 2–8 pseudothecial ascostroma. In this study, we follow Liu et al. (2018b) and treat Mycopepon as a member of Astrosphaeriellaceae

Figure 53 – Phylogram generated from maximum likelihood analysis (RAxML) of genera in Astrosphaeriellaceae based on LSU, rpb-2, SSU and tef1 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 Delitschia chaetomioides (SHM 3253.2) and D. winteri (AFTOL-ID 1599). The ex-type strains are indicated in bold. Newly sequence is in blue. Hyphen (-) represents support values below 70 % MLBS and 0.90 PP.
