Muyocopronales Mapook, Boonmee & K.D. Hyde.
MycoBank number: MB 551615; Index Fungorum number: IF 551615; Facesoffungi number: FoF 01886.
This order was established by Mapook et al. (2016b) to accommodate a single family, Muyocopronaceae. The order formed a distinct clade within Dothideomycetes and was related to Acrospermales and Dyfrolomycetales (Mapook et al. 2016b; this study). Muyocopronales differs from Acrospermales and Dyfrolomycetales by superficial, flattened, carbonaceous, brittle ascomata, cellular pseudoparaphyses that are longer than the asci and ellipsoidal to ovate, unicellular ascospores (Hyde et al. 2013; Mapook et al. 2016b). Our phylogenetic analyses indicate that the order comprises a single family, Muyocopronaceae. Palawaniaceae is sister to the clade of Muyocopronaceae (81% ML, Fig. 56). Thus, we do not include this family within Muyocopronales. Currently there is one family with seven accepted genera in this order (this paper). The divergence time for Muyocopronales is estimated as 171 MYA (stem age, Hongsanan et al. 2020).
Accepted families: Muyocopronaceae.
Fig. 56 Phylogram generated from maximum likelihood analysis (RAxML) of Muyocopronales based on ITS, 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 Acrospermum compressum (M151) and A. gramineum (M152). The ex-type strains are indicated in bold. Hyphen (-) represents support values below 70% MLBS and 0.90 PP
