Type species:Muyocopron corrientinumSpeg.

Notes:Muyocopron was introduced by Spegazzini (1881), with the type speciesM. corrientinum. Saccardo (1883) re-described this genus and placed it inMicrothyriaceae.Muyocopronwas synonymized underEllisiodothisby von Arx and Müller (1954). Later, it was transferred toBotryosphaeriaceaeandMicrothyriaceae(von Arx and Müller 1975; Lumbsch and Huhndorf 2007, 2010). However,Muyocoprondiffers from members ofMicrothyriaceaeby pseudothyriothecia with the peridial wall comprising two layers, pseudoparaphyses longer than the asci, and aseptate ascospores (Hyde et al. 2013; Mapook et al. 2016b). Molecular studies indicated thatMuyocopronis distantly related to theMicrothyriaceae(Wu et al. 2011a, b; Mapook et al. 2016b, and Fig. 56). The genus clustered withDyfrolomycetaceae(Dyfrolomycetales), but as a distinct order (Hyde et al. 2013; Mapook et al. 2016b).

Fig. 56Phylogram 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 toAcrospermum compressum(M151) andA. gramineum(M152). The ex-type strains are indicated in bold. Hyphen (-) represents support values below 70% MLBS and 0.90 PP
