Maharachchikumbura et al. (2016b) listed Magnaporthaceae, Ophioceraceae, and Pyriculariaceae in Magnaporthales based on the literature and phylogenetic analysis. Pseudohalonectriaceae was introduced as a novel family in Magnaporthales to accommodate Pseudohalonectria based on phylogenetic and molecular dating evidence (Hongsanan et al. 2017). The stem age of Pseudohalonectria falls within the range of family status (95 MYA) and has high support in the phylogenetic and MCC trees. Silva et al. (2019) introduced a new genus Bifusisporella, in Magnaporthaceae, to accommodate an endophytic fungus in Brazil. Hence, Magnaporthales comprises five families, Ceratosphaeriaceae, Magnaporthaceae, Ophioceraceae, Pseudohalonectriaceae, and Pyriculariaceae. The divergence time for Magnaporthales is estimated as 190 MYA (Fig. 2). Currently there are 36 genera in this order (this paper).
Figure 2 – The maximum clade credibility (MCC) tree, using the same dataset from Fig. 1. This analysis was performed in BEAST v1.10.2. The crown age of Sordariomycetes was set with Normal distribution, mean = 250, SD = 30, with 97.5% of CI = 308.8 MYA, and crown age of Dothideomycetes with Normal distribution mean = 360, SD = 20, with 97.5% of CI = 399 MYA. The substitution models were selected based on jModeltest2.1.1; GTR+I+G for LSU, rpb2 and SSU, and TrN+I+G for tef1 (the model TrN is not available in BEAUti 1.10.2, thus we used TN93). Lognormal distribution of rates was used during the analyses with uncorrelated relaxed clock model. The Yule process tree prior was used to model the speciation of nodes in the topology with a randomly generated starting tree. The analyses were performed for 100 million generations, with sampling parameters every 10000 generations. The effective sample sizes were checked in Tracer v.1.6 and the acceptable values are higher than 200. The first 20% representing the burn-in phase were discarded and the remaining trees were combined in LogCombiner 1.10.2., summarized data and estimated in TreeAnnotator 1.10.2. Bars correspond to the 95% highest posterior density (HPD) intervals. The scale axis shows divergence times as millions of years ago (MYA).
