Maharachchkumbura et al. (2016b) established the subclass Lulworthiomycetidae to accommodate Koralionastetales, Lulworthiales and Pisorisporiales as proposed by Maharachchikumbura et al. (2015). Taxa related to Lulworthiomycetidae are saprobic on wood, sea grasses and marsh plants or parasites on algae. The divergence time for Lulworthiomycetidae has been estimated as 257 MYA (Fig. 2). Currently there are two orders and two families in this subclass and Pisorisporiales is transferred to the introduced subclass Pisorisporiomycetidae in this study.

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).
