2012). Felsenstein (2004) suggested that the Bayesian methods are closely related to the likelihood methods, differing only in the use of a prior distribution of the quantity being inferred, which would typically be the tree. Go6983 supplier Maximum parsimony analysis
has been shown to be a better method for establishing taxonomy at the family, genus and species levels. In our molecular data analysis, some of the new species taxonomic positions were not consistent when using the different methods. For example Auerswaldia lignicola clustered in the Diplodia / Lasiodiplodia clade in both Mr. Bayes and RAxML analysis, but with the Dothiorella/Spencermartinsia clade when using the Maximum Parsimony (MP) method. Furthermore, this only occurred
in the combined multi-gene (LSU, SSU, EF1-α and β-tubulin) analysis, however when combined EF1-α ABT-737 mouse and β-tubulin analysis was carried out they always clustered in the Dothiorella / Spencermartinsia clade. Maximum Parsimony may therefore be a better method for resolving the phylogeny and taxonomy in Botryosphaeriales. We also recommend that LSU, EF1-α, β-tubulin and RPB2 genes should be sequenced for differentiating Wortmannin price genera, while the latter three genes can resolve cryptic species. Genera accepted in Botryosphaeriales Von Arx and Müller (1954) included 15 genera in Botryosphaeriaceae (Table 2). This study suggests that Auerswaldia, Auerswaldiella, Botryosphaeria, Pyrenostigme and Vestergrenia were correctly placed in the family, indicating that von Arx and Müller (1954) were
remarkably astute in their understanding and observations. Many of the genera that von Arx and Müller (1954) included were subsequently removed from Botryosphaeriaceae by various researchers (Table 2) and in Lumbsch and Huhndorf (2010) only 11 genera were listed for the order. Bagnisiella is presently included Carbohydrate in Dothideaceae (Lumbsch and Huhndorf 2010) as discussed above under Auerswaldia. Cleistosphaeria as represented by C. macrostegia Syd. & P. Syd. is presently included in Parodiopsidaceae (Lumbsch and Huhndorf 2010). The ascospores are unicellular and typical of Botryosphaeriaceae, whereas the asci are unusual in being widely clavate and ascomata have a peridium comprising a single cell layer (S. Boonmee, pers. obs.). Montagnellina is now considered a synonym of Phyllosticta (= Guignardia) (Wikee et al. 2011a; Wong et al. 2012). Muyocopron is typical of Botryosphaeriaceae but the almost thyriothecoid ascomata are atypical and molecular data of Wu et al. (2011) exclude this genus. Ellisiodothis is treated as a synonym of Muyocopron in Index Fungorum, while Microdothella as represented by M. culmicola Syd. & P. Syd. is also probably a synonym. Trabutia is a synonym of Phyllachora (Barr 1987), while we have not been able to examine Pilgeriella. In the present study, we include 29 genera in Botryosphaeriales; this includes several genera (i.e.
