A phylogenetic analysis of the concatenated alignment was performed on CIPRES webportal (Miller et al. 2009) using RAxML v. 7.2.7 (Stamatakis 2006; Stamatakis et al. 2008) applying unique model parameters for each gene and codon (8 partitions). A general time reversible model (GTR) was applied with
a discrete gamma distribution and four rate Adriamycin classes. Fifty thorough maximum likelihood (ML) tree searches were done in RAxML v. 7.2.7 under the same model, each one starting from a separate randomized tree and the best scoring tree selected with a final likelihood value of −95238.628839. Two isolates of Hysterium angustatum (Hysteriales, Pleosporomycetidae) were used as outgroups based on earlier work (Boehm et al. 2009a). Bootstrap pseudo-replicates were run with the GTRCAT model approximation, allowing the program to halt PI3K Inhibitor Library cell line bootstraps automatically under the majority rule criterion (Pattengale et al. 2010). The resulting 250 replicates were plotted on to the best scoring tree obtained previously. The phylogram with bootstrap values on the branches is presented in Plate 1 by using graphical options available in TreeDyn v. 198.3 (Chevenet et al. 2006). Morphology Type specimens as well as some other specimens were loaned from the following herbaria: BAFC, BISH, BPI, BR, BRIP, CBS, E, ETH, FFE, FH, G, H, Herb. J. Kohlmeyer, HHUF, IFRD, ILLS, IMI, K(M), L, LPS, M, MA, NY, PAD, PC, PH, Tolmetin RO, S, TNS, TRTC, UB, UBC, UPS and ZT. Attempts were made to trace and borrow all the type specimens from herbaria worldwide, but only some of them could be obtained. Some of the type specimens are in such
bad condition that little information could be obtained. In order to obtain the location of specimens, original publications were searched. Ascostroma and ascomata were examined under an Olympus SZ H10 dissecting microscope. Section of the fruiting structures was carried out by cryotome or by hand-cutting. Measurements and descriptions of sections of the ascomata, hamathecium, asci and PXD101 mouse ascospores were carried out by immersing ascomata in water or in 10% lactic acid. Microphotography was taken with material mounted in water, cotton blue, Melzer’s reagent or 10–100% lactic acid. Terminologies are as in Ulloa and Hanlin (2000). In addition, ascomata size is defined as: small-sized: < 300 μm diam.
