“…We analyzed the single-locus data sets within a maximum likelihood (ML) framework (Mason-Gamer and Kellogg 1996; Reeb et al 2004) and the combined data set using both ML and Bayesian approaches. The combined data set was partitioned by individual locus, nuclear 28S and 18S and mitochondrial 16S, in both ML and Bayesian analyses.…”

The genus Cheiromycina is one of the few genera of lichenized hyphomycetes for which no sexual reproductive stages have been observed. The genus includes species from boreal to temperate regions of the Northern Hemisphere where it is found growing on bark or wood. Congeners in Cheiromycina are characterized by a noncorticate thallus, nearly immersed in the substrate and presenting powdery unpigmented sporodochia, and containing chlorococcoid photobionts. The relationships of members of Cheiromycina with other fungi are not known. Here we inferred the phylogenetic placement of Cheiromycina using three loci (nuSSU, nuLSU, and mtSSU) representing C. flabelliformis, the type species for the genus, C. petri, and C. reimeri. Our results revealed that the genus Cheiromycina is found within the family Malmideaceae (Lecanorales) where members formed a monophyletic clade sister to the genera Savoronala and Malmidea. This phylogenetic placement and the relationships of Cheiromycina with other lichenized hyphomycetous taxa are here discussed.

“…The combinability of the single locus data sets was assessed by visual inspection of the individual bootstrap values (Mason-Gamer & Kellogg 1996;Wiens 1998). A conflict was considered significant when two data partitions supported conflicting monophyletic groups with ML bootstrap values b70% in both trees.…”

This is the published version of a paper published in The Lichenologist. Citation for the original published paper (version of record):Otálora, M A., Wedin, M. (2013) Collema fasciculare belongs in Arctomiaceae. The phylogenetic placement of Collema fasciculare (L.) F. H. Wigg, the most deviating species within Collema (Collemataceae, Lecanoromycetidae), was studied using maximum likelihood and Bayesian analysis of three molecular loci (mitochondrial SSU rDNA, and the protein-coding, nuclear RPB1 and MCM7 genes). Collema fasciculare belongs to Arctomiaceae (Ostropomycetidae) forming a strongly supported monophyletic group with members of Arctomia. The spores, paraphyses, asci and hymenial reactions in Collema fasciculare are similar to other Arctomia, but the ascoma ontogeny is somewhat different. Also C. leptosporum Malme, another species in the Fasciculare group, shows similarities with Arctomia regarding spores and asci. Arctomia is morphologically heterogeneous and the genus is in need of revision. Until then, the species of the Fasciculare group fit best in Arctomia s. lat. and the combinations Arctomia fascicularis (L.) Otálora & Wedin, Arctomia leptospora (Malme) Otálora & Wedin, Arctomia papuanarum (Degel.) Otálora & Wedin and Arctomia uviformis (Hue) Otálora & Wedin are proposed.

“…Preliminary MP analyses conducted on the five individual plastid regions yielded similar tree topologies (trees not shown). There was no conflict between well-supported clades (P70% JK or BS support; Mason-Gamer and Kellog, 1996;Zhang and Simmons, 2006;Zhang et al, 2012Zhang et al, , 2016Zhou et al, in press) in the individual analyses and thus the five plastid regions were combined into one dataset comprising 190 taxa and 3346 characters (Table 3).…”
