“…Characters shared by the teleomorphic species of this order include dimorphism, mycoparasitism and tremelloid haustorial cells subtended by clamp connections (Bandoni 1998). Mycogloea does not appear monophyletic with these data (SUPPLEMENTARY FIG.…”

In this study we provide a phylogenetically based introduction to the classes and orders of Pucciniomycotina (5Urediniomycetes), one of three subphyla of Basidiomycota. More than 8000 species of Pucciniomycotina have been described including putative saprotrophs and parasites of plants, animals and fungi. The overwhelming majority of these (,90%) belong to a single order of obligate plant pathogens, the Pucciniales (5Uredinales), or rust fungi. We have assembled a dataset of previously published and newly generated sequence data from two nuclear rDNA genes (large subunit and small subunit) including exemplars from all known major groups in order to test hypotheses about evolutionary relationships among the Pucciniomycotina. The utility of combining nuc-lsu sequences spanning the entire D1-D3 region with complete nuc-ssu sequences for resolution and support of nodes is discussed. Our study confirms Pucciniomycotina as a monophyletic group of Basidiomycota. In total our results support eight major clades ranked as classes (Agaricostilbomycetes, Atractiellomycetes, Classiculomycetes, Cryptomycocolacomycetes, Cystobasidiomycetes, Microbotryomycetes, Mixiomycetes and Pucciniomycetes) and 18 orders.

“…5 ). The species of Mycogloea shared some phenotypic characters with those of Spiculogloea , including the presence of dimorphism, mycoparasitism and presence of tremelloid haustorial cells subtended by clamp connections ( Bandoni 1998 ). However, previous molecular analyses ( Aime et al., 2006 , Aime et al., 2014 , Bauer et al., 2006 ) and this study ( Fig.…”

“…5 ). The three anamorphic Kurtzmanomyces species including the type species of this genus formed a distinct clade closely related to the teleomorphic species Mycogloea nipponica that forms auricularioid basidia ( Bandoni 1998 ). Though the latter has a Kurtzmanomyces -like state, the connection between Kurtzmanomyces and M. nipponica needs to be addressed further as discussed in Sampaio (2011b) .…”

“…Though the latter has a Kurtzmanomyces -like state, the connection between Kurtzmanomyces and M. nipponica needs to be addressed further as discussed in Sampaio (2011b) . The original description of M. nipponica based on a Japanese collection did not include a living culture ( Bandoni 1998 ). The culture from which molecular data were obtained was isolated from a collection made in Taiwan ( Kirschner et al.…”

“…2003 ). It is not clear whether the Kurtzmanomyces species have a sexual Mycogloea -like stage and if the remaining five Mycogloea species ( Bandoni 1998 ) have a Kurtzmanomyces -like yeast stage. The present and previous ( Aime et al., 2006 , Aime et al., 2014 , Bauer et al., 2009 ) studies indicate that the genus Mycogloea is polyphyletic and species of this genus occur in the Agaricostibales and Spiculogloeales .…”

In addition to rusts, the subphylum Pucciniomycotina (Basidiomycota) includes a large number of unicellular or dimorphic fungi which are usually studied as yeasts. Ribosomal DNA sequence analyses have shown that the current taxonomic system of the pucciniomycetous yeasts which is based on phenotypic criteria is not concordant with the molecular phylogeny and many genera are polyphyletic. Here we inferred the molecular phylogeny of 184 pucciniomycetous yeast species and related filamentous fungi using maximum likelihood, maximum parsimony and Bayesian inference analyses based on the sequences of seven genes, including the small subunit ribosomal DNA (rDNA), the large subunit rDNA D1/D2 domains, the internal transcribed spacer regions (ITS 1 and 2) of rDNA including the 5.8S rDNA gene; the nuclear protein-coding genes of the two subunits of DNA polymerase II (RPB1 and RPB2) and the translation elongation factor 1-α (TEF1); and the mitochondrial gene cytochrome b (CYTB). A total of 33 monophyletic clades and 18 single species lineages were recognised among the pucciniomycetous yeasts employed, which belonged to four major lineages corresponding to Agaricostilbomycetes, Cystobasidiomycetes, Microbotryomycetes and Mixiomycetes. These lineages remained independent from the classes Atractiellomycetes, Classiculomycetes, Pucciniomycetes and Tritirachiomycetes formed by filamentous taxa in Pucciniomycotina. An updated taxonomic system of pucciniomycetous yeasts implementing the ‘One fungus = One name’ principle will be proposed based on the phylogenetic framework presented here.
