Bottom Line: The treated species include three new genera, Bagadiella, Foliocryphia and Pseudoramichloridium, 20 new species and one new combination.Novelties on Eucalyptus include: Antennariella placitae, Bagadiellalunata, Cladoriella rubrigena, C. paleospora, Cyphellophora eucalypti, Elsinoë eucalypticola, Foliocryphia eucalypti, Leptoxyphium madagascariense, Neofabraea eucalypti, Polyscytalum algarvense, Quambalaria simpsonii, Selenophoma australiensis, Sphaceloma tectificae, Strelitziana australiensis and Zeloasperisporium eucalyptorum.Stylaspergillus synanamorphs are reported for two species of Parasympodiella, P. eucalypti sp. nov. and P. elongata, while Blastacervulus eucalypti, Minimedusa obcoronata and Sydowia eucalypti are described from culture.Furthermore, Penidiella corymbia and Pseudoramichloridium henryi are newly described on Corymbia, Pseudocercospora palleobrunnea on Syzygium and Rachicladosporium americanum on leaf litter.

ABSTRACT
Twenty-six species of microfungi are treated, the majority of which are associated with leaf spots of Corymbia, Eucalyptus and Syzygium spp. (Myrtaceae). The treated species include three new genera, Bagadiella, Foliocryphia and Pseudoramichloridium, 20 new species and one new combination. Novelties on Eucalyptus include: Antennariella placitae, Bagadiellalunata, Cladoriella rubrigena, C. paleospora, Cyphellophora eucalypti, Elsinoƫ eucalypticola, Foliocryphia eucalypti, Leptoxyphium madagascariense, Neofabraea eucalypti, Polyscytalum algarvense, Quambalaria simpsonii, Selenophoma australiensis, Sphaceloma tectificae, Strelitziana australiensis and Zeloasperisporium eucalyptorum.Stylaspergillus synanamorphs are reported for two species of Parasympodiella, P. eucalypti sp. nov. and P. elongata, while Blastacervulus eucalypti, Minimedusa obcoronata and Sydowia eucalypti are described from culture. Furthermore, Penidiella corymbia and Pseudoramichloridium henryi are newly described on Corymbia, Pseudocercospora palleobrunnea on Syzygium and Rachicladosporium americanum on leaf litter. To facilitate species identification, as well as determine phylogenetic relationships, DNA sequence data were generated from the internal transcribed spacers (ITS1, 5.8S nrDNA, ITS2) and the 28S nrDNA (LSU) regions of all taxa studied.

One of 27 equally most parsimonious trees obtained from a heuristic search with 100 random taxon additions of the LSU sequence alignment using PAUP v4.0b10. The scale bar shows 10 changes, and bootstrap support values higher than 70 % from 1 000 replicates are shown at the nodes. Thickened lines indicate the strict consensus branches and novel sequences are printed in bold. The tree was rooted to Saccharomyces cerevisiae (GenBank accession Z73326). AGA = Agaricomycetes, EXO = Exobasidiomycetes, EUR = Eurotiomycetes, LEO = Leotiomycetes, SOR = Sordariomycetes, DOT = Dothideomycetes, all others are incertae sedis.

Mentions: The manually adjusted LSU alignment contained 98 taxa (including the outgroup sequence) and, of the 479 characters used in the phylogenetic analysis, 294 were parsimony-informative, 33 were variable and parsimony-uninformative and 152 were constant. Twenty-seven equally most parsimonious trees were obtained from the heuristic search, the first of which is shown in Fig. 1 (TL = 1831, CI = 0.356, RI = 835, RC = 297). The phylogenetic tree of the LSU region (Fig. 1) showed the isolates obtained in this study to cluster in several classes, including Agaricomycetes, Exobasidiomycetes, Eurotiomycetes, Sordariomycetes and Dothideomycetes. Further results are discussed under the species notes below where applicable.
