We present a comprehensive phylogeny derived from 5 genes, nucSSU, nucLSU rDNA, TEF1, RPB1 and RPB2, for 356 isolates and 41 families (six newly described in this volume) in Dothideomycetes. All currently accepted orders in the class are represented for the first time in addition to numerous previously unplaced lineages. Subclass Pleosporomycetidae is(More)
A new pleosporalean family Tetraplosphaeriaceae is established to accommodate five new genera; 1) Tetraplosphaeria with small ascomata and anamorphs belonging to Tetraploa s. str., 2) Triplosphaeria characterised by hemispherical ascomata with rim-like side walls and anamorphs similar to Tetraploa but with three conidial setose appendages, 3)(More)
We here taxonomically revise the suborder Massarineae (Pleosporales, Dothideomycetes, Ascomycota). Sequences of SSU and LSU nrDNA and the translation elongation factor 1-alpha gene (tef1) are newly obtained from 106 Massarineae taxa that are phylogenetically analysed along with published sequences of 131 taxa in this suborder retrieved from GenBank. We(More)
During an investigation of Hypocrea/Trichoderma species inhabiting mushroom bedlogs, we found five strains of an undescribed species from a culture collection. These were analyzed using a combined approach, including morphology of holomorph, cultural studies, and phylogenetic analyses of the rRNA gene cluster of the internal transcribed spacer region,(More)
We analyzed the DNA sequences of four gene regions, 28S and 18S rDNA, the ITS region and rpb2, to obtain a high resolution phylogenetic tree of Dacrymycetes. In addition, we comparatively studied micro- and macromorphological characteristics of representative species. The traditional generic classification based on morphological characteristics was not(More)
A new anamorphic fungus, Beltraniella botryospora, is described and illustrated with line drawings and photographs. This fungus was isolated frequently from living and fallen leaves of Quercus acuta, but rarely or never from other evergreen oaks and Castanopsis sieboldii grown at the same investigation site, suggesting that this new fungus might have strong(More)
Evolution of lignocellulose decomposition was one of the most ecologically important innovations in fungi. White-rot fungi in the Agaricomycetes (mushrooms and relatives) are the most effective microorganisms in degrading both cellulose and lignin components of woody plant cell walls (PCW). However, the precise evolutionary origins of lignocellulose(More)
Trichoderma eijii and T. pseudolacteum, are described here as new species from Japan. These species were isolated from decaying wood in the Tomakomai Experimental Forest in Hokkaido Prefecture and from bedlogs on shiitake mushroom (Lentinula edodes) farms, respectively. The species were characterized using a combined approach that included cultural studies,(More)
A Dacryopinax species that was cultured in Costa Rica and fruited in the laboratory provided DNA for the first sequenced genome for the Dacrymycetes. Here we characterize the isolate morphologically and cytologically and name it D. primogenitus Molecular sequences from the nuclear large subunit gene and internal transcribed spacer indicated that it is(More)
