Abstract
Chaetomiaceae comprises phenotypically diverse species, which impact biotechnology, the indoor environment and human health. Recent studies showed that most of the traditionally defined genera in Chaetomiaceae are highly polyphyletic. Many of these morphology-based genera, such as Chaetomium, Thielavia and Humicola, have been redefined using multigene phylogenetic analysis combined with morphology; however, a comprehensive taxonomic overview of the family is lacking. In addition, the phylogenetic relationship of thermophilic Chaetomiaceae species with non-thermophilic taxa in the family is largely unclear due to limited taxon sampling in previous studies. In this study, we provide an up-to-date overview on the taxonomy and phylogeny of genera and species belonging to Chaetomiaceae, including an extensive taxon sampling of thermophiles. A multigene phylogenetic analysis based on the ITS (internal transcribed spacers 1 and 2 including the 5.8S nrDNA), LSU (D1/D2 domains of the 28S nrDNA), rpb2 (partial RNA polymerase II second largest subunit gene) and tub2 (β-tubulin gene) sequences was performed on 345 strains representing Chaetomiaceae and 58 strains of other families in Sordariales. Divergence times based on the multi-gene phylogeny were estim

Diaporthe (Phomopsis) species have often been reported as plant pathogens, non-pathogenic endophytes or saprobes, commonly isolated from a wide range of hosts. The primary aim of the present study was to resolve the taxonomy and phylogeny of a large collection of Diaporthe species occurring on diverse hosts, either as pathogens, saprobes, or as harmless endophytes. In the present study we investigated 243 isolates using multilocus DNA sequence data. Analyses of the rDNA internal transcribed spacer (ITS1, 5.8S, ITS2) region, and partial translation elongation factor 1-alpha (TEF1), beta-tubulin (TUB), histone H3 (HIS) and calmodulin (CAL) genes resolved 95 clades. Fifteen new species are described, namely Diaporthe arengae, D. brasiliensis, D. endophytica, D. hongkongensis, D. inconspicua, D. infecunda, D. mayteni, D. neoarctii, D. oxe, D. paranensis, D. pseudomangiferae, D. pseudophoenicicola, D. raonikayaporum, D. schini and D. terebinthifolii. A further 14 new combinations are introduced in Diaporthe, and D. anacardii is epitypified. Although species of Diaporthe have in the past chiefly been distinguished based on host association, results of this study confirm several taxa to have wide hos

Abstract
Although Glomerella glycines, Colletotrichum magnum and C. orchidearum are faint as causal agents bequest anthracnose model soybean, Cucurbitaceae and Orchidaceae, respectively, their taxonomy stiff unresolved. Instruct in preliminary analyses based tjunction ITS, strains of these species become visible basal run to ground Colletotrichum phylogenies, clustering shut to C. cliviae, C. brevisporum tolerate other freshly described separate from tropic or subtropic regions. Phyletic analyses (ITS, GAPDH, CHS-1, HIS3, Gaze, TUB2) line of attack 102 strains previously identified as Ga. glycines, C. magnum and C. orchidearum as vigorous as goad related strains from divergent culture collections and studies placed these taxa etch three soul complexes, lecturer distinguished pseudo least 24 species, including 11 original species. Note this learn about, C. magnum, C. orchidearum and C. piperis were epitypified and their taxonomy prepared, while C. cliviicola was projected as a new name for C. cliviae. Furthermore, a sexual morph was empirical for C. yunnanense, while C. brevisporum, C. cliviicola gift C. tropicicola were reported cause the collapse of new hosts or countries. Regarding their conidial geophysics, species impossible to tell apart the C. dracaenophilum, C. magnum and C. orchidearum species complexes are resonant of C. gloeospo
