Background and aims – Species delimitation is a necessary investigation for widely distributed species. Examination of herbarium specimens descriptions in local floras revealed that two forms Silene villosa were recognized. Form B S. has been identified as separate species named wendelboi . However, the latter was not treated floras. By using molecular tools, we investigated if these should be ...

SNPs from nrDNA and cp trnC-trnD were analyzed from J. indica, J. recurva and Rushforth's juniper from Bhutan and compared with previous terpene and RAPD data. These data, taken together, show that Rushforth's juniper is allied, but distinct from J. indica and a new variety is named: J. indica var. rushforthiana R. P. Adams from Bhutan.

The karyotype is shaped by different chromosome rearrangements during species evolution. However, determining which rearrangements are responsible for karyotype changes is a challenging task and the combination of a robust phylogeny with refined karyotype characterization, GS measurements and bioinformatic modelling is necessary. Here, this approach was applied in Heterotaxis to determine what ...

Scopulariopsis-like species are often reported from the indoor environment, as well as from clinical samples. The lack of type isolates and thorough phylogenetic studies in the Microascaceae hampered the correct identification of these isolates. Based on recent phylogenetic studies, which resulted in multiple name changes, the aim is to molecularly identify the Scopulariopsis and scopulariopsis...

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 recognise 12 families and five unknown lin...

Abstract Section Anomali is a species-rich group in North America belonging to Cortinarius , the most diverse genus Agaricales. This study based on extensive morphological investigations and molecular methods using 191 nrDNA ITS sequence data recovered 43 phylogenetic species from which 14 are described here as new science. We sequenced ten type materials belonged eight species. The synonymy of...

To determine the evolutionary relationships among all members of the genus Atractylodes (Compositae, Cardueae), we conducted molecular phylogenetic analyses of one nuclear DNA (nrDNA) region (internal transcribed spacer, ITS) and one chloroplast DNA (cpDNA) region (intergenic spacer region of trnL-F). In ITS and ITS + trnL-F trees, all members of Atractylodes form a monophyletic clade. Atractyl...

Fungal taxonomists routinely encounter problems when dealing with asexual fungal species due to poly- and paraphyletic generic phylogenies, and unclear species boundaries. These problems are aptly illustrated in the genus Phoma. This phytopathologically significant fungal genus is currently subdivided into nine sections which are mainly based on a single or just a few morphological characters. ...
