Taxonomy, DNA barcoding and phylogeny of three new species of Pythium from Canada
Three new species of Pythium, namely, P. oopapillum, P. emineosum and P. camurandrum are presented in this paper based on morphological descriptions and molecular phylogenetic characterisation. These new species were isolated from various ecological regions in Canada. They have unique morphological features in the genus Pythium, and form distinct clades in maximum parsimony analyses, which are also supported by maximum likelihood phylogeny using general time reversible model (GTR), and Bayesian inference (BI) phylogeny using Markov Chain Monte Carlo (MCMC) analysis methods. A comparative study of the new species with closely related taxa, their clade positions, and morphological features are described in this paper.

More about this publication?
- Persoonia aims to publish papers dealing with molecular phylogeny and evolution of fungi. A further aim is to promote fungal taxonomy by employing a polythetic approach to clarify the true phylogeny and relationships within the kingdom Fungi. The journal publishes high-quality papers elucidating known and novel fungal taxa at the DNA level, and also strives to present novel insights into evolutionary processes and relationships. Papers to be considered include research articles and reviews.
Papers are published using a Fast Track system. This implies that the papers are immediately published online and freely available through the internet via this website. Volumes appear twice a year (June and December). From Volume 36 onwards (2016) hard copy volumes will only be made available through printing-on-demand. The issues can be ordered separately through the Publication Division of Naturalis Biodiversity Center; e-mail: [email protected]
Persoonia is a journal published jointly by the Naturalis Biodiversity Center and the Westerdijk Fungal Biodiversity Institute.
