Abstract

A new species of Preussia as an endophyte of different typical Mediterranean plant species is newly described and illustrated based on molecular and morphological features. Preussia mediterranea resembles P. australis, P. africana and P. similis from a morphological point of view, but appeared closer to P. minima and P. isabellae by molecular analysis. Phylogenetic analysis of the entire ITS region combined with the D1-D2 domains of the 28S rRNA gene, and a fragment of the elongation factor EF-1 alpha gene, using Maximum Likelihood and a Bayesian Markov Chain Monte Carlo approach, generally resulted in statistically well-supported clades for all the species studied. Morphological data and molecular phylogenetic analysis supported the recognition of the new taxon.
