Molecular phylogeny of Neodevriesia, with two new species and several new combinations

ABSTRACT

To identify Cladosporium-like isolates associated with marine algae, phylogenetic analyses were conducted using a combined data set of the nuc rDNA internal transcribed spacer (ITS) region (ITS1-5.8S-ITS2 = ITS), 28S gene, and partial RNA polymerase II second largest subunit (RPB2). These isolates were confirmed as belonging to Neodevriesia (Neodevriesiaceae), a genus recently segregated from Cladosporium. Two new species, Neodevriesia cladophorae and N. grateloupiae, are described on the basis of morphological and phylogenetic distinctions, and this is the first report of Neodevriesia species from the marine environment. Devriesia fici, D. fraserae, and D. sardiniae are transferred to Neodevriesia based on the phylogenetic affinities and morphological characters of their ex-type specimens.
