During an investigation of lignicolous ascomycetes from Luxembourg, we isolated a Phialophora -like species that produced striking red colonies. To confirm the identity of this fungus as Catenulifera rhodogena , we compared it with isolates of Catenulifera rhodogena and Hyphodiscus hymeniophilus on a variety of media. Portions of the β-tubulin gene and the nuclear ribosomal DNA cistron (internal transcribed spacers (ITS) and large subunit (LSU)) were sequenced to examine the relationship of isolates of Catenulifera rhodogena and Hyphodiscus hymeniophilus from different substrates and to test the hypothesis that Cadophora and Catenulifera are congeneric. The phylogenetic position of Catenulifera within the Ascomycota was investigated based on the analysis of the small-subunit (SSU) rDNA sequences. The isolates examined were indistinguishable micromorphologically and closely related phylogenetically. Three strains of Catenulifera rhodogena from bark or wood and one strain from Piptoporus betulinus formed a strongly supported clade in analyses of β-tubulin and ITS sequences. This clade did not encompass the ex-type isolates of Cistella rubescens and Scopulariopsis rhodogena or a second isolate of Catenulifera rhodogena from Piptoporus betulinus. Analysis of partial LSU sequences confirmed the close phylogenetic relationship of Catenulifera rhodogena and Hyphodiscus hymeniophilus but provided no evidence that the isolates could be grouped by substrate or that Catenulifera is synonymous with Cadophora. The position of Catenulifera within the Helotiales was not resolved based on the comparison of LSU and SSU sequences, but the isolate for which we obtained complete SSU sequence grouped with the root endophyte Phialocephala fortinii. Comparison of ITS sequences confirmed the close phylogenetic relationship of Hyphodiscus to members of the Dermateaceae and Hyaloscyphaceae.

The phylogenetic relationship of eight Iris species (I.flavisimma, I.ventricosa, I.bungei,I.kaempferi, I.tenuifolia, I.lactea, I.tigrida, I.dichotoma) were studied by PCR using six specificprimers (S-523, Z1204R, trnL, trnF and ITS1, ITS4). All species except I.ventricosa wereidentified when using S-523, Z1204R and trnL, trnF primers and the DNA fragment size rangedbetween 500 to 600 bp and 800 bp, respectively. Primers ITS1 and ITS4 produced double bandsin about 500 and 1500 bp to I.bungei, I.kaempferi, and I.lactea species. On the phylogenetic tree, some iris species have close relations based on chloroplastic DNA sequences. The closest relationships showed between I.sanguinea and I.sibirica, I.rutenica and I.uniflora. Also I.tenuifolia, I.ventricosa and I.halophila located on one branch of phylogenetic tree.

A New Species

Peliosanthes crassicoronata is described and illustrated as a new species from southern Vietnam. It somewhat resembles P. macrostegia in having drooping bowl-shaped purplish flowers, but is readily distinguishable by the larger leaves with more numerous longitudinal veins, internally thickly ribbed staminal corona, and pistil with a hexagonal ovary and an indistinct style. The phylogenetic relationship of the new species was inferred from an analysis of chloroplast and nuclear DNA sequences.

Although the phylogenetic relationship of Western Palearctic brown frogs has been repeatedly studied, the taxonomic status and phylogenetic relationship of Anatolian-Hyrcanian brown frogs is still not fully resolved. Here, we assess the phylogenetic status of these species among Western Palearctic brown frogs with special emphasize on Iranian populations based on two partial mitochondrial DNA sequences (16S rRNA and cytochrome b genes) and the application of a molecular clock. Our results clearly show that Western Palearctic brown frogs underwent a basal radiation in to two main monophyletic clades, the European brown frogs plus the Asian R. asiatica and the Anatolian-Hyrcanian brown frogs, during Early Miocene ca. 20.2 mya. The Hyrcanian (R. pseudodalmatina) and the Anatolian lineage diverged approximately 16.6 mya. The further diverged into two subclades, R. tavasensis and R. macrocnemis, during the Middle Miocene, 14.5 mya. Our results suggest that diversification within these lineages may be closely linked to the formation of Neotethys and Paratethys and the subsequent uplift of the Turkish-Iranian plateau during the Early Miocene which led to restricted gene flow among brown frogs in these regions. Contrary to previous studies, we conclude that the Plio-Pleistocene epoch seems to be not associated to further significant speciation events within Anatolian-Hyrcanian brown frogs.
