Halosarpheia unicellularis sp. nov. (Halosphaeriales, Ascomycota) based on morphological and molecular evidence

Halosarpheia unicellularis sp. nov. is described from decayed attached wood ofAvicennia marina collected from two mangrove sites in the Red Sea, Egypt. The ascomycete is compared with other marine taxa having ascospores with polar unfurling appendages. It is also compared with other marine genera with oval, round or ellipsoid hyaline, unicellular ascospores, but for which appendages have not been reported. Molecular data confirms the assignment of the fungus toHalosarpheia which forms a clade with the type speciesHalosarpheia fibrosa.

Morphological and molecular evidence for a new species of Perenniporia (Basidiomycota) from Tibet, southwestern China

A new polypore, Perenniporia tibetica, collected in Xizang (Tibet), southwestern China, is described and illustrated on the basis of morphological and molecular characters. Perenniporia tibetica is characterized by an annual growth habit, resupinate basidiocarps with a creambuff to pinkish-buff pore surface and white to cream-colored rhizomorphs, a dimitic hyphal system with slightly dextrinoid and distinctly cyanophilous skeletal hyphae, and basidiospores that are ellipsoid, truncate or not, strongly dextrinoid, and cyanophilous, 6.7–8.7 × 5.3–6.8 μm. Its preliminary phylogenetic relationships are inferred based on sequence data from the ribosomal ITS and LSU regions, both suggesting that P. tibetica forms a distinct lineage in the genus Perenniporia.

Multigene phylogeny of Synura (Synurophyceae) and descriptions of four new species based on morphological and DNA evidence

We used phylogenetic analyses based on multiple gene sequences (partial nr SSU and LSU rDNA, partial pt LSU rDNA, psaA and rbcL) from 148 strains (including three outgroups) and scale ultrastructure to examine phylogenetic relationships among species of the colonial genera Synura and Tessellaria. The phylogenetic tree based on the combined dataset was congruent with ultrastructural characteristics of the scales. Synura was divided into three major clades, two including species in section Synura, and one representing section Peterseniae. One clade, consisting of seven strains of S. uvella (section Synura), diverged at the base of the genus. The second clade consisted of the remaining species belonging to the section Synura. The third clade, containing organisms in the section Peterseniae and characterized by scales possessing a keel, was monophyletic with strong support values. Based on our findings, S. uvella needs to be in a separate section from other spine-bearing species, and we therefore propose new sectional ranks; Synura, Peterseniae, Curtispinae (presence of body scales with slender spines, tubular scales and caudal scales). We further propose four new species based on phylogenetic analyses and unique scale characters: S. longitubularis sp. nov., S. sungminbooi sp. nov., S. soroconopea sp. nov. and S. lanceolata sp. nov. Lastly, we propose a new genus name, Neotessella, to replace the invalid use of the name Tessellaria.

Abstract

A new Inner Mongolian endemic species, Bryoerythrophyllum neimonggolicum X.-L.Bai & C.Feng is described and illustrated from China. It is characterized by lingulate to broad-lanceolate leaves with obtuse or rounded apex, leaf margins broadly recurved to revolute to near the apex, bulging laminal cells, basal cells with thickened walls and the absence of lax and enlarged basal cells. This species is compared with closely related species and its ecology is discussed.     

Two new Fomitopsis species from southern China based on morphological and molecular characters

Fomitopsis cana sp. nov. and F. subtropica sp. nov. are described from southern China based on morphological and molecular characters. Both species have annual, effused-reflexed basidiomata with several small imbricate pilei protruding from a large resupinate part. F. cana is characterized by its mouse-grey to dark grey basidiomata, pores 5–8 per mm, and small cylindrical to oblong-ellipsoid basidiospores (5–6.2?×?2.1–3 μm). F. subtropica is characterized by its white, cream, straw-yellow to more or less flesh-pink basidiomata which was easily separable from the substrate, smaller pores (6–9 per mm) and smaller basidiospores (3.2–4?×?1.8–2.1 μm), and presence of yellowish oil-like substances in trama. Phylogenetic analysis based on combined ITS and nLSU sequences suggest that the two new species belong in the Fomitopsis sensu stricto group within the Antrodia clade.

Light microscope photographs of the significant characters are provided and its distinctions from closely related taxa are discussed. A key to Chinese Didymodon species with smooth laminal cell is provided.     

Evolutionary history of two allopatric Terricola species (Arvicolinae, Rodentia) from molecular, morphological, and palaeontological data

To investigate the phylogenetic and phylogeographical relationships of arvicolines, we use several Western European ground voles. More particularly, our study is focused on Microtus ( Terricola ) savii and M. ( T. ) pyrenaicus . These two allopatric species are usually considered as having originated from the same ancestor, possibly M . ( T. ) mariaclaudiae . We propose molecular and morphological approaches: nucleotidic data from the mitochondrial cytochrome b and 12S rRNA genes and global morphological analyses from the first lower molar. Four other Terricola species ( multiplex , lusitanicus , duodecimcostatus , subterraneus ) were added to the data set for both analyses, and two other vole species ( Clethrionomys glareolus and Chionomys nivalis ) as outgroup to the molecular analysis, and five fossil populations to the morphological one. Palaeontological data are also widely taken into account. Both molecular and morphological analyses indicate that intra- Terricola relationships reflect the present-day geographical distribution of our data set species. Our results show that M. ( T. ) savii and M. ( T. ) pyrenaicus are from separate speciation events leading to two different biogeographical groups, respectively the Alpine–Italian group and the French–Iberian group, the latter being much more homogeneous. These speciation events could be related to Quaternary climatic changes, which induced southward migration, leading first to M. ( T. ) savii and second to M. ( T. ) pyrenaicus . The classical hypothesis of a geographical speciation for these two taxa from M. ( T. ) mariaclaudiae is invalid. However, the morphological data suggest a potential phylogenetic relationship between M. ( T. ) mariaclaudiae (ancestor) and M. ( T. ) pyrenaicus (descendant).  © 2008 The Linnean Society of London, Biological Journal of the Linnean Society , 2008, 93 , 309–323.     

Crinipellis brasiliensis, a new species based on morphological and molecular data

Crinipellis perniciosa infects a diversity of hosts causing severe damage to T. cacao production in many Brazilian growing regions. We compared isolates of Crinipellis from different geographic origins and hosts in Brazil by structural analysis using light (LM) and scanning electronic microscopy (SEM), as well as RFLP and sequence data based on the nuclear rDNA ITS region. Statistical analyses of morphometric data of basidia and basidiospores revealed a distinct group of isolates of Crinipellis obtained from Heteropterys acutifolia when compared to representatives from Theobroma cacao, Solanum lycocarpum and Heteropterys nervosa. A similar distinction also was observed based on sequence data of the ITS region such that combined results allowed for the segregation of a new species within the genus Crinipellis.

Revision of Australian Matini diving beetles based on morphological and molecular data (Coleoptera,Dytiscidae, Matinae), with description of a new species

Morphological characters and mitochondrial DNA sequence data were used to revise the Australian diving beetles in the genera Allomatus Mouchamps, 1964 and Batrachomatus Clark, 1863. As a result of these studies Allomatussyn. n. is synonymised with Batrachomatus, and Allomatus nannup Watts, 1978 from SW Australia and Allomatus wilsoni Mouchamps, 1964 from SE Victoria are transferred to Batrachomatus. The four Australian Matini species knownso far are re-described, and Batrachomatus larsonisp. n. from the Windsor Tableland in NE Queensland is described. After more than 40 years Batrachomatus wilsoni has been re-discovered in two rivers in Victoria. We delineate the species using traditionally employed morphological structures such as in the male genitalia and body size, shape and colour pattern, as well as mitochondrial cox1 sequence data for 20 individuals. Important species characters (median lobes, parameres and colour patterns) were illustrated. We provide an identification key and outline distribution and habitat preferences of each species. All Australian Matini are lotic, inhabiting permanent and intermittent streams, creeks and rivers.
