A catalogue and bibliography of Batrachospermales (Rhodophyta) in China is presented. There are 33 species belonged to 10 genera and 2 families. Species distribution among the 10 gen- era are as follows: Batrachospermum, 6; Kumanoa, 10; Montagnia, 1; Nothocladus, 1; Sheathia, 3; Sirodotia, 4; Torularia, 1; Virescentia, 1; Lemanea, 4; and Paralemanea, 2. According to geo- graphical distribution, the members of Batrachospermales in China are composed of 3 types: cos- mopolitan (distributed on at least 5 continents or 10 countries of the world), 6 taxa; regionally dis- tributed (distributed in no more than 4 continents or 10 countries), 15 taxa; and endemic to China (collected, described and reported only from China), 12 taxa. Most species were distributed in East and Southwest China, up to or more than 20 species. Eight species were recorded in North and Central China, respectively. Only 1 or 2 species were found in Northeast and South China, respec- tively. However, no one has been found in the northwest China so far. Thirteen species of Batra- chospermales in China have been confirmed by morphological characteristics combining with mo- lecular data. But unfortunately, the other species are unable to obtain molecular data because fresh collections are not available, which need to be confirmed or rejected in future studies. Kylin, H.

In this paper, a new spider species of the genus Loxosceles is described on the basis of morphological and molecular data. The phylogenetic relationship of the new species is discussed through the lens of molecular data (cox1, rrnL and H3 genes). Specimens were collected from three Iranian caves in the provinces of Fars, Yazd and Khuzestan, and the specimens showed morphological characteristics that allowed us to easily distinguish Loxosceles persica n. sp. from L. mrazig, which is its sister species, and from the cosmopolitan L. rufescens, which is a widely distributed species throughout the Mediterranean basin and the Middle East. It is the first Loxosceles species endemic to the Middle East.

A New Species

A new polypore, Rhodonia tianshanensis, collected from West Tianshan Nature Reserve in Xinjiang Autonomous Region (northwest China), is described and illustrated based on morphological characteristics and molecular evidence. It is characterized by having resupinate basidiomata with an oblique tube layer, fusoid cystidioles in the hymenium, and cylindrical basidiospores. Based on multiple loci DNA sequences including the internal transcribed spacer (ITS), the large subunit (nLSU), and the second subunit of RNA polymerase II (RPB2) regions, our phylogeny strongly supported R. tianshanensis as a new species belonging to the genus Rhodonia.

A new mycoparasitic fungal species, Tuberculina photiniae sp. nov., is proposed based on morphological and molecular evidence. The species is characterized by its depressed hemispherical pale lilac to greyish purple sporodochia breaking through leaf surfaces, septated conidiophores with vinaceous lower parts and colourless upper parts, and the presence of colourless globose, subglobose or scarcely wide-ellipsoid conidia. Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analysis based on molecular data of ITS sequences showed that Tuberculina photiniae belongs to the Tuberculina-Helicobasidium clade and is closely related to H. longisporum and H. mompa. Further investigation was carried out for representative taxa in the Tuberculina-Helicobasidium group based on ITS+nLSU sequences in which the results demonstrated that the new species formed a monophyletic lineage and grouped with H. longisporum and H. mompa. Both morphological and molecular evidence confirmed the placement of the new species in the Tuberculina-Helicobasidium clade.

<p>Red algal parasites are common within red algae and most parasites are closely related to their host. Red algal parasites can switch hosts and their development is unique. Red algal parasites are poorly known in New Zealand. There are only four parasites described in New Zealand and those are based on morphological characteristics. This thesis focuses on the two red algal parasites Rhodophyllis parasitica sp. nov. and Pterocladiophila hemisphaerica from New Zealand. First, development and phylogeny and distribution of an undescribed red algal parasite growing on Rhodophyllis membranacea was investigated. Microscopy, molecular markers (ITS2, cox1, cox2-3 spacer) and phylogenetic analysis, and herbarium sampling were used to address these questions. The parasite, described as Rhodophyllis parasitica sp. nov. shows a close relationship of all genomes to Rhodophyllis membranacea, which suggests that the parasite evolved from its hosts. The parasite is widely distributed throughout New Zealand. The second parasite, Pterocladiophila hemisphaerica was grouped taxonomically, based on morphology, in the order Gracilariales and parasitizes Pterocladia lucida in the order Gelidiales. Molecular marker were used to reveal the relationship of Pterocladiophila hemisphaerica to its host: if the parasite is grouped in the Gracilariales or the Gelidiales; if host switches might have occurred; and if atp8 is present in the parasite. Nuclear DNA (SSU rRNA, LSU rRNA), mitochondrial (cox1) and plastid regions (rbcL-rbcS spacer) from the parasite were sequenced and phylogenetic analysis performed. New primer were designed to amplify atp8 and genetic analysis performed. Pterocladiophila hemisphaerica evolved in the Florideophytes but neither in the Gracilariales or Gelidiales and the parasite possibly switched hosts at least two times, which was shown by three different origins of chloroplast, mitochondria and nuclear DNA. Atp8 in the parasite is present but probably a pseudogene. Rhodophyllis parasitica sp. nov. is the first described red algal parasite species in New Zealand in 55 years and Pterocladiophila hemisphaerica is the first parasite with organelles and nuclei with different histories of origin.</p>

Three New Species

Three new species of Tricholomopsis were described and illustrated based on collections from Shanxi Province in North China. Tricholomopsis galeata sp. nov. is closely related to T. pteridiicola but distinguished from the latter by its large pileus with red to purple reddish fibrous scales and the absence of pleurocystidia. Tricholomopsis pallidolutea sp. nov. is similar to T. sulfureoides and T. flavescens in macromorphology but is differentiated from T. sulfureoides by its dark orange fibrous scales on the pileal surface and narrow basidiospores (avQ = 1.77 ± 0.33), and from T. flavescens by its abundant pleurocystidia. Tricholomopsis mitirubicunda sp. nov. is morphologically similar to T. rutilans but is distinguished from the latter by its abundant pleurocystidia. Phylogenetic analysis supported the taxonomic position of the three new species in the genus Tricholomopsis.

Two new species of Dentipellis are described from China based on morphological characteristics and molecular data. Dentipellis longiuscula is characterized by annual, resupinate hydnoid basidiomata with moderately long spines, rough basidiospores (5–6 × 3–3.6 µm) and absence of gloeoplerous hyphae and gloeocystidia. Dentipellis tropicalis is characterized by hydnoid basidiomata with numerous gloeocystidia presenting in hymenium, and minutely rough basidiospores (5–5.5 × 2.5–3.2 µm). Phylogenetic analysis based on the internal transcribed spacer (ITS) and nuclear large subunit ribosomal (nLSU) RNA gene regions confirmed the affinity of the new species in Dentipellis and indicated their relationships with other species in the genus.

A new freshwater species of Chrysophyceae, Dinobryon taiyuanensis, is described from Linde Lake in Shanxi province, China. This new species is similar to D. sertularia, the type species of the genus, in the shape of the lorica and organization of the colony. The cells have two heterokont flagella surrounded by a lorica and occurred both as free-living, solitary cells or in branched colonies. The lorica of our new species like a bent or S-shaped cone, and shorter than the lorica in D. sertularia. In addition to describing the morphological features of D. taiyuanensis, a phylogenetic analysis based on sequences of the nuclear small subunit ribosomal DNA (SSU rDNA) and internal transcribed spacer (including internal transcribed spacer 1, 5.8S rDNA and internal transcribed spacer 2) placed this alga in single clade with a considerable sequence distance from the other Dinobryon species. Thus, results of both morphological comparisons and phylogenetic analysis based on molecular data suggest this alga as a new species, increasing the total number of recognized freshwater Chrysophyta species in China.

Batrachospermum is a widely distributed genus in China. Nonetheless, many taxa recorded previously have no molecular data. In this study, a new species of Batrachospermum called Batrachospermum qujingense is described and illustrated from Qujing, Yunnan, Southwest China, based on morphological observations and a phylogenetic analysis. This species is distinguished morphologically from other species by dioecious thalli, straight carpogonial branches with 7–9 cells and stalked angled obovoid or inflated-clavate trichogynes. In addition, a phylogenetic analysis of the molecular data from the rbcL, COI-5P, and psbA genes indicated separation between the new species proposed in this study and other species in the genus Batrachospermum (4.0–5.3% for rbcL, 7.7%–10.6% for COI-5P, and 2.2–3.2% for psbA ). This is the first species of Batrachospermum reported in Yunnan and the third species of Batrachospermum with molecular data in China. The description of the new species and geographical distribution expands the diversity of freshwater red algae in China.

Abstract Background:Liaoning virus(LNV) is a member of the genus Seadornavirus, family Reoviridae and has been isolated from kinds of sucking insects in Asia and Australia. However, there are no systematic studies describe the molecular genetic evolution and migration of LNVs isolated from different time, regions and vectors.Methods:Here, a phylogenetic analysis using Bayesian Markov chain Monte Carlo simulations was conducted on the LNVs isolated from a variety of vectors during 1990-2014,worldwide. Results:The phylogenetic analysis demonstrated that the LNV could be divided into 3 genotypes, of which genotype 1 mainly composed of LNVs isolated from Australia during 1990 to 2014 as well as the original LNV strain(LNV-NE97-31) isolated from Liaoning province in northern China in 1997,genotype 2 comprised of the isolates all from Xinjiang province in western China and genotype 3 consisted the isolates from Qinghai and Shanxi province of central China. LNVs emerged about 272 years ago in Australia and gradually evolved into three LNV lineages in the order genotype1(at 73.0 years ago),genotype2(at 46.5 years ago)and genotype 3(at 25.3 years ago). Following further phylogeographic analysis, we proposed that Australia (113°E-153°E,10°S-42°S) was the source of LNVs and the genotype 1 LNVs transmitted from this region to Liaoning province(118°E-125°E,38°N-43°N) in Northeast Asian continent then further spread across the central part of China to Xinjiang province in western China(75°E-95°E,35°N-50°N).Conclusion: LNVs were initially isolated from Liaoning province of China in the Northeast Asia, however, the present study demonstrated that LNVs were originated from Australia in the South Pacific region and transmitted to mainland China then rapidly spread across China and evolved three different genotypes.The above results suggested that LNV had the characteristics of long-distance transmission and there were great genetic diversity existed in the LNV population. Therefore, it is of great importance to strengthen the monitoring of the population variation of LNV and maintain vigilance to avoid LNV breaking through the species barrier and further clarify its relationship to human and animal infection.

Sponges, the most ancient multicellular metazoan, were widely distributed across habitats. Vietnam is known to possess a high biodiversity of sponges, however, they are mostly identified based on morphological characteristics and lack the molecular data. In the current study, the phylogenetic relationship of some sponges (Demospongiae) in Vietnam was constructed using two independent markers (COI and 18S rRNA). In this paper the individual markers (COI and 18S rRNA) were successfully used to identify some sponge taxa at the species level. The obtained results showed the congruence of molecular taxonomy using two independent markers. However, our study showed that a combination of the two markers provided more information and supported better for sponge identification. At order level, the COI tree and 18S rRNA tree also recovered the same clades, indicating the congruence of COI and 18S rRNA genes in sponge classification. However, branching order of the clades in COI tree was weakly supported and slightly different from those in 18S rRNA tree.
