A New Species

The morphological characterization and phylogenetic analysis based on molecular methods were executed on the freshwater Hildenbrandia specimens collected in this study. The cell size and filament height of the specimen collected from Pipa Lake, Japan were larger than the widely recognized species Hildenbrandia angolensis and Hildenbrandia rivularis, whereas overlapped with Hildenbrandia jigongshanensis. Based on molecular evidences of rbcL phylogenetic analysis and comparison of ITS1 secondary structure, specimen collected from Shiga Prefecture, Japan was proposed as a new species Hildenbrandia japananense. It brings the freshwater Hildenbrandia species in Japan to two. The specimens collected from Niangziguan, Shanxi province, China represent two new records of H. jigongshanensis. It enriches the species diversity of genus Hildenbrandia and increases the distribution diversity of this freshwater red algal taxon.

A New Species

A new species of freshwater red alga, Sheathia matouensis, is described and illustrated based on material collected in spring water from the Hongdong region of Shanxi province, China. Phylogenetic analysis of sequence data from the rbcL and psbA indicated the separation between S. matouensis and the other species of genus Sheathia. Additionally, from a morphological point of view, S. matouensis differs from other species of the genus Sheathia by the smaller whorls and carpogonium. Therefore, the results based on both morphological observation and molecular evidences facilitated the proposal of this new species - S. matouensis. It represents another species in the freshwater red algal diversity in China and the description of this new species provides more molecular data for phylogenetic analysis of genus Sheathia.

Gloiosaccion Harvey, with type G. brownii (Rhodymeniaceae, Rhodymeniales), is a red algal genus characterized by the presence of large, hollow and saccate vesicle-shaped thalli arising from small solid axes. Whereas Gloiosaccion has traditionally been viewed as being closely related to Botryocladia (Agardh) Kylin, a multi-marker phylogenetic analysis based on chloroplast-encoded rbcL and UPA and nuclear LSU rDNA sequences instead places Gloiosaccion brownii and G. pumila in the Chrysymenia clade that includes the generitype C. ventricosa (Lamouroux) J. Agardh. Gloiosaccion is reduced to synonymy with Chrysymenia J. Agardh, a taxonomic move first advocated by De Toni in 1900. In addition to C. brownii (Harvey) De Toni, “Gloiosaccion” brownii var. firmum Harvey and “G.” pumilum J. Agardh are recognized as the distinct species Chrysymenia coriacea comb. et stat. nov. and C. pumila (J. Agardh) Weber-van Bosse, respectively. A new species, C. pseudoventricosa sp. nov. is proposed to accommodate specimens going under the name C. ventricosa (J.V. Lamouroux) J. Agardh from the Gulf of Mexico and Caribbean Sea.

Stropharia populicola sp. nov., found during autumn under Populus spp. in Shanxi Province of North China, is described and illustrated. Stropharia populicola is similar and closely related to S. jilinensis and S. scabella but can be distinguished from the latter two species by the acanthocytes commonly present in the hymenium. Phylogenetic analysis supports its taxonomic position in the genus Stropharia.

The genus Colaconema, containing endophytic algae associated with economically important macroalgae, is common around the world, but has rarely been reported in Taiwan. A new species, C. formosanum, was found attached to an economically important local macroalga, Sarcodia suae, in southern Taiwan. The new species was confirmed based on morphological observations and molecular analysis. Both the large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (rbcL) and cytochrome c oxidase subunit I (COI-5P) genes showed high genetic variation between our sample and related species. Anatomical observations indicated that the new species presents asexual reproduction by monospores, cylindrical cells, irregularly branched filaments, a single pyrenoid, and single parietal plastids. Our research supports the taxonomic placement of C. formosanum within the genus Colaconema. This study presents the third record of the Colaconema genus in Taiwan.

Amanitatullossiana, a new species of Amanita [subgenus Lepidella] section Lepidella from India is described. The species is characterised by its ash grey to brownish-grey pileus covered with dark grey to greyish-black universal veil remnants, the upper part of its rooting stipe base covered by several rows of recurved scales, broadly ellipsoid to ellipsoid basidiospores, absence of basidial clamp connections and pileal remnants of universal veil comprising abundant, disordered inflated cells intermixed with scattered filamentous hyphae. Molecular phylogenetic analysis and morphology both support the association of A.tullossiana with species of Bas’ stirps Cinereoconia – A.cinereoconia and A.griseoverrucosa. Two species, A.griseoverrucosa and A.virgineoides are reported here as new records for India.

During a survey to characterize the diversity of sooty blotch and flyspeck fungi in China, we obtained an isolate from a fungal colony exhibiting sooty blotch and flyspeck signs on the petiole of brown bollygum (Litsea glutinosa) in Guangxi, China. Based on phylogenetic analysis and morphological characterization, a new species, Zasmidium litseae is introduced. The new species is characterized by its swollen, straight or geniculate conidiogenous cells.

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.

A new species, Phylloporia lespedezae, is described from Shanxi Province on the basis of morphological, ecological characters and molecular evidence. It is characterized by having an annual, pileate basidiocarps with wavy edge, duplex context separated by a black line, a monomitic hyphal system with simple septate generative hyphae, the presence of fusoid cystidioles, yellowish, broadly ellipsoid, thick-walled basidiospores, and growing on Lespedeza (Fabaceae) only. Phylogenetic analysis based on nuclear large subunit ribosomal DNA (nLSU) strongly support P. lespedezae as a distinct species within the genus of Phylloporia. Detailed description with illustration is provided for the new species and its relationships with similar species are discussed. In addition, a key to all 41 species of Phylloporia is provided.

AbstractSporastatia crassulata Yakovchenko & Davydov sp. nov. is described and a phylogenetic analysis (mtSSU) is presented, confirming its distinctness and indicating a sister relationship with S. testudinea. The species is unique among Sporastatia species in having a distinctly squamulose, thick, uneven thallus composed of convex, rounded squamules irregularly ascending in the central part of the thallus. The new combination Sporastatia karakorina (Poelt & Obermayer) Davydov & Yakovchenko is proposed. The type specimen of S. subasiatica was examined. A key to the six species of Sporastatia is given. Mountainous Central Asia appears to be the centre of species diversity and endemism for Sporastatia.

The octocoral faunas occurring at mesophotic depths (from 40 to 150 m) have been relatively unexplored. Recent expeditions to Hannibal Bank, a guyot seamount off Pacific Panama, have yielded new octocoral species and new records for the tropical eastern Pacific. Herein, we describe a new species for the genus Psammogorgia Verrill, 1868a, Psammogorgia pax sp. nov., characterized by having a whitish flabellate colony with orange polyp apertures, slightly raised and sparse calyces, and colorless coenenchymal sclerites (which are mostly spindles and large wart-clubs). A preliminary molecular phylogenetic analysis supports the differences between the new species with other congener and related taxa.
