A new species of Neoroussoella (Roussoellaceae) collected in Taiwan is introduced from Pennisetum purpureum with both asexual and sexual morphs. Phylogenetic analysis of a concatenated LSU-ITS-SSU-TEF1-α-RPB2 sequence dataset reveals that the new species forms a distinct sister clade with N. bambusae with high statistical support (100% ML/ 1.00 BYPP). Neoroussoella alishanense is morphologically similar with the generic type, N. bambusae, but N. alishanense is distinct in having larger ascomata and its ascospores lack a mucilaginous sheath. While, N. bambusae has smaller ascomata and its ascospores are surrounded by a mucilaginous sheath. A comparison of ITS, RPB2 and TEF1-α nucleotide bases shows that they are distinct species.

Acrophialophora liboensis, a new fungus from soil samples in Libo County, Guizhou Province, China, is illustrated and described on the basis of morphological and molecular sequences data. Phylogenetic analysis based on internal transcribed spacer (ITS) and β-tubulin sequences demonstrated that A. liboensis is a distinct species closely related to A. cinerea and A. furcata. Morphologically, A. liboensis is characterized by solitary and lateral phialides tapering into thin necks and long chains of ellipsoidal or oval conidia. The ex-type living culture has been deposited in CGMCC, Beijing City, China.

A New Species

Adenophora xiaoxiensis (Campanulaceae), a new species from central China is described and illustrated. Molecular phylogenetic analysis (based on nuclear ribosomal ITS and the plastid regions trnL-F and matK) and morphology support recognition of A. xiaoxiensis as a distinct species sister to A. wilsonii. Adenophora xiaoxiensis has ovate-elliptic to broadly lanceolate cauline leaves with irregularly biserrate margins, triangular-ovate calyx lobes with 1-3 pairs subulate or linear teeth and a white corolla. About 70 individuals were observed in a restricted area of less than 100 m2. The habitat could be easily disturbed or destroyed, thus, we assessed it as endangered (EN), based on Criteria D of the International Union for Conservation of Nature Red List Categories.

Herein we assess the phylogenetic relationships and taxonomy of geckos of the genus Phyllodactylus inhabiting the peninsula of Baja California, Mexico using five mitochondrial and two nuclear genes. Phylogenetic analysis using maximum parsimony (MP) and Bayesian inference (BI) recovered three distinct peninsular clades with high statistical support. Sequence divergence estimates between peninsular taxa approached 13%. Two of the species, P. unctus and P. xanti are Cape Region endemics, whereas P. nocticolus is widespread throughout much of the peninsula and extreme southern California. Monophyly of the peninsular taxa was strongly supported. In the MP analysis, P. unctus rooted at the base of the peninsular clade, resolving P. xanti and P. nocticolus as sister taxa. Conversely, BI placed P. nocticolus and P. unctus as sister taxa. These data provide further evidence for a trans-peninsular seaway near the Isthmus of La Paz, severing the Cape Region from the rest of the peninsula. The analysis also supports the validity of P. nocticolus as a distinct species and suggests a single invasion to the peninsula from mainland Mexico, presumably during tectonic activity during the Miocene.

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.

A new species of entomopathogenic fungi,Lecanicilliumcauligalbarum, was discovered from a survey of invertebrate-associated fungi in the Yao Ren National Forest Mountain Park in China. The synnemata of this species emerged from the corpse of a stemborer (Lepidoptera), which was hidden amongst pieces of wood on the forest floor. It differs from morphologically similarLecanicilliumspecies mainly in its short conidiogenous cells and ellipsoid to ovoid and aseptate conidia. Phylogenetic analysis of a combined data set comprising ITS,SSU,LSU,TEF,RPB1andRPB2sequence data supported the inclusion ofL.cauligalbarumin theLecanicilliumgenus and its recognition as a distinct species.

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.

A new species, Microthyrium propagulensis, collected in Yunnan Province, southwestern China is introduced. The species is typical of Microthyriaceae (Microthyriales) in having superficial thyriothecia with a poorly developed basal layer and a prominent darker central ostiole, bitunicate asci and 1-septate ascospores. It is similar to the generic type, M. microscopicum, but differs in having relatively small ascospores, with two apical cilia, which lie downloads from the ascospore apex at a 45° angle. Phylogenetic analysis based on combined LSU and SSU gene sequence data clearly place this species in Microthyrium, but distinguishes it from Microthyrium microscopicum. This second sequence from a Microthyrium species indicates that the putative sequence of the type of this genus is CBS has been correctly named and supports the distinctiveness of Microthyriales and Microthyriaceae.
