Two new species of Endocarpon (Verrucariaceae, Ascomycota) from China.

ABSTRACT: Endocarpon species are key components of biological soil crusts. Phenotypic and systematic molecular analyses were carried out to identify samples of Endocarpon collected from the southeast edge of the Tengger Desert in China. These morphological and molecular analyses revealed two previously undescribed species that form highly supported independent monophyletic clades within Endocarpon. The new taxa were named Endocarpon deserticola sp. nov. and E. unifoliatum sp. nov. Furthermore, our results indicated that the newly developed protein coding markers adenylate kinase (ADK) and ubiquitin-conjugating enzyme h (UCEH) are useful for assessing species boundaries in phylogenic analyses.

Two new asexual genera and six new asexual species in the family Microthyriaceae (Dothideomycetes, Ascomycota) from China.

Project description:The family Microthyriaceae is represented by relatively few mycelial cultures and DNA sequences; as a result, the taxonomy and classification of this group of organisms remain poorly understood. During the investigation of the diversity of aquatic hyphomycetes from southern China, several isolates were collected. These isolates were cultured and sequenced and a BLAST search of its LSU sequences against data in GenBank revealed that the closest related taxa are in the genus Microthyrium. Phylogenetic analyses, based on the combined sequence data from the internal transcribed spacers (ITS) and the large subunit (LSU), revealed that these isolates represent eight new taxa in Microthyriaceae, including two new genera, Antidactylaria gen. nov. and Isthmomyces gen. nov. and six new species, Antidactylariaminifimbriata sp. nov., Isthmomycesoxysporus sp. nov., I.dissimilis sp. nov., I.macrosporus sp. nov., Triscelophorusanisopterioideus sp. nov. and T.sinensis sp. nov. These new taxa are described, illustrated for their morphologies and compared with similar taxa. In addition, two new combinations are proposed in this family.

Three New Species of Clonostachys (Hypocreales, Ascomycota) from China.

Project description:Three new species of Clonostachys are introduced based on specimens collected from China. Clonostachys chongqingensis sp. nov. is distinguished by pale yellow to pale orange-yellow perithecia with a very low papilla, clavate to subcylindrical asci possessing ellipsoidal to elongate-ellipsoidal spinulose ascospores 13-16 × 4.5-5.5 μm; it has acremonium- to verticillium-like conidiophores and ellipsoidal to rod-shaped conidia. Clonostachys leptoderma sp. nov. has pinkish-white subglobose to globose perithecia on a well-developed stroma and with a thin perithecial wall, clavate to subcylindrical asci with ellipsoidal to elongate-ellipsoidal spinulose ascospores 7.5-11 × 2.5-3.5 μm; it produces verticillium-like conidiophores and ellipsoidal to subellipsoidal conidia. Clonostachys oligospora sp. nov. features solitary to gregarious perithecia with a papilla, clavate asci containing 6-8 smooth-walled ascospores 9-17 × 3-5.5 μm; it forms verticillium-like conidiophores and sparse, subfusiform conidia. The morphological characteristics and phylogenetic analyses of combined nuclear ribosomal DNA ITS1-5.8S-ITS2 and beta-tubulin sequences support their placement in Clonostachys and their classification as new to science. Distinctions between the novel taxa and their close relatives are compared herein.

Morphological and molecular identification of two new Alternaria species (Ascomycota, Pleosporaceae) in section Radicina from China.

Project description:The fungal genus Alternaria was distributed widely and found in different habitats such as plant or indoor environment. During an investigation into this genus in China, two new Alternaria species, Alternaria vulgarae and A. divaricatae were respectively isolated from diseased leaves of Foeniculum vulgare and Saposhnikovia divaricata, which both belonged to Umbelliferae. Phylogenetically, they were determined as new species belonging in the section Radicina of Alternaria based on the combined four gene fragments of ITS, TEF1, GAPDH and RPB2. Morphologically, the two species were illustrated and compared with other relevant Alternaria species in section Radicina.

Neodactylariales, Neodactylariaceae (Dothideomycetes, Ascomycota): new order and family, with a new species from China.

Project description:During a mycological survey of aquatic hyphomycetes on submerged decaying leaves in southwest China, a distinct new fungus was collected. The collection was cultured and sequenced and a BLAST search of its ITS and LSU sequence against data in GenBank revealed a dothideomycetous affiliation, with the closest related taxa in the genus Neodactylaria. Phylogenetic analyses of a multigene matrix containing sequences from four genes (LSU, SSU, rpb2, and tef1), representing broad groups of Dothideomycetes, revealed its placement within Dothideomycetes, but without a supported familial or ordinal affiliation. Based on further phylogenetic analyses and morphological investigations, the new fungus is described here as a new species of Neodactylaria, N. simaoensis sp. nov., and placed in a new family Neodactylariaceaefam. nov. and a new order Neodactylarialesord. nov.

New Species of Neocosmospora (Ascomycota) from China as Evidenced by Morphological and Molecular Data.

Project description:Species of Neocosmospora are commonly found in soil, plant debris, and living woody or herbaceous substrates and occasionally found in water and air. Some species are reported as saprobes, endophytes, opportunistic pathogens of plants and animals, or producers of bioactive natural products, cytotoxic compounds, and industrial enzymes. To reveal the species diversity of Neocosmospora, specimens from different provinces of China were investigated. Five new species, Neocosmospora anhuiensis, N. aurantia, N. dimorpha, N. galbana, and N. maoershanica, were introduced based on morphological characteristics and DNA sequence analyses of combined calmodulin (CAM), the internal transcribed spacer (ITS), the second largest subunit of RNA polymerase II (RPB2), and the translation elongation factor 1-α (TEF1) regions. Differences between these new species and their close relatives are compared in detail.

Genome characteristics reveal the impact of lichenization on lichen-forming fungus Endocarpon pusillum Hedwig (Verrucariales, Ascomycota).

Project description:BACKGROUND:Lichen is a classic mutualistic organism and the lichenization is one of the fungal symbioses. The lichen-forming fungus Endocarpon pusillum is living in symbiosis with the green alga Diplosphaera chodatii Bialsuknia as a lichen in the arid regions. RESULTS:454 and Illumina technologies were used to sequence the genome of E. pusillum. A total of 9,285 genes were annotated in the 37.5 Mb genome of E. pusillum. Analyses of the genes provided direct molecular evidence for certain natural characteristics, such as homothallic reproduction and drought-tolerance. Comparative genomics analysis indicated that the expansion and contraction of some protein families in the E. pusillum genome reflect the specific relationship with its photosynthetic partner (D. chodatii). Co-culture experiments using the lichen-forming fungus E. pusillum and its algal partner allowed the functional identification of genes involved in the nitrogen and carbon transfer between both symbionts, and three lectins without signal peptide domains were found to be essential for the symbiotic recognition in the lichen; interestingly, the ratio of the biomass of both lichen-forming fungus and its photosynthetic partner and their contact time were found to be important for the interaction between these two symbionts. CONCLUSIONS:The present study lays a genomic analysis of the lichen-forming fungus E. pusillum for demonstrating its general biological features and the traits of the interaction between this fungus and its photosynthetic partner D. chodatii, and will provide research basis for investigating the nature of its drought resistance and symbiosis.

Two new species of Verruconis from Hainan, China.

Project description:Two new species of the genus Verruconis, V.hainanensis and V.pseudotricladiata, were described using combined morphological and DNA sequence data. The DNA sequences of respective strains including nuclear ribosomal DNA genes (nuSSU, ITS, nuLSU) and fragments of three protein-coding genes (ACT1, BT2, TEF1) were sequenced and compared with those from closely-related species to genera Ochroconis and Verruconis (Family Sympoventuriaceae, Order Venturiales). Morphologically, both species showed typical ampulliform conidiophores and conidiogenous cells, features not seen in other species of Verruconis. The conidia of V.hainanensis are fusiform and those of V.pseudotricladiata are Y or T shaped, similar to old members of a closely-related genus Scolecobasidium. The addition of these two new species provides a new perspective on the heterogeneity of Scolecobasidium.
