Collections of Bionectriaceae and Nectriaceae from Henan, Hubei and Guangdong provinces, China, were examined. Three new species, Neonectria confusa, N. shennongjiana and N. sinensis, are described and illustrated. Distinctions between the new species and their related taxa are discussed. Phylogenetic relationships among some Neonectria species are(More)
DNA phylogenetic comparisons have shown that morphology-based species recognition often underestimates fungal diversity. Therefore, the need for accurate DNA sequence data, tied to both correct taxonomic names and clearly annotated specimen data, has never been greater. Furthermore, the growing number of molecular ecology and microbiome projects using(More)
The type specimens of Auerswaldia, Auerswaldiella, Barriopsis, Botryosphaeria, Leptoguignardia, Melanops, Neodeightonia, Phaeobotryon, Phaeobotryosphaeria, Phyllachorella, Pyrenostigme, Saccharata, Sivanesania, Spencermartinsia and Vestergrenia were examined and fresh specimens of Botryosphaeriales were collected from Thailand. This material is used to(More)
With the recent changes concerning pleomorphic fungi in the new International Code of Nomenclature for algae, fungi, and plants (ICN), it is necessary to propose the acceptance or protection of sexual morph-typified or asexual morph-typified generic names that do not have priority, or to propose the rejection or suppression of competing names. In addition,(More)
Collections of bionectriaceous fungi from different areas of China were examined, in which 3 new species were encountered. Bionectria intermedia is characterized by smooth perithecia, 2-layered perithecial wall, cylindrical to clavate asci with an apical ring, ascospore striations composed of separate warts, and dimorphic conidiophores. Hydropisphaera(More)
A new species, Hymenoscyphus albidoides, is described based on materials collected from eastern China. Sequences of the new species form a well-supported clade in the phylogenetic trees inferred from either the individual ITS, calmodulin gene and β-tubulin gene, or combined ITS and calmodulin gene, as well as combined ITS, calmodulin and β-tubulin genes.(More)
An abundance of novel fungal lineages have been indicated by DNA sequencing of the nuclear ribosomal ITS region from environmental samples such as soil and wood. Although phylogenetic analysis of these novel lineages is a key component of unveiling the structure and diversity of complex communities, such analyses are rare for environmental ITS data due to(More)
Partial sequences (about 600 nucleotides) of the calmodulin gene were used for the phylogenetic studies on Eupenicillium, Talaromyces and Penicillium. This region is from the 3rd base of the codon for the 9th amino acid Gln to the 3rd base of the codon for the 122th amino acid Val, flanking parts of the 2nd and 5th exons with complete sequences of two exons(More)
Four new species of Hymenoscyphus (H. brevicellulus, H. hyaloexcipulus, H. microcaudatus, and H. subsymmetricus) and a new Chinese record (H. subpallescens) are described. These five species share common characteristics: small apothecia (<3 mm in diameter); hymenium whitish, pale yellow, to yellow in color; ectal excipulum of textura prismatica; asci(More)
BACKGROUND RNA secondary structure is highly conserved throughout evolution. The higher order structure is fundamental in establishing important structure-function relationships. Nucleotide sequences from ribosomal RNA (rRNA) genes have made a great contribution to our understanding of Ascomycota phylogeny. However, filling the gaps between molecular(More)
