Morphological and phylogenetic analyses reveal three new species and one new record of (Tubeufiales, Tubeufiaceae) from southern China.

During an investigation of helicosporous fungi in China, a total of seven helicosporous hyphomycetes were obtained from decaying wood in the southern region of the country. Based on phylogenetic analyses using a combined LSU, ITS, , and sequence matrix, in conjunction with morphological comparisons, these taxa were classified within (Tubeufiaceae, Tubeufiales) and were recognized as three new species, , , and , as well as one new distribution record, . Evidence for these new taxa and the new record, descriptions, illustrations, notes, and phylogenetic evidence are provided for the newly collected helicosporous species.

Additions to the Genus (Tubeufiaceae, Tubeufiales) from China with an Identification Key for Taxa.

Helicosporous hyphomycetes is a group of filamentous fungi that shows promising application prospects in metabolizing bioactive natural compounds. During a study of helicosporous fungi in China, six new helicosporous taxa were collected and isolated from decaying wood in Guangxi Zhuang Autonomous Region, China. Morphological comparisons with multi-gene phylogenetic analyses revealed that these six taxa belong to (Tubeufiaceae, Tubeufiales), and they were recognized as three novel species and were named and .

Morphological and Multi-Gene Phylogenetic Analyses Reveal gen. nov. and Two New Species in Tubeufiaceae from China.

Three helicosporous hyphomycete collections representing two species were obtained from rotting wood found in freshwater and terrestrial habitats in the Guizhou and Guangxi Provinces, China. A new genus (Tubeufiaceae, Tubeufiales), comprising . sp.

Neogrisphenol A, a Potential Ovarian Cancer Inhibitor from a New Record Fungus .

From the rice fermentation product of a new record fungus, , two new polyketides, neogrisphenol A () and neogrisphenol B (), one new isochroman-1-one, ()-6-hydroxy-7-methoxy-3,5-dimethylisochroman-1-one (), and four known compounds (-) were isolated. Their structures were determined using 1D- and 2D-NMR, mass spectrometry, and chemical calculations. The C-3~C-2' polymerization mode between the two -naphthalenone derivative moieties is uncommon in compounds and .

Four new species and three new records of helicosporous hyphomycetes from China and their multi-gene phylogenies.

Helicosporous hyphomycetes have the potential to produce a variety of bioactive compounds. However, the strain resources of this fungal group are relatively scarce, which limits their further exploitation and utilization. In this study, based on phylogenetic analyses of combined ITS, LSU, RPB2, and TEF1α sequence data and the morphology from 11 isolates, we introduce four new species of helicosporous hyphomycetes, , and , as well as three new records, , and .

Multi-Gene Phylogenetic Analyses Revealed Five New Species and Two New Records of from China.

Eight hyphomycetes were collected as part of an investigation into the diversity of hyphomycetous fungi in China. Based on morphology and multi-loci (LSU, ITS, tef1α, and rpb2) phylogenetic analyses, five new taxa, including a new Aquapteridospora species A. hyalina and four novel Distoseptispora species, viz D.
