Identification of two new species and a new host record of (Distoseptisporaceae, Distoseptisporales, Sordariomycetes) from terrestrial and freshwater habitats in Southern China.

During our investigation of saprophytic fungi in Guizhou and Hainan provinces, China, three hyphomycetes were collected from terrestrial and freshwater habitats. Based on morphological characteristics and phylogenetic analyses of combined ITS, LSU, 1-α, and 2 sequence data, two new species are introduced: and . Additionally, one known species, , previously unreported from , is newly reported.

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.

Two new fungal genera () found on in Thailand.

is a species-rich order of fungi that includes endophytes, saprobes, and pathogens associated with forest plants and crops. They may also occur as parasites or secondary invaders of plant tissues injured or infected by other organisms or inhabit living animal and human tissues, as well as soil. Meanwhile, some severe pathogens wipe out large-scale cultivations of profitable crops, timber monocultures, and forests.

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.

Morphological and Phylogenetic Analyses Reveal Five New Species in Chaetosphaeriaceae.

Chaetosphaeriaceae is a genera-rich and highly diverse group of fungi with a worldwide distribution in terrestrial and aquatic habitats. Eight fresh collections of Chaetosphaeriaceae were obtained during investigations of hyaline-spored hyphomycetes in China and Thailand. Based on morphological characteristics and phylogenetic analysis of a combined LSU and ITS sequence dataset, , , , and were introduced as new species, was reported as new host record, and and were introduced as new collections.

Fungi are the major decomposers in terrestrial and aquatic ecosystems, playing essential roles in biogeochemical cycles and food webs. The Fungi kingdom encompasses a diverse array of taxa that often form intimate relationships with other organisms, including plants, insects, algae, cyanobacteria and even other fungi. Fungal parasites of insects are known as entomopathogenic fungi and are the causative agents of serious disease and/or mortality of their hosts.

The genus .

species have a wide host range and an extensive distribution. Some species are associated with rusts, as well as other plant pathogenic fungi and play an important role in biological control. In this study, two specimens of were collected from Chiang Mai Province, Thailand.

Two new entomopathogenic species of in Thailand.

is entomopathogenic and the largest studied genus in the family . Many species in this genus have been reported from Thailand. The first new species introduced in this paper, , differs from other species based on its smaller perithecia, shorter asci and secondary ascospores and additionally, in parasitising fly species.
