The plethora of in lakes of the northwestern Yunnan plateau, China.

The diversity of lignicolous freshwater fungi in northwestern Yunnan, China, has been studied for several years in the College of Agriculture and Biological Science, at Dali University. Over the last 5 years, we published two new genera and nine new species of from northwestern Yunnan. This study focused on introducing tubeufia-like hyphomycetous fungi found in freshwater lakes in the northwestern Yunnan plateau.

Novel Species and Records of from Freshwater Habitats in China and Thailand.

China and Thailand are rich in fungal diversity with abundant freshwater resources that are favorable for numerous fungal encounters. Resulting from this, the majority of the species reported were from these two countries. During the investigation on the diversity of lignicolous freshwater fungi in the Greater Mekong Subregion, eleven collections of cheirosporous species on submerged wood were collected from lentic and lotic habitats in China and Thailand.

Yunnan Province is one of the rich biodiversity hotspots with abundant resources of lignicolous freshwater fungi. A total of 281 species of lignicolous freshwater fungi from 1986 to the present in Yunnan Province. They are mostly distributed in the classes and , a few species in the and , and rarely reported in and .

Three New Species, Two New Records and Four New Collections of Tubeufiaceae from Thailand and China.

Tubeufiaceae, a cosmopolitan family with a worldwide distribution, is mostly reported as saprobic on decaying woody materials from both aquatic and terrestrial habitats. The family is commonly found as helicosporous hyphomycetes, while some are chlamydosporous and phragmosporous. In this study, thirteen helicosporous hyphomycetes were collected from Thailand and China.

Two new species of from leaf spots of in north-western Yunnan Province, China.

Background: During the survey of pathogenic fungi on medicinal plant leaves in Yunnan Province, China, two -like taxa were isolated from leaf spots of . Based on morphological characteristics and phylogenetic analysis of combined ITS, TEF1-α and ACT genes, two new species were discovered.

New Information: Two new species and are introduced, the detailed descriptions and illustrations are provided.

Fungal diversity notes 1512-1610: taxonomic and phylogenetic contributions on genera and species of fungal taxa.

This article is the 14th in the Fungal Diversity Notes series, wherein we report 98 taxa distributed in two phyla, seven classes, 26 orders and 50 families which are described and illustrated. Taxa in this study were collected from Australia, Brazil, Burkina Faso, Chile, China, Cyprus, Egypt, France, French Guiana, India, Indonesia, Italy, Laos, Mexico, Russia, Sri Lanka, Thailand, and Vietnam. There are 59 new taxa, 39 new hosts and new geographical distributions with one new combination.

Fungal diversity notes 1387-1511: taxonomic and phylogenetic contributions on genera and species of fungal taxa.

This article is the 13th contribution in the Fungal Diversity Notes series, wherein 125 taxa from four phyla, ten classes, 31 orders, 69 families, 92 genera and three genera are treated, demonstrating worldwide and geographic distribution. Fungal taxa described and illustrated in the present study include three new genera, 69 new species, one new combination, one reference specimen and 51 new records on new hosts and new geographical distributions. Three new genera, (), ( genus ) and () are introduced based on distinct phylogenetic lineages and unique morphologies.

Two novel species and two new records of from freshwater habitats in China and Thailand.

During investigations into freshwater fungi from the Great Mekong Subregion, four taxa were collected from China and Thailand. Based on morphological characteristics, and phylogenetic analyses of combined LSU, ITS, SSU, TEF1-α, and RPB2 sequence data, two new species and are introduced, and two known species and were first reported in freshwater habitat. Illustrations and descriptions of these taxa are provided, along with comparisons with extant taxa in the genus.

Two new species of and a new record, from freshwater habitats in China.

Background: Pleosporales is the largest order of Dothideomycetes. In recent years, systematics of Pleosporales have undergone considerable revisions. Dictyosporiaceae is one of the newly established families within this order proposed to accommodate holomorphic saprobic Dothideomycetes.

One New Species and Two New Host Records of from Bamboo and Maize in Northern Thailand with Thirteen New Combinations.

The genus is known as a cosmopolitan genus, found across various substrates. In this study, four taxa were obtained from the decaying stems of bamboo and maize in northern Thailand. collections were compared with known species based on the morphological characteristics and the DNA sequence data of internal transcribed spacer (ITS), the partial large subunit nuclear rDNA (LSU), the translation elongation factor 1-alpha gene (TEF1-α) and beta-tubulins (TUB2).

Biodiversity of Lignicolous Freshwater Hyphomycetes from China and Thailand and Description of Sixteen Species.

Freshwater hyphomycetes are a highly diverse group of fungi with a worldwide distribution and have been mostly reported from tropical and subtropical regions. During investigations of freshwater fungi from the Greater Mekong subregion in China and Thailand, sixteen freshwater hyphomycetes (three of them belong to the class Dothideomycetes while thirteen belong to the class Sordariomycetes) were collected. Based on morphology and multi-gene phylogenetic analyses, , , , , and are described as new species; is proposed as a new combination; , , , , and are reported as new country records; and , and are introduced as three new collections.
