Addition of Five Novel Fungal Flora to the Xylariomycetidae (Sordariomycetes, Ascomycota) in Northern Thailand.

The deviation of conventional fungal niches is an important factor in the implications of hidden fungal diversity and global fungal numbers. The Xylariomycetidae (Sordariomycetes, Ascomycota), which is also referred to as xylarialean taxa, has a wide range of species that demonstrate a high degree of variation in their stromatic characteristics, showing either conspicuous or inconspicuous forms. In this study, samples were collected while focusing on temporal and spatial parameters and substrate characteristics.

Re-Evaluating : Ancestral State Reconstructions of Selected Characters and Evolution of Nutritional Modes.

(, ) occur in a wide range of habitats as endophytes, saprobes, and pathogens. The order has not been subjected to evaluation since 2019 by Phillips and co-authors using phylogenetic and evolutionary analyses. Subsequently, many studies introduced novel taxa into the order and revised several families separately.

Taxonomy and Phylogeny of Fungi Associated with from Yunnan, China.

During investigations of saprobic fungi associated with mango () in Baoshan and Honghe of Yunnan Province (China), fungal taxa belonging to the orders Botryosphaeriales, Calosphaeriales, Chaetothyriales, Diaporthales, and Xylariales were recorded. Morphological examinations coupled with phylogenetic analyses of multigene sequences (ITS, LSU, SSU, , , β-tubulin and CAL) were used to identify the fungal taxa. A new genus viz.

Identification and Pathogenicity of Species Associated with Leaf Spot Disease in Northern Thailand.

Species of that are reported as plant pathogens and cause leaf spot or leaf blight have been reported on many commercial crops worldwide. In 2019, during a survey of fungi causing leaf spots on plants in Chiang Mai and Mae Hong Son provinces, northern Thailand, 16 isolates from 14 host species across nine plant families were collected. A new species sp.

Morpho-molecular characterisation of , with and sp. nov. and comb. nov.

Three arecophila-like fungal samples were collected on dead culms of gramineous plants in China. Morphological studies of our new collections and the herbarium specimen of (generic type) were conducted and the morphological affinity of our new collections with was confirmed. Maximum likelihood and Bayesian analyses using combined ITS, LSU, 2 and β-tubulin data from our collections revealed the phylogeny of .

Three new species of (Xylariomycetidae): , and .

Three fungal specimens (two sexual and one asexual) were collected during fieldwork conducted in China, Taiwan and Thailand. Both sexual morphs share superficial, black ascomata surrounded by flexuous setae; 8-spored, unitunicate, cylindrical asci, with J+, apical ring, and ellipsoidal to allantoid, aseptate, guttulate ascospores. The asexual morph has ceratosporium-like conidia arising from aerial hyphae with a single arm and are usually attached or with 2-3 arms, brown, often with a subglobose to conical cell at the point of attachment.

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.

Morphology and Phylogeny Reveal fam. nov. (, ) with Two Novel Species.

Phylogenetic analyses of combined , rpb2, tub2 and sequence data of representative taxa indicated that , and cluster together and form a distinct clade in . Morphological comparison also shows their distinctiveness from other families of . Therefore, we introduce it as a novel family, .

sp. nov. (Herpotrichiellaceae, Chaetothyriales, Eurotiomycetes) from submerged bamboo in China.

Background: Freshwater fungi are highly diverse and ecologically important in freshwater systems. In China, more than 1000 species of freshwater fungi are known. Here, we present a brown-spored hyphomycetes that was collected on a submerged decaying bamboo culm in a forest stream in China.

sp. nov. and an updated key to the species of (Myriangiaceae, Dothideomycetes).

Background: belongs to Dothideomycetes and its members are epiphytic on living bamboo culms or palms and distributed in tropical regions. Currently, the genus comprises seven species. Another collection resembling was collected from the leaves of sp.

Multigene Phylogeny Reveals gen. et sp. nov. and Familial Replacement of (Xylariales, Sordariomycetes, Ascomycota).

During our investigation of palm fungi in Thailand, two interesting taxa from and (Arecaceae) were collected. Based on phylogenetic analyses of a combined dataset of ITS, LSU, , and nucleotide sequences as well as unique morphological characteristics, we introduce the new genus within Xylariales, and a new species . Additionally, in our study, the genus is transferred to the family Cainiaceae based on its brown conidia and molecular phylogenetic evidence.

gen. et sp. nov. and sp. nov. (Diatrypaceae) from China.

Background: In this study, we introduce a novel genus, , of the family Diatrypaceae comprising three species viz. sp. nov.

Molecular Phylogeny and Morphology of (= ) (Amphisphaeriaceae).

Amphisphaeriaceous taxa (fungi) are saprobes on decaying wood in terrestrial, mangrove, and freshwater habitats. The generic boundaries of the family have traditionally been based on morphology, and the delimitation of genera has always been challenging. species have clypeate ascomata and 1-septate ascospores and a coelomycetous asexual morph.
