A re-evaluation of Diaporthe: refining the boundaries of species and species complexes

Fungal Diversity, Journal Year: 2024, Volume and Issue: 126(1), P. 1 - 125

Published: July 9, 2024

Abstract Diaporthe is an important plant pathogenic genus, which also occurs as endophytes and saprobes. Many species that are morphologically similar proved to be genetically distinct. The current understanding of taxonomy by applying morphological characters, host associations multi-gene phylogeny problematic leading overestimation/underestimation numbers this significant fungal genus. Currently, there no definite boundaries for the accepted species. Hence, present study aims re-structure genus , based on single gene phylogenies (ITS, tef tub cal his ), justified GCPSR (Genealogical Concordance Phylogenetic Species Recognition) methodology well coalescence-based models (PTP—Poisson Tree Processes mPTP—multi-rate Poisson Processes). Considering all available type isolates divided into seven sections while 13 15 species-complexes proposed. To support re-assessment 82 obtained from woody hosts in Guizhou Province China were investigated revealed presence two novel 17 previously known Synonymies specified 31 molecular data studies. Dividing several specific phylogenetic analyses can avoid construction lengthy trees entire future taxonomic In other words, when one conducts research related only appropriate section need selected analysis.

Phylogenetic and Morphological Analyses Reveal Twelve New Species of the Genus Patellaria (Dothideomycetes, Ascomycota) from Mexico

Journal of Fungi, Journal Year: 2025, Volume and Issue: 11(1), P. 44 - 44

Published: Jan. 7, 2025

Patellaria species are widely distributed in terrestrial and marine habitats saprobes growing on decaying wood, stems, or bark. However, studies this genus Mexico limited, only the type atrata Fr. has been cited. This study describes twelve new supported by molecular (ITS-LSU-SSU) morphological data. Phylogenetic analysis shows that of not closely related to atrata. Moreover, results demonstrate greatest diversity is found dry climates, particularly xerophilous scrub.

Two novel hyphomycetes associated with ferns from China

MycoKeys, Journal Year: 2025, Volume and Issue: 113, P. 101 - 121

Published: Jan. 31, 2025

During an ongoing investigation of fungi associated with ferns in southwestern China, three hyphomycetes were discovered on the dead rachises Angiopterisfokiensis and unidentified fern. Based morphology multi-gene phylogenetic analyses, Arthrobotrysangiopteridis Corynesporaseptata are introduced as new species. is a nematode-trapping fungus characterized by macronematous, mononematous, hyaline conidiophores, conidiogenous cells polyblastic denticles at each node, 0-1-septate, clavate to elongate pyriform, conidia. features pale brown dark integrated, monotretic up 7-distoseptate one true septum, subcylindrical obclavate, Detailed descriptions illustrations these two species provided, along morphological comparisons taxa closely related

Three novel species and a new record of Pleosporales (Didymellaceae, Roussoellaceae) from China

MycoKeys, Journal Year: 2025, Volume and Issue: 113, P. 295 - 320

Published: Feb. 12, 2025

We are investigating saprobic Ascomycota in Guizhou Province, China. Fungal specimens collected from dead wood were identified based on morphological characteristics and multi-gene phylogenetic analyses of ITS, SSU, LSU, β-tubulin, ef1-α, rpb2 sequence data. Three novel species, Neoroussoellaguizhouensis, Roussoellaguizhouensis, Xenodidymellaguizhouensis, introduced, along with one new geographical record, Xenoroussoellatriseptata. This study contributes to our understanding the diversity Province classification Roussoellaceae.

Yunnan Province is rich in freshwater resources, providing a favorable environment for fungi. As result, numerous new species have been described recent years, further supporting the extensive diversity of fungi this region. During an investigation lignicolous from Dulongjiang River, six fresh isolates Dictyosporiaceae were obtained. The collection includes two ( Dictyocheirospora splendida and Jalapriya guttulata ), records D. nabanheensis Dictyosporium hughesii one known duliujiangense ). They are introduced based on morphological evidence molecular phylogenetic analysis combined ITS, LSU, tef 1-α sequence data.

Myochromella unveiled: exploring its global distribution through a public database of amplicons

BMC Microbiology, Journal Year: 2025, Volume and Issue: 25(1)

Published: May 24, 2025

Myochromella mammosa, a novel species from southwestern China, is distinguished by its small, solitary or gregarious basidiomata. The pileus clock-shaped, with distinct central mastoids, edge stripes, and darker center that flattens upon maturation. stipe white, firm when young, becomes hollow slightly thickened at the base age. We conducted comprehensive analysis of publicly available ITS sequences NCBI-GenBank fungal amplicon sequencing data NCBI-SRA to explore global distribution enumeration recorded Myochromella. At 98% sequence similarity threshold, eleven were identified, including eight without formal designations. Myochromella's diversity primarily Northern Hemisphere-centric tends toward endemic distribution. Leveraging sets enables precise assessments, enhancing field collection efficiency providing insights into macrofungal diversity.
