Summary: The study collected over a hundred samples of plant debris from various freshwater locations in Spain and identified six new fungal species. Morphological comparison and phylogenetic analysis revealed that three strains belong to the family Didymellaceae and the remaining three strains belong to the family Phaeosphaeriaceae. The discovery of these new taxa significantly increases the number of coelomycetous fungi described from freshwater habitats.

Summary: Mycoparasitic fungi Ampelomyces are important for controlling plant pathogenic powdery mildews. The genomic analysis revealed the bipartite structure of Ampelomyces genomes and their evolutionary affinity to plant pathogenic fungi. The high-quality genome assembly provides a valuable resource for future studies on biocontrol mechanisms.

Summary: This article describes several saprobic ascomycetes belonging to the Periconia species that were collected in Yunnan, China. The researchers conducted a morphological analysis and obtained DNA sequence data to investigate their phylogenetic relationships. They introduced three new Periconia species and reported new host and geographical records of two other species. The study also discussed the relationship between Periconia celtidis and P. byssoides, as well as the synonymization of Bambusistroma under Periconia. The researchers provided detailed descriptions, illustrations, and an updated phylogenetic tree of Periconiaceae.

Summary: A new species of Parafenestella, named Parafenestella ontariensis sp. nov., was discovered from Acer negundo in Ontario, Canada. This study showed that the new species differs from existing species in terms of ascospore morphology, culture characteristics, and molecular data. Phylogenomic analysis also revealed a close relationship between this species and the fenestelloid clades of Cucurbitariaceae. Comparative genomics analysis indicated that the species has a multitrophic lifestyle and can potentially become pathogenic to its corresponding plant host.

Summary: Chromoblastomycosis is a neglected fungal infection predominantly found in tropical areas, caused by traumatic inoculation of environmental dematiaceous filamentous fungi. This case study presents an immunosuppressed patient diagnosed with foot chromoblastomycosis due to an uncommon dematiaceous fungus, which was successfully treated with excision surgery and liposomal amphotericin B therapy. The study highlights the potential diversity of environmental dematiaceous fungi responsible for phaeohyphomycosis, emphasizing the importance of accurate diagnosis through mycological examination.

Summary: Three new Helminthosporium species, H. guanshanense sp. nov., H. jiulianshanense sp. nov. and H. meilingense sp. nov., were discovered in southern China through morphological and molecular phylogenetic analyses. These species were found on dead branches of unidentified plants and were identified as independent taxa within Helminthosporium based on both molecular and morphological data.

Summary: The poorly known genus Immotthia has only two accepted species, and a new species, Immotthia bambusae, was discovered during research in southwest China and Thailand. Phylogenetic analyses revealed that Immotthia belongs to Dictyosporiaceae, while a new monotypic genus, Pseudocyclothyriella, is closely related to Immotthia.

Summary: Recent progress in fungal diversity discovery has largely relied on mycological surveys and DNA sequencing data analysis, which have led to an increase in new species descriptions. However, this rapid pace has resulted in oversight of previously documented species, highlighting the importance of morphology in accurate taxonomic classification.

Summary: During the investigation of microfungi from decaying wood in Sichuan Province, several novel fungal taxa of asexual and sexual morphs related to Pleosporales were discovered. Phylogenetic analyses based on gene sequences suggested that these new taxa were distributed in five families and justified the establishment of six new taxa. Among them, Neoangustimassarina was introduced as the second sexual morph genus in Amorosiaceae, and Bambusicola guttulata, O. sichuanensis and P. bambusicola contributed to the diversity of bambusicolous fungi. Detailed descriptions and notes for each new taxon, as well as a brief note for each family, were provided, along with a discussion on the potential richness of fungal diversity in Sichuan Province.
