Summary: This study collected plant debris submerged in freshwater from different locations in Spain, developing new species of freshwater ascomycetes. Through phylogenetic analysis, new species of Amniculicola, Elongatopedicellata, Neovaginatispora, Pyrenochaetopsis, Pilidium, and Pseudosigmoidea were identified. These findings contribute to the understanding of the diversity and taxonomy of freshwater ascomycetes.

Summary: This study reviewed the species diversity of the Pezicula genus in China and discovered two new species and two new Chinese records. Descriptions and illustrations were provided for the new species, and phylogenetic analysis confirmed their placement in the genus based on ITS nrDNA sequences.

Summary: A study found that temperature plays an important role in microbial-mediated leaf degradation in streams experiencing intermittency. During short dry periods, aquatic fungal communities invest in energetically-expensive physiological responses to desiccation, while longer drought periods result in lower fungal diversity and negative effects on fungal growth and reproductive capacity. Native riparian vegetation plays a critical role in protecting freshwater ecosystems from intensified drought periods in intermittently flowing streams.

Summary: Thelebolales are globally distributed fungi with diverse ecological characteristics. This study introduces two new taxa, based on morphological and phylogenetic analyses. The phylogenetic analyses showed that these new taxa formed distinct lineages separate from other members of Thelebolales. These new taxa did not form sexual structures. The phylogenetic relationships and morphological differences between these new taxa and other species in Thelebolales are also discussed.

Summary: This study investigated the diversity, taxonomy, and phylogeny of chalara-like fungal species in China. Based on a systematic study using literature research, morphological observation, and phylogenetic analyses, it was found that these fungi belong to 20 accepted genera in five families of Leotiomycetes. The study also discovered many new species and provided identification keys for most of these genera.

Summary: This study provides important insights into the impacts of nanoplastic particles on leaf litter decomposition and aquatic hyphomycetes communities in forested streams. The results indicate that the concentration and size of nanoplastic particles significantly affect leaf litter decomposition, fungal sporulation, and the abundance of aquatic hyphomycetes. However, the impact on leaf litter nutritional quality is primarily influenced by particle size.

Summary: Co-contamination of freshwaters by nanoplastics and metals affects the cellular and physiological activities of aquatic fungi. Functionalised nanoplastics enhance metal adsorption, leading to reactive oxygen species accumulation and plasma membrane disruption. The impact of metals on fungal growth depends on their co-existence with nanoplastics.

Summary: A novel endophytic fungus was discovered in the roots of a medicinal plant in Southern China and identified as a new species based on morphological and molecular analysis. A new isocoumarin and 12 known compounds were isolated from the rice fermentation products of this fungus. Unfortunately, none of these compounds showed significant antitumor activity.

Summary: During the investigation, 15 collections of lignicolous freshwater fungi were isolated from submerged decaying wood in the Tibetan Plateau habitat. These fungi display characteristic punctiform or powdery colonies with dark pigmented and muriform conidia. Phylogenetic analysis of their DNA sequences revealed that they belong to three families in Pleosporales. Out of these, four species were identified as new species, while three species were reported as new records in the freshwater habitats of Tibetan Plateau, China. This study provides morphological descriptions and illustrations of the new collections.

Summary: The study found that under oligotrophic conditions, litter quality has a more significant impact on the performance and decomposition rate of microbial decomposers, while temperature has minimal influence on the studied variables. The decrease in litter quality associated with global change in the future is expected to have a major impact on stream ecosystem functioning.

Summary: The study found that drought has a significant impact on microbial-mediated decomposition processes, leading to decreased efficiency in fungal communities and affecting stream functioning. Aquatic hyphomycetes play a vital role in litter decomposition in dry streambeds following slower habitat contraction patterns.

Summary: Three new species of Distoseptispora, namely D. mengsongensis, D. nabanheensis, and D. sinensis, were identified and illustrated based on specimens collected from unidentified plants in Yunnan Province, China. Phylogenetic analyses using LSU, ITS, and TEF1 sequence data confirmed the taxonomic placement of these three new taxa within Distoseptispora. Both morphological observations and molecular phylogenetic analyses supported the recognition of D. mengsongensis, D. nabanheensis, and D. sinensis as distinct species. Additionally, a list of recognized species of Distoseptispora, including major morphological features, habitat, host, and locality, was provided to enhance our understanding of the diversity of Distoseptispora-like fungi.
