title: <b>Tree Diversity Reduces Soil Carbon Temperature Sensitivity</b>

description: The temperature sensitivity of soil carbon decomposition (Q₁₀) is a key determinant of terrestrial carbon–climate feedbacks under global warming. However, the mechanisms through which tree species diversity modulates Q₁₀ remain poorly understood. Using a long-term biodiversity manipulation experiment in a subtropical forest, we investigated how increasing tree species richness affects Q₁₀ by altering soil carbon stabilization processes and microbial functional composition. We found that tree species richness significantly reduced Q₁₀, reflecting enhanced soil carbon stability. This effect was mediated by increased accumulation of chemically recalcitrant compounds and a higher proportion of mineral-associated organic matter. In parallel, tree species richness induced functional shifts in microbial communities, particularly fungi, favoring saprotrophic taxa and increasing the relative abundance of microbial Y-strategists—organisms characterized by high growth efficiency and low respiratory carbon loss. These microbial functional shifts promote rapid assimilation and stabilization of soil labile carbon, contributing to slower carbon turnover and reduced Q₁₀. Together, our results demonstrate that tree species richness enhances soil carbon retention and mitigates climate feedbacks by restructuring microbial strategies and promoting long-term carbon stabilization pathways.

title: Cold and dehydration tolerance of Belgica antarctica from three distinct geographic locations

description: In this study, we measured cold and dehydration tolerance of larvae of Belgica antarctica from three distinct geographic locations along the Antarctic Peninsula. Larvae were collected from Cape Rasmussen, Cape Evensen, and Dream Island, after which they were returned to the US for experiments. For cold tolerance, larvae were exposed to -14 or -15°C for 24 h, and survival was assessed 24 later. For dehydration tolerance, larvae were exposed to 75% RH for 72 h, and survival was checked after 24 h of rehydration. The dataset reports the numbers of live and dead larvae from each island and experimental conditions. Larvae were tested in groups of 10.

title: The genus <i>Hermatomyces</i> in Benin, with the description of <i>H. griseomarginatus</i>, sp. nov.

description: Intensive mycological surveys in southern Benin focused on species of <i>Hermatomyces</i> (Pleosporales) resulted in the collection and sequencing of numerous specimens on dead plant debris of different hosts. Majority of the collections belonged to the monomorphic species <i>H. sphaericus</i>, except for two specimens of a hitherto unknown species, which is introduced as <i>Hermatomyces griseomarginatus</i>. The fungus was collected on dead twig of <i>Hymenocardia acida</i> still attached to the tree and dead peduncle of <i>Tectona grandis</i>. It is distinct in having sporodochia with a dense and dark gray margin enclosing their lenticular conidia. Phylogenetically, it formed a well-supported lineage sister to two other monomorphic species, <i>H. verrucosus</i> and <i>H. sphaericoides</i>. Two dimorphic species were also found, <i>H. krabiensis</i> and <i>H. nabanheensis</i>, which are reported for the first time outside of Asia. Detailed morphological descriptions are provided, and the diversity of <i>Hermatomyces</i> in Benin is summarized based on published data and results from the GlobalFungi database.

title: Psychrophilic fungi from the world’s roof, II: Species delimitation within an integrative taxonomic framework

description: Southeast Qinghai-Tibet Plateau, which harbors large numbers of marine glaciers and spans across two worldwide “biodiversity hotspots,” is facing massive habitat loss in the context of global warming, and the biodiversity of coldadapted fungi in this unique area is also suffering drastic reduction. In this study, we selected 23 fungal isolates that represented the most commonly encountered psychrophilic taxa isolated from soil or water samples of marine glaciers in the southeast Qinghai-Tibet Plateau for detailed taxonomic studies. Incorporating morphological characteristics, multilocus phylogenetic analyses, and the results of four widely used molecular species delimitation methods, including two distance-based: Automatic Barcode Gap Discovery (ABGD) and Assemble Species by Automatic Partitioning (ASAP), and two tree-based: Bayesian Poisson Tree Processes (bPTP) and generalized mixed Yule coalescent model (GMYC), seven <i>Gelida</i> (formerly <i>Psychrophila</i>) species, including six new species, and two <i>Tetracladium</i> species, including one new species, were described. As the genus name <i>Psychrophila</i> is an illegitimate later homonym of a plant genus, we proposed the new name <i>Gelida</i> as a replacement for <i>Psychrophila</i> and transferred four illegitimate <i>Psychrophila</i> species to <i>Gelida</i> as new combinations. Our study provides a valuable perspective on how to delimit robust and accurate species boundaries within an integrative taxonomic framework, which is especially important for efficient biodiversity assessment and conservation of the fungal groups that are facing serious habitat loss.

title: Morphological and molecular characterization of <i>Curvularia</i> species from Iran, with description of two novel species and two new records

description: <i>Curvularia</i> species exhibit a wide range of ecological roles, including plant, animal, or human pathogens, as well as epiphytes, saprophytes, or endophytes, predominantly associated with cultivated cereals. In this study, several fungal isolates with similar characteristics in the genus <i>Curvularia</i> were recovered from various poaceous hosts (Poales plants) in different locations in Iran during 2012‒2022. Based on the morphological characteristics and multilocus phylogeny of the translation elongation factor-1 alpha (<i>TEF1</i>), glyceraldehyde-3-phosphate dehydrogenase (<i>GAPDH</i>), and the internal transcribed spacer (ITS-rDNA) genes, the studied isolates were assigned to five species, of which <i>Curvularia caspica</i>, sp. nov. and <i>C. cyperi</i>, sp. nov. are introduced as novel species and <i>Curvularia nodulosa</i> and <i>C. oryzae</i> are new records for Iran’s mycobiota. Molecular studies revealed a closer relationship between one of the studied species (<i>Curvularia</i> sp.) and <i>C. frankliniae</i>. However, due to the absence of detailed morphological characteristics for <i>C. frankliniae</i>, morphological comparisons were not feasible. To precisely establish their phylogenetic position, more isolates need to be analyzed. Consequently, the studied species was identified as <i>Curvularia</i> sp. in this study. Additionally, a new clade, “papendorfii,” was established to accommodate 11 species that share common morphological characteristics and form a distinct clade in phylogenetic analyses. The morphology, habitat, distribution, and evolutionary relationships of each species with other <i>Curvularia</i> species were analyzed, accompanied by detailed illustrations and descriptions. This comprehensive study offers valuable insights into the diversity and distribution of <i>Curvularia</i> species, enhancing our understanding of fungal ecology and taxonomy.

title: Does the genome of <i>Sarcoleotia globosa</i> encode a rich carbohydrate-active enzyme gene repertoire?

description: The lifestyles of the order Geoglossales (Geoglossomycetes, Ascomycota) remain largely unknown. Recent observations support ericoid mycorrhizal lifestyles, especially in cultured <i>Sarcoleotia</i>-related species. However, the currently known genomes of geoglossoid fungi encode fewer carbohydrate-active enzymes (CAZymes) in Pezizomycotina, in contrast to the abundant CAZyme repertoires found in well-known ericoid mycorrhizal fungi. The absence of assembled genomes for cultured geoglossoid fungi hinders our understanding of the genomic features related to their lifestyles. We hypothesize that the genome of <i>Sarcoleotia globosa</i>, a putative ericoid mycorrhizal fungus, encodes abundant CAZymes, consistent with its culturability. General features, such as smaller genome size and smaller number of genes, are shared between the genome of <i>S. globosa</i> strain NBRC 116039 and other geoglossalean genomes. However, the former had the most extensive CAZyme repertoire, with several enzyme families involved in plant cell wall degradation. Some of these CAZymes are not found in Geoglossales and closely related lineages. Nonetheless, the number of CAZymes from <i>S. globosa</i> was notably smaller than that previously reported in ericoid mycorrhizal fungi. This inconsistency may highlight not only ecophysiological variation among ericoid root mycobionts but also the specific evolution of lifestyles in Geoglossales.

title: Aquatic <i>Xylaria</i>: an exotic fungus introduced into the United States on aquarium decorative wood

description: This study examined fungi with <i>Xylaria</i>-like morphology on submerged decorative wood in freshwater aquariums in Minnesota and Colorado. The wood was sold in retail stores in the United States but originated from Asia. The submerged wood had black stromatic melanized structures with white tips that grew out from the wood. As colonization progressed, the fungus produced more melanized structures along the entire length of the wood and moved to new wood placed in the aquariums. Cut segments from the fungal structures and from the colonized wood were cultured in malt extract agar supplemented with antibiotics. Pure cultures obtained were used for DNA extraction, and polymerase chain reaction (PCR) amplification was performed using ITS1F-ITS4. Sequences were compared against the National Center for Biotechnology Information (NCBI) nucleotide database using BLASTn. Isolates from the fungal structures and wood obtained from the Minnesota and Colorado aquariums were all found to be <i>Xylaria apoda</i>, a fungus not previously reported from the United States. Phylogenetic analysis shows that the aquarium isolates of <i>Xylaria</i> cluster within a well-supported clade of <i>Xylaria apoda</i>. These <i>Xylaria</i> had grown in a completely aquatic habitat, producing fruiting body–like structures for several years in the freshwater aquariums. Asexual spores were not observed but may have been disseminated into the water as they are formed. Asci and ascospores were also not observed. <i>Xylaria apoda</i> has been reported only from Asia, and it is usually found in terrestrial habitats. This report adds to our knowledge of <i>Xylaria</i> that can grow in a completely underwater environment and focuses attention on an avenue for exotic fungi to be brought into new countries where they are not native. These results also contribute to the growing body of evidence that <i>X. apoda</i> is an ecologically versatile species, capable of thriving in diverse environments, including artificial habitats such as freshwater aquariums.
