In an attempt to highlight lineages of fungi that are distinct from the most speciose subphylum Dikarya (Ascomycota + Basidiomycota), the terms \"early diverging fungi [lineages]\" and \"basal fungi\" have been introduced, typically to refer to any phylum of fungi outside Dikarya. However, these terms are problematic, because they implicitly assume that the traits and taxa outside of Dikarya are ancestral by invoking a \"ladder of progress.\" A simple rearrangement of the tree to deemphasize the species-rich Dikarya shows that the logic that these taxa are \"early branching\" or \"basal\" is a fallacy, because it ignores two facts: (i) that all extant lineages of fungi have evolved an equivalent amount of time since a last common fungal ancestor, and (ii) that the \"early diverging lineages\" are no more related to each other than they are to Dikarya. To support the many mycologists who want to celebrate the understudied lineages outside of Dikarya while ensuring that these lineages are not mistakenly perceived as \"less evolved,\" \"more ancient,\" or of \"lower complexity,\" we propose that the community abandon these terms and simply use formal taxonomic names, e.g. Mucoromycota. Doing so will promote knowledge of these often overlooked branches of the tree of fungal life.","PeriodicalId":18779,"journal":{"name":"Mycologia","volume":" ","pages":"246-254"},"PeriodicalIF":2.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11903137/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143527876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microbes are key drivers of many ecosystem processes and affect the fitness and resilience of plants and animals, but research on the biotic effects of urbanization has focused primarily on macroorganisms. This study investigates host-associated fungal communities in the pollution-tolerant aquatic plant Ranunculus aquatilis along an urbanization gradient in the Provo River, Utah, USA, a rapidly urbanizing region. We collected plant and adjacent water samples from 10 locations along the river, spanning from rural to urbanized areas within a single watershed, and conducted DNA amplicon sequencing to characterize fungal community composition. Our results show a significant decline in fungal alpha diversity correlated with increased urbanization metrics such as impervious surface area and developed land cover. Specifically, fungal richness and Shannon diversity decreased as urbanization intensified, driven primarily by a reduction in rare taxa. Despite a stable core microbiome dominated by a few taxa, the overall community structure varied significantly along the urbanization gradient, with notable shifts in dominant fungal taxa. Contrary to expectations, no detectable levels of heavy metals were found in water samples at any location, suggesting that other urbanization-related factors, potentially including organic pollutants or plant stress responses, influence fungal endophyte communities. Our findings underscore the need for further investigation into the mechanisms driving these patterns, particularly the roles of organic pollution, nutrient loads, and plant stress. As global urbanized watershed area grows, the fate of aquatic plant life is tied to their fungal community. Understanding these interactions is crucial for predicting the impacts of continued urbanization on freshwater ecosystems.","PeriodicalId":18779,"journal":{"name":"Mycologia","volume":" ","pages":"235-245"},"PeriodicalIF":2.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143523822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent observations support ericoid mycorrhizal lifestyles, especially in cultured Sarcoleotia-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 Sarcoleotia globosa, 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 S. globosa 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 S. globosa 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.","PeriodicalId":18779,"journal":{"name":"Mycologia","volume":" ","pages":"255-260"},"PeriodicalIF":2.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143391201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the morphological characteristics and multilocus phylogeny of the translation elongation factor-1 alpha (TEF1), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and the internal transcribed spacer (ITS-rDNA) genes, the studied isolates were assigned to five species, of which Curvularia caspica, sp. nov. and C. cyperi, sp. nov. are introduced as novel species and Curvularia nodulosa and C. oryzae are new records for Iran's mycobiota.

However, due to the absence of detailed morphological characteristics for C. frankliniae, morphological comparisons were not feasible. To precisely establish their phylogenetic position, more isolates need to be analyzed. Consequently, the studied species was identified as Curvularia sp. in this study.

Observations, but as well as metabarcoding of substrate samples with fungal (ITS [internal transcribed spacer]), bacterial (16S rDNA), and myxomycete (18S nuc rDNA) primers from eight trunks, revealed the new myxomycete to co-occur with resin-degrading ascomycetes (Infundichalara microchona, Lophium arboricola, Zythia resinae). The gram-negative bacterial genera Endobacter and Sphingomonas were found to be abundant in the substrate and may be a food source for the myxomycete. Fruit bodies were found mostly during the more humid winter season, with a peak in January/February. Partial sequences of two independent molecular markers (18S nuc rDNA, EF1α [elongation factor 1-alpha] gene) were obtained for 41 accessions, which form a monophyletic cluster in a two-gene phylogeny of Stemonititidales but do not group with other species of Diacheopsis, thus rendering this genus paraphyletic.
