The plant-fungal interaction experiment showed that both genera had significant inhibitory effects on Arabidopsis thaliana, indicating their phytotoxicity potential on plants.

However, despite numerous records from Korea, Japan, and eastern China, no molecular phylogenetic studies have yet examined collections from these regions. The present study aims to clarify the species boundaries and geographic distribution of Cryptoporus in East Asia using integrative taxonomic approaches. Multilocus phylogenetic analyses were conducted using sequences from ITS, 28S, 18S, RPB2, and TEF1, together with species delimitation analyses. Our results demonstrate that East Asian collections represent a distinct lineage, herein described as a new species, Cryptoporus densiflorus. The new species is confirmed to occur in Korea and Japan and appears to be host-specific to Pinus densiflora. We reevaluate the geographic ranges of all currently accepted species and highlight that historical \"C. volvatus\" records in Asia include multiple taxa.

To date, 25 AGF genera have been described, but only five harbor more than one species. Here, we report on the isolation and characterization of novel AGF isolates from the feces of a Boer goat. The isolates formed small, mostly round, dense colonies on agar roll tubes and produced flaky, loosely clumped white biomass in liquid medium. Microscopic features included monoflagellated spherical zoospores and monocentric filamentous thallus. Sporangia were spherical or ovoid, although elongated and oddly shaped sporangia were also observed. Zoospore release was observed through ruptures in the sporangial wall. Phylogenetic analysis using the ribosomal internal transcribed spacer 1 (ITS1) and the 28S nuc rDNA D1-D2 region (28S) showed the isolates to be most closely related to Joblinomyces apicalis, the only described species in the genus Joblinomyces (0.00-1.30% divergence in ITS1, 2.50-3.82% in 28S). Transcriptomic sequencing and subsequent analysis of the RPB1 (largest subunit of RNA polymerase II) region and average amino acid identity (AAI) value comparison clearly showed a high level of AAI sequence divergence (70.11-75.40%, average 72.53 ± 1.43%) when compared with all other genera within the order Neocallimastigales.

The new species is morphologically distinct from other species of the genus Licea due to its well-developed capillitium threads connected to the peridial margins, minute sporocarps with dark brown spore mass, circumscissile dehiscence via preformed ridges, and spores with ephemeral, rounded warts that detach readily, creating irregularly smooth (\"bald\") patches. Apart from the morphological study, partial sequences of the nuclear ribosome small subunit 18S rRNA gene (18S nuc rDNA), mitochondrial cytochrome c oxidase subunit I gene (cox1), mitochondrial small subunit ribosomal gene (17S mt rDNA), and elongation factor-1 alpha gene (EF1α) were also provided. A multigene phylogenetic analysis places L. gorgona within the Lucisporomycetidae clade with other Licea species. We interpret capillitium in L. gorgona as plesiomorphic retention, contrasting with its apomorphic reduction in most other Licea species. Consequently, we propose revising the taxonomic diagnoses of the order Liceales and family Liceaceae to explicitly encompass species with a well-developed capillitium. However, due to the absence of molecular data for Listerella paradoxa and the majority of described Licea species, coupled with unconfirmed plasmodium morphology in L. paradoxa, we defer formal conclusions on the taxonomic status of Listerella and a comprehensive revision of the Licea circumscription.","PeriodicalId":18779,"journal":{"name":"Mycologia","volume":" ","pages":"1040-1063"},"PeriodicalIF":2.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148620675","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}

These fungi cause some of the most devastating diseases of agricultural crops worldwide. The mechanism of spore discharge is not well understood, despite its primary role in disease spread. Using confocal microscopy, we have elucidated the ascus structure and development as related to function for spore dispersal in Fusarium graminearum, a pathogen of small grains and corn. To determine the mechanism of spore discharge in this species, we examined ascus structure in both wild-type and spore discharge mutant strains and revealed the presence of two chambers within the ascus: a stiff-walled lower chamber that supports the developing spores and an upper chamber, extendable due to the presence of a chitin network across the surface that maintains the integrity of the sac as it is pressurized. The upper chamber includes an internal chute to confine and align the spores, while pressure builds up, with a minimum amount of fluid. Elucidation of the basis of spore dispersal for a member of this major group of fungi provides a solid beginning for exploring forcible discharge throughout this phylum. Previous studies have shown that the requirement for turgor is conserved, although the osmoticum may differ. This information will likely facilitate the development of new approaches to managing the spread of pathogenic species by targeting the very processes that allow them to efficiently colonize new environments.","PeriodicalId":18779,"journal":{"name":"Mycologia","volume":" ","pages":"1027-1039"},"PeriodicalIF":2.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148436994","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}

We evaluated the potential of F. xyrophilum to influence insect visitation patterns by (i) documenting insect visits to real flowers and pseudoflowers on X. surinamensis in the field in Guyana, (ii) assessing the presence of F. xyrophilum DNA on insect bodies, and (iii) analyzing volatile emissions from flowers and pseudoflowers. During our field work, a broad range of generalist insects (i.e. Vespidae, Formicidae, Salticidae, Acrididae, and Tetrigidae) visited the flowers and pseudoflowers, which notably shared some insect visitors (i.e. meadow katydids, carpenter ants, and geometer moths). Some of these insects were observed chewing on the flowers and pseudoflowers. Fusarium xyrophilum DNA was detected on the bodies of captured insects using conventional and quantitative polymerase chain reaction (PCR). Volatile profiles of pseudoflowers and flowers were largely similar, except for a sesquiterpene, putatively identified as α-gurjunene, which was emitted by pseudoflowers and pure cultures of F. xyrophilum but not Xyris flowers. These findings support the role of insect visitors as vectors of F. xyrophilum propagules and suggest that the fungus may attract and use generalist insects by exploiting their preexisting sensory biases for Xyris floral signals rather than true mimicry.","PeriodicalId":18779,"journal":{"name":"Mycologia","volume":" ","pages":"950-968"},"PeriodicalIF":2.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148211961","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}
