Understanding the mechanisms by which pathogens such as Discula destructiva cause disease and losses in dogwoods, important forest plants and nursery ornamental crops, is crucial for developing effective management strategies. This study focuses on the enzymatic activities of D. destructiva, the causal agent of dogwood anthracnose, and their role in facilitating pathogenicity in Cornus spp. We hypothesized that D. destructiva produces higher levels of extracellular hydrolytic and oxidative enzymes compared with other Discula species, which could enhance its ability to invade and degrade host plant tissues. Our findings revealed that isolates of D. destructiva exhibit elevated enzymatic activities, specifically with abundant polyphenol oxidase activity. Additionally, we assessed the influence of environmental factors, such as pH and medium composition, on pathogen growth, demonstrated that optimal growth occurs at pH 4.5, whereas alkaline conditions inhibited growth dynamics. These insights suggest that managing environmental conditions or fungicide formulations could be an effective strategy for controlling the spread of dogwood anthracnose pathogen, thereby emphasizing the importance of enzymatic profiles in fungal pathogenicity.","PeriodicalId":18779,"journal":{"name":"Mycologia","volume":" ","pages":"615-628"},"PeriodicalIF":2.6,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144030096","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}

In response to these challenges, the present study investigates the potential of dark septate endophytes (DSEs) from Khawrihnim Village, Mizoram, India, to enhance the tolerance of upland rice (Oryza sativa). Two DSE species, Acrocalymma vagum and Alternaria chlamydospora, were identified and examined for their potential enhancement of plant resilience to salt and water scarcity stress. The result showed that both DSE species substantially impacted rice seed germination, biomass accumulation, and oxidative stress responses under salt and water scarcity conditions. Biomass content was augmented under elevated stress levels (-0.90 MPa), suggesting possible stress tolerance mechanisms. Increased superoxide dismutase activity and diminished malondialdehyde levels under stress conditions underscored the DSE's capacity to alleviate reactive oxygen species and lipid peroxidation in plants. Furthermore, seed and shoot germination rates were markedly enhanced by 60% using DSEs as biofertilizers, particularly evident in direct treatments. These findings highlight the efficacy of the DSEs Acrocalymma vagum and Alternaria chlamydospore as biofertilizers to enhance plant development and resilience in adverse environmental conditions. Their capacity to augment abiotic stress resilience and promote agricultural sustainability presents a significant opportunity for enhancing crop output, especially in areas susceptible to stress.","PeriodicalId":18779,"journal":{"name":"Mycologia","volume":" ","pages":"546-558"},"PeriodicalIF":2.6,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144033606","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}

A plethora of symbiotically active regulatory molecules are secreted throughout the continuum of ectomycorrhizal development, encompassing the period before physical contact between the fungi and their host plant roots to the maturation of the ectomycorrhizal symbiosis. However, our understanding of these substances is still limited. In recent years, as research in this field has deepened, several studies have documented that fungi release symbiotic regulatory substances, including fungal-derived plant hormones and small secreted proteins, which participate in the regulation of mycorrhizal formation. This article, from a fungal perspective, elaborates on the symbiotic regulatory substances secreted by ectomycorrhizal fungi into the surrounding environment or within the host plant. It further discusses the role of these substances in establishing symbiotic relationships with plants, aiming to offer novel insights for researchers in this field.","PeriodicalId":18779,"journal":{"name":"Mycologia","volume":" ","pages":"533-545"},"PeriodicalIF":2.6,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144151263","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}

Fungi are dominant carbon nutrient recyclers in ecosystems, but their roles in responding to and degrading these persistent fluorocarbons remain largely untapped. Here, we investigated the fungal species' responses to perflouroalkyl carboxylic acid (PFCA) chemicals and their capacities in breaking down C-F bonds for defluorination (deF) by using the ion-selective electrode for quantifying free fluoride anions and the 19F nuclear magnetic resonance (NMR) for monitoring PFAS removal in fungal cultures. Cytotoxicity assays showed that taxa within a unique class of fungi that cause \"white rot\" type of wood decay have developed an inherent defense mechanism for fluoride and fluorocarbon chemicals, setting off a basis for further investigating their deF phenotype. Although the current test did not evidence clear deF in legacy PFAS, including perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), it identified dehalogenated PFCA structures associated with an electron-attracting alkenyl group that provokes C-F cleavage. Our research, therefore, set a foundation for further unraveling the fungal deF mechanisms, and it also highlighted that future research should give sufficient attention to resident fungal communities in impacted environments due to their potential to recycle fluorinated compounds.","PeriodicalId":18779,"journal":{"name":"Mycologia","volume":" ","pages":"576-588"},"PeriodicalIF":2.6,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144209003","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}

The three genera are morphologically similar and characterized by resupinate to pileate basidiomes that harden and often darken upon drying, a monomitic hyphal structure, simple-septate generative hyphae, and globose to ovoid basidiospores, with variable presence of cystidia. Species in Henningsia and Meripilus, in turn, present gloeopleurous hyphae in the context and large, multipileate basidiomes. Recent studies have indicated that Physisporinus, as currently defined, is not monophyletic, with Meripilus nested within it. Phylogenetic analysis based on four molecular markers confirmed the paraphyletic nature of Physisporinus, with Meripilus and Henningsia both nested within it. Morphological examinations of specimens collected in South America, along with revisions of type specimens, show that this segregation is not natural and causes nomenclatural problems. We propose to transfer all species currently placed in Physisporinus into Meripilus, thereby preventing the division of the genus into morphologically indistinguishable groups.

Although this pathogen was described more than a century ago infecting Momordica charantia, its taxonomic positioning has not yet been clarified. Moreover, a standard isolate of this fungus is not available in any reference mycological collection. In this context, the aims of the present work were (i) to clarify the taxonomic position of the fungus via morphological and phylogenetic analyses; (ii) to deposit a neotype of L. momordicae in a public mycological collection; (iii) to provide the first DNA sequences of the pathogen in GenBank. The morphometrical characteristics of distinct L. momordicae isolates were similar to those originally described. The phylogenetic analyses were carried out using information of five genomic regions. Using the BLASTn algorithm, it was observed that the L. momordicae-derived sequences displayed higher identity levels to fungal sequences of the order Pleosporales, which were subsequently included in the analyses. All sequences from the nine isolates of L. momordicae grouped within a single phylogenetic clade distinct from the other taxa in Pleosporales. Therefore, it is suggested the establishment of a new family of Pleosporales to include L. momordicae to which the name Leandriaceae is proposed. In addition, an ex-neotype and a neotype were illustrated and deposited in the Herbarium of the Federal University of Viçosa (VIC4754) and in the culture collection \"Octávio Almeida Drummond\" (COAD3403).
