Special Issue Information

Dear Colleagues,

Marine fungi play crucial roles in energy flow and nutrient recycling in marine ecosystems, as well as in the marine food web. They are major decomposers of woody and herbaceous substrates and animal carcasses or their parts, therefore mediating the cycling of dissolved organic matter in marine ecosystems. In addition, marine fungi are important pathogens of phytoplankton and zooplankton and are implicated in diverse interactions with other marine microbes. However, despite their ecological significance and potential applications, marine mycology represents a vital yet relatively underexplored aspect of marine biology. Fortunately, recent advances in high-throughput sequencing technologies and genomic and metabolomic approaches are enabling the discovery of a considerable amount of previously undisclosed knowledge regarding marine mycology in various marine habitats, such as coral reefs, mangroves, sediments, and deep-sea environments. Emerging investigators in the field of marine mycology include growing communities of researchers focusing on various aspects of marine fungi, such as biodiversity, phylogenetic relationships, taxonomy, ecological roles, biogeography and distribution, fungal–microbe interactions, biotechnology and its applications, and temporal community dynamics under global climate change. Understanding these emerging studies is essential for the sustainable monitoring and preservation of biodiversity and marine ecosystem functioning.

The following Special Issue aims to compile interesting and inspiring studies by emerging investigators that delve into these important trends in marine mycology. We welcome submissions of original research articles and review papers that advance our understanding of marine fungal diversity, ecology, taxonomy, biogeography, community stability, biotechnology, fungal–microbe interactions, biochemistry, and conservation. It is our hope that this collection will provide deep insights into marine mycology and inspire further investigations and collaboration in this field.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Fungi is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Marine fungi are pivotal components of coastal ecosystems, facilitating essential biogeochemical cycling and trophic dynamics. However, the complex mechanisms governing their spatiotemporal community patterns in tropical–subtropical coasts remain largely unexplored. In this study, we characterized marine fungal diversity across a comprehensive seasonal cycle (spring (March), summer (June), autumn (August), and winter (December)) at 21 representative sites along the Leizhou Peninsula, China. These sites were strategically selected to encompass a broad range of dissolved inorganic nitrogen (DIN) gradients. Fungal community composition was characterized via high-throughput sequencing of the internal transcribed spacer 2 (ITS2) region, followed by functional guild profiling using the FUNGuild database. A total of 8777 amplicon sequence variants (ASVs) were identified, encompassing a broad taxonomic breadth of 10 phyla and 358 genera. Ascomycota, Basidiomycota, and Chytridiomycota emerged as the predominant phyla across all samples. Our results revealed significant spatiotemporal heterogeneities: seasonal succession fundamentally reshaped community composition, with DIN exerting its most pronounced influence during the winter. Furthermore, fungal functional structures exhibited distinctive clustering across regions defined by DIN enrichment levels. Co-occurrence network analysis revealed a highly modular and robust architecture, characterized by predominantly positive interactions and dense inter-taxon connectivity. These findings underscore the synergistic influence of temporal dynamics and DIN enrichment in shaping marine fungal community assembly and functional compositions. Our study provides critical baseline insights into the ecological resilience of coastal mycobiota in the South China Sea. Full article
