MycoKeys publishes papers on the monophyletic kingdom Fungi containing taxonomic or ecological data on any taxon of any geological age from any part of the world with no limit to manuscript size.

MycoKeys will consider for publishing: descriptions of new taxa, if they are accompanied with proper diagnoses and/or keys to distinguish them from close relatives or similar taxa, and if DNA sequence data are deposited in Genbank prior to publication; taxonomic revisions of extant (or ‘’recent’’) and fossil fungal groups; checklists and catalogues; phylogenetic and evolutionary analyses, if alignments are deposited in TreeBase; papers in descriptive and/or historical biogeography; methodology papers, including description of new software, if released a open source license and released as supplementary material to the article; data mining and literature surveys; monographs, conspecti, atlases; primer notes; “Points of View” commentaries; collections of papers, Festschrift volumes, conference proceedings; data papers.

Extensive overviews on a taxon in a country or larger region are welcome. Short mycological contributions may be considered if they are based on significant or unexpected discoveries. Regular contributions may eventually be published in special issues devoted to a region/country.
