Sydowia publishes reports of original research relevant to fungal taxonomy, systematics, evolution, structure, development, ecology, pathology (plants, animals, humans), and biotechnological applications. Reviews are published in areas of particular interest and current importance, but authors should consult the Editor before submitting a review manuscript. One volume of the journal, comprising two issues, is published each year. The official journal language is English. Submission of a manuscript to the Executive Editor implies that the results have not been previously published or simultaneously submitted to any other scientific journal, except as an abstract. When the authors are in doubt as to the suitability of their papers for Sydowia, the Editor of the journal should be consulted before submission of the manuscript.

All authors of a manuscript must have agreed to its submission and are responsible for its content. An author is one who has substantially contributed to the overall design and execution of the experiments. Individuals who supplied materials or critiqued the paper may be recognised in the acknowledgement section.
