Abbreviation for “section.”
A section is a taxonomic rank below genus, but above species. The subgenus, if present, is higher than the section, and the rank of series, if present, is below the section. Sections may in turn be divided into subsections.
Sections are typically used to help organise very large genera, which may have hundreds of species. A mycologist wanting to distinguish groups of species may prefer to create a taxon at the rank of section or series to avoid making new combinations, (i.e. many new binomial names for the species involved).
A series is a subdivision of a genus, a taxonomic rank below that of section (and subsection) but above that of species.
