Species delimitations, specimens, and GenBank accessions.

’Species Name ABGD delimitation’ is a unique name applied to a clade within Galerina that is delimited by ABGD software; specimens with the same ABGD group number are in the same putative species. ABGD delimitations are only available for clades within Galerina and for ITS sequences > 500 bp. ’Specimen ID’ designates the collection; under ’Toxin?’ +TOX indicates that amatoxins were detected, -TOX indicates no amatoxins detected; ’Country’ is the two-digit code for country of collection; ’Section’ refers to infrageneric taxon of Galerina; ’Taxon #’ is an arbitrary specimen tracking number also used in supplementary figures; ’Original ID’ is the species name originally applied to the herbarium collection or to the sequence.
