Balsamia (Sequestrate Helvellaceae, Ascomycota) in western North America
Balsamia, a hypogeous, sequestrate genus in the Helvellaceae, has been characterized variously as having three to eight species in North America, and these have been considered either different from or conspecific with European species. No available modern systematic
treatment of Balsamia exists to allow for accurate identification at the species level. We sequenced DNA from recent western North American Balsamia collections, assessed relationships by sequence similarity, and identified molecular taxonomic units. From these data, we determined
which matched descriptions and types of named species. ITS sequences supported 12 Balsamia species in western North America, five originally described by Harkness and Fischer and seven new species that we describe here. No sequences from Balsamia collections in western North
America were nested among those of European species. We found no clear evidence for separation of Balsamia into multiple genera.

- Fungal Systematics and Evolution is an international, peer-reviewed, open-access, full colour, fast-track journal. Papers will include reviews, research articles, methodology papers, taxonomic monographs, and the description of fungi. The journal strongly supports good practice policies, and requires voucher specimens to be deposited in a fungarium, cultures in long-term genetic resource collection, sequences in GenBank, alignments in TreeBASE, and taxonomic novelties in MycoBank.
