Supplementary files for "Notulae Clavariacearum III. Clavaria lumbriciformis sp. nov. and other Western North American Collections in the Clavaria fragilis Complex"

The most abundant species of the Clavaria fragilis complex in western North America is described as a new species: Clavaria lumbriciformis. It is closely related to the type of the genus but can be differentiated based on spore dimensions, habitat, geographic distribution, and phylogenetic placement. Several much less frequently collected, closely related putative species are discussed.
