Previously reported collections from other areas of Atlantic Canada, and from high elevations in the southern Appalachians, were small and poorly developed. It had been suggested that these might represent a distinct, undescribed species. However, the morphology and chemistry of the collections reported here confirm the identity of the Newfoundland population as E. mollissimum.
