摘要
Three species of golden chanterelles were found in Newfoundland and Labrador and were compared with other Cantharellus species by macromorphology, microscopy, and multilocus phylogenetic studies. The commonest species is a member of the C. cibarius group, usually found with Picea, and is differentiated from European C. cibarius by its pinkish-orange rather than yellow hymenium, and from both C. cibarius and C. roseocanus of the Pacific Northwest by its ITS and TEF1 sequences. We describe it as a new species, Cantharellus enelensis; published sequences extend its range to Michigan and Illinois. An uncommon species with reduced, merulioid hymenophore, found growing only with Betula, has rDNA and TEF1 sequences nearly identical to C. amethysteus, but only occasionally shows the amethyst scales on its cap characterizing that species in Europe. Ours is the first report of this species from North America. A third species was recognized by its sequences as C. camphoratus, but our collections, found with Abies balsamea, lack the odour of camphor for which this species was named and have longer and more slender spores than in the original description. This species has not been reported since its description from a single collection in Nova Scotia. All three species are edible.
