Craterellus fallax, a Black Trumpet mushroom from eastern North America with a broad host range.

Phylogenetic analysis of ITS sequences of members of the Craterellus cornucopioides complex (Black Trumpet mushrooms) supports the taxonomic separation of Craterellus fallax apart from C. cornucopioides, with which it has been synonymized in the past. Examination of Pinus virginiana ectomycorrhizal (ECM) root tips and sequence comparison with other insufficiently identified environmental sequences from roots of Tsuga, Quercus, and possibly Castanea supports a broad host range in North America for the ECM symbiont C.
