Naming
In 2014, Richard et al. clarified the taxonomic status of this species, retaining the name "Morchella americana" of Clowez over "M. esculentoides".The specific epithet "americana" refers to its occurrence in North America.
Distribution
In the Great Lakes region of eastern North America, the range of "M. americana" overlaps with "M. cryptica", which cannot be reliably distinguished from "M. americana" without DNA sampling."M. americana", identified as phylogenetic species "Mes-4", has also been found in Turkey, France, and Germany, but is suspected of having been introduced there from North America.
Habitat
In western North America, the species typically is found under hardwood trees in river bottoms, or with apple trees or ornamental ashes in urban settings.References:
