Morchella americana
Morchella americana is a species of fungus in the family Morchellaceae native to North America. Described as new to science in 2012, it is common east of the Rocky Mountains in a range stretching from Ontario south to Texas, Arkansas, Alabama, Georgia and South Carolina. In western North America, the species typically is found under hardwood, especially cottonwood trees in river bottoms, or with apple trees or ornamental ashes in urban settings. The specific epithet "americana" refers to its occurrence in North America. In the Great Lakes region of eastern North America, the range of "M. americana" overlaps  with "M. ulmaria", which cannot be reliably distinguished from "M. americana" without DNA sampling. "Morchella 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. In 2014, Richard et al. clarified the taxonomic status of this species, retaining the name "Morchella americana" of Clowez and Matherly(2012) over "M. esculentoides".
