Morchella americana (also called the yellow morel)[1] is a North American species of fungus in the family Morchellaceae.

Taxonomy

In the Great Lakes region of eastern North America, the range of M. americana overlaps with M. ulmaria; the two species cannot be reliably distinguished without DNA sampling.[2] Other similar species include M. diminutiva, M. prava and others in the genus, in addition to Verpa bohemica and Gyromitra species.[1]

The species was described as new to science in 2012. In 2014, Richard et al. clarified its taxonomic status, retaining the name Morchella americana of Clowez and Matherly (2012) over M. esculentoides.[3][4]

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.[5][3]

Etymology

The specific epithet americana refers to the species' occurrence in North America.

Distribution and habitat

The species 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.
