Morchella populiphila is a species of morel fungus (family Morchellaceae) native to northwestern North America. Described as new to science in 2012, its specific epithet refers to its association with black cottonwood (Populus trichocarpa). The morel used to be referred to as Morchella semilibera in western North American field guides until molecular analysis established that to be a strictly European species. M. populiphila occurs in California, Nevada and Oregon. Its fruit bodies grow up to 15 cm (6 in) tall with a ridged and pitted conical cap that attaches about halfway down the stipe.

Morchella septentrionalis species of fungus in the family Morchellaceae native North America. Described as new to science in 2012, it has a northerly eastern North American distribution, where it occurs north of 44°N. The fungus fruits under hardwoods, particularly American aspen (Populus grandidentata) and American ash (Fraxinus americana).

Morchella prava is a species of fungus in the family Morchellaceae described as new to science in 2012. It is found in the range 43–50°N across North America, where it fruits from April to June.

Morchella ulmaria is a species of fungus in the family Morchellaceae. It was described as new to science in 2012 by Philippe Clowez. Later in the same year, Michael Kuo and colleagues described Morchella cryptica, which is a junior synonym of M. ulmaria. The species occurs in the forests of Midwestern North America, often associated with white ash (Fraxinus americana), the American tulip tree (Liriodendron tulipifera) or species of maple or elm. It is closely related to M. castanea and 2 unnamed species from Asia. The range of M. ulmaria overlaps with M. americana, which cannot be reliably
