Still, if you cut it lengthwise, a hollow cylinder extends from the top to the bottom of the mushroom.
The irregular longitudinal ribs are brown to blackish, the pits are beige.
The whitish, scruffy, faintly ribbed stalk is 3-1/4 to 4 inches long, 3/8 to 3/4 inches wide, with a thickened base.
This mushroom grows in open hardwood forests throughout North America in the spring.
Not as flavorful as other morel species, this one is still a good edible.
