Morchella tomentosa, commonly called the gray, fuzzy foot, or black foot morel, is a species of fungus in the Morchellaceae family.^[2] M. tomentosa is a fire-associated species described from western North America, formally described as new to science in 2008.^[1]

Morchella tomentosa is identified by its post-fire occurrence, fine hairs on the surface of young fruit bodies, and a thick, "double-walled" stem.^[1][3] It also has unique sclerotia-like underground parts.^[4] Color can range from black and "sooty" to gray, brown, yellow, or white, although color tends to progress from darker to lighter with age of the fruiting body.^[2]

Phylogeny and relationships of Morchella tomentosa and related species based on ITS ribosomal DNA sequences.[4]

Based on studies of DNA, M. tomentosa is clearly a distinct species apart from the yellow morels (M. esculenta & ssp.) and black morels (M. elata & ssp.).^[4] Mushroom collectors also use the common name "gray morel" for M. esculenta-type morels in eastern North America.^[2]
