lobed, undulate, 1–3 inches wide, rugose and pitted with thick, raised, tortuous, intertwined ribs, although scarcely forming areolae small open spaces, tawny-spadiceous date-brown, villous and whitish underneath, the margin here and there adnate to the stipe. Of good flavor, frequent in food, but of less value than Morchella esculenta. Frequent in the pine forests of mountainous regions, in bare, somewhat moist places, especially along the sandy sides of roads. "It seems to appear in most abundant quantity every third year" A. S. March to May. (seen alive)

It is intermediate between the Morchellas (in terms of fleshy substance and costate pileus) and the Mitras, included here especially because of its affinity with H. infula etc. Its entire history, flavor, odor, location, time, duration, and use are those of the Morchellas; even the common people count it among the Morchellas: to the Swedes it is Stenmurkla, to the Germans Gemeine Morchel (Gled), Stumpf Morchel (A. S.), Stockmorchel (Dierbach). Menzel was also the first discoverer, who distinguished it very well from H. infula and placed it among the Morchellas. Gleditsch, while joining it with our remaining Helvellas, separates this one alone. More recent authors, however, as Linnaeus himself did, more often confuse it with H. Mitra b. — H. esculenta Fl. Dan. t. 1559 is rather a form of Helv. pulla.
