The cap resembles the cap of M. esculenta in its form and irregular pitting, but it is quite a little larger. The stem is very stout, much longer than the pileus, often very much wrinkled and folded. I have found only a few specimens of this species. Found in April and May.
Verpa. Swartz.
Verpa means a rod. Ascospore smooth or slightly wrinkled, free from the sides of the stem, attached at the tip of the stem, bell-shaped, thin; hymenium covering the entire surface of the ascospore; asci cylindrical, 8-spored. The spores are elliptical, hyaline; paraphyses septate.
The stem is inflated, stuffed, rather long, tapering downward.
Verpa digitaliformis. Pers.
Figure 417.—Verpa digitaliformis.
Digitaliformis is from digitus, a finger, and forma, a form.
The pileus is bell-shaped, attached to the tip of the stem, but otherwise free from it; olive-umber in color; smooth, thin, closely pressed to the stem, but always free; the edge sometimes inflexed.
