The Cinereous Helvella. Edible.
Figure 421.—Helvella lacunosa.
Lacunosa, full of pits or pitted. This is a beautiful plant, very closely related to the Morchellas.
The pileus is inflated, lobed, cinereous black, lobes deflected, adnate.
The stem is hollow, white or dusky, exterior ribbed, forming intervening cavities.
The asci are cylindrical, and stemmed. The sporidia are ovate and hyaline.
The deep longitudinal grooves in the stem are characteristic of this species. The plants from which the halftone was made were collected near Sandusky and photographed by Dr. Kellerman. They grow in moist woods. I found the plants frequently in the woods near Bowling Green and occasionally about Chillicothe, growing about well-decayed stumps.
