MUSHROOMS, EDIBLE AND OTHERWISE 



The plants in the figure were found near Columbus and photographed by 

 Dr. Kellerman. I have not found the plant as far south as Chillicothe, though 

 I found it frequently in the northern part of the state. It grows in the woods 

 on leaf-mould. 



Helvetia lacunosa. Afs. 

 The Cinereous Helveela. 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 charac- 

 teristic of this species. The 

 plants from which the half- 

 tone was made were collected 

 near Sandusky and photo- 

 graphed by Dr. Kellerman. 

 They grow in moist woods. I 

 found the plants frequently in 

 the woods near Bowling Green 

 and occasionally about Chilli- 

 cothe, growing about well- 

 decayed stumps. 



Hypomyces. Tul. 



Hypomyces means upon a mushroom, 

 byssoid ; perithecia small ; asci 8-spored. 



It is parasitic on fungi. Mycelium
