Helvellaeeee 



HELVEL'LA Linn. 

 A small pot herb. 



Heiveiia. Stem of medium thickness. Pileus hanging loosely over the stem, 

 more or less folded, but not into pits. Hymenium on the upper side 

 only. 



Helvetia esculenta is now Gyromitra esculenta, and is in bad repute. 



Meanings of the unfamiliar words are too lengthy to give in the de- 

 scriptions of species. They are in the Glossary. 



Dr. Badham says: "All Helvellae are esculent, have an agreeable 

 odor, and bear a general resemblance in flavor to the Morell."

 torted, white or whitish. Stem
