Hab. In the same places as the preceding, and in this 
country much more common. Autumn. 
Desc. Size the same as the preceding, but more prone 
to monstrosity. Pileus quite free, generally more or 
less lobed, or even crisped and curled ; upper surface 
yellowish-white, pale-brownish beneath. Stem some- 
what ventricose towards the base, deeply lacunose^ 
white, often very thick. 
The Helvetia are very similar to the Morelles as articles 
of food, and, like the Morelles and the Truffles, there 
are no poisonous species. According to Allioni, H. mitra 
is eaten in Piemont ; and De Canbolle mentions having 
seen an analogous species (probably H. leucophcea), used 
in the environs of Aignes-mortes under the name of oi'eil- 
lette. — Essai sur les Proprietes Med. des Plantes, p. 324. 
On the authority of Peiisoon, it is employed in the 
neighbourhood of Paris in the same way as Morelles. The 
same author has also a remark, that the larger Pezizie may 
be eaten without fear, and prepared in the same manner.
