sinuous ; hymenium even. There are twelve British species, of 

 which the two commonest are represented 

 by models. Most of the species are 

 reputed edible. Some grow in spring, 

 others in autumn. 



179. Helvella crispa Fr. — Pileus de- 

 flexed, lobed, free, undulate and contorted, 

 very pale brown ; stalk fistulose, deepl}' 

 ribbed and lacunose, white. 



H. crispa is not uncommon in woods 

 and by damp, grassy roadsides near 

 hedges. Edible, but with little flavour 

 and very tough ; it is best for the table 

 when slowly stewed in white sauce. 



180. Helvella elastica Bull. — Pileus 

 orbicular, sometimes twice or thrice lobed, 

 free, even, inflated ; stalk at lirst stuffed, 

 then hollow, pruinose, thickened at base, 

 sometimes slightly lacunose. 



H. elastica grows in moist places in 

 woods and on shady, bushy banks.
