KEY TO THE GENERA 
Sporophore broadly attached to the matrix ; the margin 
free and reflexed. 
Cartilaginous, ear-shaped, attached by a point. 
Sporophore cup-shaped, truncate, or irregularly lobed. 
Sporophore large, pulvinate, and gyrose. 
Sporophore brain-like or lobed. 
Sporophore convex, firm, with a central hard nucleus. 
Sporophore erect and spathulate. 
Hymenium with spines like a Hydnum. 
Sporophore small, pulvinate, and gyrose. 
Sporophore resembling a stalked Peziza. 
Sporophore irregularly cup-shaped, with the hymenium 
on one surface only ; substipitate. 
Irregularly cup-shaped, sessile, erumpent. 
Stem distinct; hymenium on expanded apex. 
AURICULARIA 
(From the supposed resemblance of some species to an ear, 
auricula) 
A. mesenterica (from the supposed resemblance of the 
hymenium to the mesenteric membrane). XXVI. 6. 
P. resupinate at first, then more or less reflexed, greyish- 
brown, zoned and velvety. H. brownish-violet, smooth or 
wrinkled, powdered with a beautiful bloom, inflated and 
gelatinous when moist, horny when dry. Frequent on old 
trunks and stumps of various trees, including yew and
