species at first somewhat resembles Polyporus vaporarius, but 
it is a true Hydnum, and very distinct, though difficult to de- 
fine in words.

On sticks, &c. Common. 
Pileus effused behind, with the margin reflected, about 1 
inch long and several inches in breadth from the confluence 
of many individuals. Coriaceous, rather rigid zoned clothed 
with a short hairy pile, often plicate in young specimens, of 
à rich brown, becoming grey in the older parts, or when the 
outer coat has vanished dark brown. Hymenium cracked, 
smooth, reddish-brown, with frequently a flesh-coloured 
bloom. 
This species is intermediate between S. purpureum and s. 
spadiceum, but is distinct from either. The hymenium is 
nearly of the same colour with that of S. quercimum with 
a beautiful flesh-coloured bloom.

Pilei 3 lines broad, effused behind, with the lobed convex 
border reflected, tawny umber, zoned clothed with short, 
hispid pubescence. Hymenium smooth, pruinose, of a yel- 
lowish grey, frequently proliferous. It is only in perfect 
Specimens that the zones are visible. This is a minute and 
species, but cannot be confounded with others. The 
Specimens, though so small have passed through every stage 
of growth. In age it becomes bleached. oe
