ochraceous cuticle. Substance white, uniform. Pores about two 
es long, minute, white within and without, not at all stratose, 
slightly angular, with thin dissepiments and a rather irregular edge. 
Nearly allied to P. officinalis, but the pores are smaller, pure white, 
and not at all stratose, nor is the flesh bitter when dry, or easily re- 
duced to powder. With P. betulinus also it has a very close affinity, 
but differs in habit, having no tendency to become spuriously stipitate, 
nor has the cuticle the brown tinge or minutely scabrous appearance 
of that species.

vertex which is elongated into a short stem, cinnamon clouded with 
white, slightly downy. Hymenium deus but sunk beneath the swollen 
margin, cinnamon ; pores very minu 
This has precisely the habit of medias cupuleformis, Schwein. It 
is allied to P. pullus, Mont. and Berk. It is probably not uncommon. 
Dr. Léveillé has received it from a higher part of America.

Thin, membranaceous; pileus flabelliform, variously lobed, 2—4 
inches long, pale, silky, at length nearly smooth, and shining, repeat- 
edly but delicately zoned. Hymenium white; pores small, dissepi- 
ments very thin and delicate, soon torn, and toothed so as to give the 
plant the appearance of a Hydnum. 
Closely allied to P. elongatus, Beck., but more delicate and shini 
and differing essentially in the long membranaceous hydnoid teeth into 
which the dissepiments are broken up at an early stage of growth. In 
the South Carolina. plant this character is even stronger than in that
