DECADES OF FUNGI. 137 



This species is very near to P, Sc/iweimhii, but differs in tbe sub- 

 stance, not having any rhubarb tint, and in tbe pileus not being so 

 rough. The South Caroline specimens exactly agree with those from 

 the Himalayas. The name is applicable to the form which wns first 

 described, with a central stem ; in the others the stem is lateral or ob- 

 solete.

Varying considerably in habit, and in the size of the pores. The 

 Nunklow specimens have a very slender stem, and may possibly be 

 distinct, but unfortunately every individual is past its prime, and con- 

 sequently the normal state of the pileus cannot be ascertained.
