44 MURRILL : POLYPORACEAE OF NORTH AMERICA 



is a caespitose species with slender pruinose stipe, small pellucid 

 pileus, ciliate margin and very minute polygonal or sinuose tubes. 

 Saccardo considers it the same as P. fiexipes Fr. and P. liapalus 

 Berk., but these two species do not, so far as I know, occur in the 

 West Indies or even in Central America. 



Polyponis Hiimplireyi P. Henn. Hedwigia, 37 : 280. 1 898. 

 From the description of this species it appears to resemble P. Tri- 

 choloma, but has adnate instead of decurrent tubes with whitish 

 fimbriatulate edges. This and the next species are placed here 

 because I have not yet examined the type specimens.

 1902. This species is found in Guadeloupe and Martinique and 

 is related to Favolus inelanopus. It is deeply umbilicate, ochra- 

 ceous, with translucent denticulate margin, which is sterile below, 

 large shallow radiating tubes and a black central stipe. Undevel- 

 oped plants resemble certain species of Xylaria. An examination 

 of the plant is necessary to determine whether or not it properly 

 belongs with Polyponis.
