SCUTIGER RADICATUS (Schw.) Mumll 



See " Western Polypores " for a descriptive account of Scutiger 

 hispidellus (Peck) Murrill, which is distinct from Scutiger radi- 

 catus. It is claimed that P. Kansensis is also distinct, on the 

 ground that it is different in habit and also has different spores. 



Scutiger persicinus (Berk. & Curt.) Murrill 



Compare " Southern Polypores " for notes on a recent collec- 

 tion of this species. 



Scutiger Whiteae Murrill 



This is the representative of Polyporus confluens (Alb. & 

 Schw.) Fries in America. It is pale-colored when fresh, re- 

 sembling P. ovinus, but turns reddish instead of gray in the her- 

 barium. I have it from Tolland, Colorado; Banff, Canada; and 

 Hague, New York; as well as from Maine. 



Grifola poripes (Fries) Murrill 



Change to Grifola cristata (Schaeff.) S. F. Gray. Several col- 

 lections received from Europe show that the American plant is 

 not distinct. It was first described and figured by Schaeffer 

 (Fung. Bavar. Ind. 81. pi. 113. 1774) under the name of Boletus 

 flabetliformis, which he later changed to Boletus cristatus (Fung. 

 Bavar. Ind. 93. pi. 316, 317. 1774). Boletus flabelliformis was 

 used by Scopoli in 1770 for a different plant. 



Grifola Sumstinei Murrill 



Change to Grifola mesenterica (Schaeff.) Murrill. Originally 

 described as Boletus mesentericus by Schaeffer (Fung. Bavar. 

 Ind. 91. pi. 267. 1774) and renamed Boletus giganteus by Per- 

 soon. 



Grifola frondosa (Dicks.) S. F. Gray 



Some claim that Polyporus intybaceus is distinct. Practically 

 all the specimens so labeled, however, afe G. frondosa.
