MURRILL : POLYPORES OF TEMPERATE NORTH AMERICA 7 



Hydnoporia fuscescens (Schw.) Murrill 



Change to Hydnochaete olivacea (Schw.) Banker, as published 

 in Mycologia 6 : 234. 1914. This species remains in the Poly- 

 poraceae. 



FOMITIPORIA DRYOPHILA Murrill 



Probably not distinct from Pyropolyporus Calkinsii Murrill. 



Coriolus hirsutulus (Schw.) Murrill. 

 Only a form of Coriolus versicolor (L.) Quel. 



Coriolus pubescens (Schum.) Murrill 

 Add to synonymy P. Grayii Cooke. 



Coriolus balsameus (Peck) Murrill 



This species has been recombined as Tyromyces balsameus 

 (Peck) Murrill. 



Coriolus Lloydii Murrill 



This may be only a form of the variable Coriolus pubescens 

 (Schum.) Murrill. 



Coriolus pinsitus (Fries) Pat. 



Add to synonymy Boletus villosus Sw. Prodr. 148. 1788. Not 

 B. villosus Huds. 



Coriolus biformis Murrill 



Polyporus biformis Klotzsch having been wrongly interpreted. 

 Coriolus molliusculus (Berk.) Murrill was adopted in "Northern 

 Polypores " for this species. According to Bresadola, who has 

 sent me excellent specimens to support his opinion, Trametes 

 populina (Schulz.) Bres. is not distinct from C. molliusculus. If 

 true, then his name would have priority unless the doubtful 

 Boletus cervinus Schw. could be shown to be the same thing. 



Coriolus prolificans (Fries) Murrill 



Change to Coriolus biformis (Klotzsch) Pat. (Polyporus bifor- 

 mis Klotzsch, Linnaea 8: 486. 1833).
