60 NORTHERN POLYPORES 



SUPPLEMENTARY NOTES 



Tyromyces (Polyporus) caesiosimulans Atk. Jour. Myc. 6: 61. 1908. Said to 

 be near T. caesius (Schrad.) Murrill, but to have globose, pedicellate spores. 



Polyporus confluens (Alb. & Schw.) Fries. Reported more than once from 

 America. 



Microporellus dealbalus (Berk. & Curt.) Murrill. Occasional southward in the 

 Mississippi valley. 



Polyporus epileucus Fries. Reported from South Carolina by Curtis and said 

 by others to occur northward. 



Tyromyces (Polyporus) fumidiceps Atk. Ann. Myc. 6: 61. 1908. Said to be 

 near T. chioneus (Fries) Karst., but to have a darker pileus and very different 



Trametes merisma Peck, Bull N. Y. State Mus. 139: 31. 1910. Pendant from 

 the lower surface of dead prostrate beech trunks. 



Polyporus osseus Kalchb. Occasional northward. 



Polyporus pennsylvanicus Sumstine, Jour. Myc. 13: 137. 1907. Recently re- 

 ported also from Ohio and said to be near P. caudicinus (Scop.) Murrill, but 

 worthy of distinct rank. 



Scutiger retipes (Undenv.) Murrill. Reported from New Jersey. 



Coriolus sericeohirsutus (KI.) Murrill. Occasional southward. 



Polyporus spumeus (Sow.) Fries. Recently reported from Ohio as being very 

 near Spongipellis deletions (Peck) Murrill, but having smaller tubes and more 

 globose spores. Some consider it the same as S. galactinus. 



Tyromyces (Polyporus) subpendulus Atk. Jour. Myc. 6: 61. 1908. Similar to 

 Porodisculus pendulus in form but very different in structure and occurring on 

 Tsuga. 



Cryptoporus volvatus (Peck) Hubbard. This species is so distinct as to consti- 

 tute a new tribe, the Volvatae, characterized by the presence of a volva. The 

 sporophore is annual and matures early in the season, so that the volva would 

 probably rupture by decay in time to distribute the spores even if no apertures 

 were present.
