MURRILL : POLYPORACEAE OF NORTH AMERICA 649 



14. Coriolus planellus nom. nov. 

 Poly porus planus Peck, Rep. N. Y. State Mus. Nat. Hist. 31 : 37. 



1879. Not P. planus Wallr. 1833. 



The type plants of this species were collected on dead branches 

 at North Greenbush, New York. Only a few specimens are at 

 hand : New Hampshire, Blake ; Maine, Murrill ; Iowa, Holway. 



15. Coriolus armenicolor (B. & C.) Pat. 

 Poly porus armenicolor B. & C. Jour. Linn. Soc. Bot. 10 : 315. 



1868. 

 Coriolus armenicolor Pat. Tax. Hymen. 94. 1900. 



Described as follows from Wright's Cuban collections : 



" Pileo tenui subcoriaceo flabelliformi in stipitem spurium attenuato zonato velu- 

 tino interstitiis lineatis ; hymenio alutaceo ; poris minutis, dissepimentis tenuibus den- 

 tatis." 



"On dead wood. Pileus 2^£ inches across, l^ long; pores T ^ inch in diam- 

 eter. The pileus is of a pale tawny or tan-color, with darker lines. Allied to P. 

 versicolor." 



Plants collected by Cockerell in Jamaica in 1890 correspond 

 exactly with Wright's Cuban types at Kew except with respect to 

 the zones of tomentum, which may be variable or evanescent in 

 the species. More material may throw light on this matter. 



16. Coriolus sobrius (B. & C.) 

 Poly porus sobrius B. & C. Jour. Linn. Soc. Bot. 10 : 316. 1868. 

 Described as follows from Wright's collections in Cuba : 



" Pileo imbricato flabelliformi opaco glaberrimo subzonato tenui umbrino-cinereo 

 nebuloso ; poris parvis laceratis." 



"On dead wood. Pileus § inch wide, § inch long ; pores fa inch in diameter. 

 Somewhat resembling P. sector, var. zonarius, but, I think, distinct." 



The small thin purplish zonate type plants now at Kew appear 

 quite distinct. 



17. Coriolus nigromarginatus (Schw.) 

 Boletus hirsutus Wulf. in Jacq. Collect. 2: 149. 1788. Not 



Boletus hirsutus Scop. Fl. Cam. ed. 2. 2 : 468. 1772. 

 Boletus nigromarginatus Schw. Syn. Fung. Car. 72. 1818. 

 Poly poms hirsutus Fr. Syst. Myc. 1 : 367. 1821. 



Originally described from plants collected in Carinthia, where 

 Wulfen found it very common on tree trunks in the forests and
