338 Murrill : Polyporaceae of North America 



Specimens are at hand from Massachusetts, Banker ; Canada, 

 Dearncss ; Missouri, Demetrio ; Ohio, James, Lloyd ; West Virginia, 

 Nuttall ; Pennsylvania, Everhart ; New York, Banker ; Virginia, 

 Murrill. Lloyd's photogravures 23 and 24 exhibit the appear- 

 ance and habit of the living plant most accurately and beautifully. 

 It seems fitting that this magnificent plant should be so well rep- 

 resented. It is also appropriate that it should bear the name of a 

 man who has done so much for American mycology. 



6. Grifola fractipes (B. & C.) 



Polyporus fractipes B. & C. Grevillea, I : 38. 1872. 



Little is known of this species beyond the collections of Curtis 

 and Ravenel in South Carolina and an occasional plant reported 

 from adjoining states. The specimens at hand are better devel- 

 oped than those at Kew, with older and larger pores, and show a 

 close relationship rather with species of Grifola than Polyporus. 

 Although the stipe is not branched in these specimens, it is dis- 

 torted and tubercular at the base as though united with other 

 pilei that were as yet immature. So far as the general structure 

 of context and hymenium goes the species exhibits very close sim- 

 ilarity with typical Grifola forms. 



Species inquirendae 



Polyporus anax Berk. Grevillea, 12: 37. 1883. Described 

 from Ohio. Apparently not specificially distinct from G. frondosa. 



Polyporus lactifuus Peck, Bull. Torrey Club, 8: 51. 1881. 

 Described from dried material and notes sent by Miss Banning 

 from Maryland. It seems different from G. Berkeleyi only in hav- 

 ing milky juice, a character possessed by other members of this 

 genus and probably present in G. Berkeleyi in its young stages. 



Romellia gen. nov. 



Hymenophore large, irregular, annual, spongy to corky, epixy- 

 lous ; stipe simple, variously attached, surface of pileus anoderm, 

 hispid ; context ferruginous, tubes irregular, thin-walled, spores 

 ellipsoidal, smooth, hyaline, cystidia none. 



The type of this genus is Boletus sistotrcmoides Alb. & Schw., 

 better known as Polyporus Schweinitzii Fr. The plant is a large 

 and striking one, quite common in Europe and America, and has
