338 MurrILL: POLYPORACEAE OF NorTH AMERICA 
Specimens are at hand from Massachusetts, banker ; Canada, 
Dearness ; Missouri, Demetrio ; Ohio, James, Lloyd ; West Virginia, 
Nuttall ; Pennsylvania, Everhart; New York, Banker ; Virginia, 
Murrill, ULloyd’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, 1: 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 G7rzfola forms. 
SPECIES INQUIRENDAE 
Polyporus anax Berk. Grevillea, 12: 37. 1883. Described 
from Ohio. Apparently not specificially distinct from G. frondosa. 
Polyporus lactifiuus 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 sistotremoides Alb. & Schw., 
better known as Polyporus Schweinitsii Fr. The plant is a large 
and striking one, quite common in Europe and America, and has
