Maine, by Miss V. S. White, No. 148, and deposited in the 
herbarium of the New York Botanical Garden. The species is 
found distributed more or less sparingly from IVIaine to Alabama. 
The following specimens appear to belong here: Maine, White; 
New Jersey, Ellis; Maryland, Shear; Alabama, Earle. The spe- 
cies is also represented by many of the specimens in the following 
exsiccati under the name Hydniim ferrugineiim Fries: Ellis, N. 
Am. Fung. 928; and Shear, Ell. and Everh. Fung. Columb. Cont. 
1409 - 
In our previous papef, loc. cit., we identified our American 
plants with Secretan’s species solely on the basis of his descrip- 
tion. The type of H. carbunculus Seer, has not been located 
and probably is not in existence. No specimens were found in 
European herbaria referred to his species, and it seems probable 
that the name is not there recognized as anything more than a 
synonym of H. ferrugineiim Fries Secretan himself evidently re- 
garded his species as the same as H. ferrugineiim Fries and pro- 
posed the name on the ground that Fries’s name was preoccupied 
by H. ferrugineiim Pers. His description, however, does not 
accord well with authentic specimens of the Friesian species, but 
does apply well to our American plants. 
On the other hand, our plants appear to be entirely distinct 
from any European forms, as but one doubtful specimen was 
found in Europe that seemed to show any affinity'with the Amer- 
ican species. That was a specimen at Upsala received from 
Karsten and referred to H. ferrugineiim Fries but was evidently 
cjuite different from authentic specimens of that species in the 
same herbarium. It was not, however, any nearer to our Amer- 
ican forms. A specimen from Bresadola in the New York 
Botanical Garden Herbarium and referred by him to H. ferriigin- 
eiim Fries also somewhat approaches in appearance the xA.merican 
plants but is clearly not the same. 
Although Secretan’s description is admirably adapted to our 
American forms, it seems l>est to treat the American segregation 
as a distinct species for which we now propose a specific name.’ 
Our grounds for this decision are: first, the fact that both by 
himself as well as by other European mycologists Secretan’s spe- 
cies was regarded as equivalent to H. ferrugineiim Fries; second.
