Boletus alboater Scuw. 
BLACK AND WHITE BOLETUS 
Syn. Fung. Car. 864 
Pileus convex, subtomentose-velvety, black; tubes free, 
their mouths rather small, white; stem black. 
Pileus 3 in. broad; stem 2 in. long. 
Moist woods. Frequent. North Carolina and Pennsyl- 
vania, Schweznztz. 
In Epicrisis, p. 424, Fries adds to the description here

some error concerning it. Can it be a black variety of 
Boletus scaber ?
