Woods. Sandlake. August. 
This species is rare with us. It is remarkable for its long lacunose-

and sometimes strongly curved at the base. Mr. Frost finds a form 
with the stem much twisted.

If I understand this species correctly it often attains much larger 
dimensions than those given in the description. The tubes are at 
first whitish but in drying they change to a brown color. They 
become dingy-brown where bruised. The stem sometimes tapers

yellow veil. The pileus is reddish where the pulverulence has van- 
ished. The plant is sometimes ceespitose. 
BoLEtus NIGRELLUS 7. sp. 
Pileus dry, minutely tomentulose, blackish; tubes plane or convex, 
scarcely depressed around the stem, small, unequal, subrotund, whitish, 
then tinged with pink ; stem equal, short, even, colored like the pileus ;
