Bull. Buff. Soc. 1874, p. 104. Boletus sulphureus Rep. 38, p. 90 
Pileus broadly convex, at first subtomentose, then fascicu 
lately red-pilose, yellowzsh-brown, flesh yellowish-white ; 
tubes at first whztesh, then light-yellow, arcuate-adnate or 
slightly depressed around the stem, the mouths small; stem 
enlarged toward the base, striate at the apex, yellowish or 
pale-cinnamon; spores .o004 in. long, .ooo16 broad. 
Var. aurzcolor. Pileus and subequal stem bright yellow, 
the tomentum of the pileus yellow. 
Pileus 1.5 to 3 in. broad; stem 1 to 2 in. long, 3 to 5 lines 
thick. 
Borders of woods. New England, Frost. New York, 
Peck. 
In the dried state the variety, which occurs in New York, 
cannot be distinguished from the typical form. In drying, 
the margin of the pileus has a tendency to curve upwards. 
The hairy tufts or squamules are very minute and sometimes 
appear almost granular. The species seems intermediate 
between LB. varzegatus and B. sulphureus, with the latter of 
which the variety connects it.
