This species is admitted on the authority of Mr. Frost who alone has recorded it in this country. But specimens received from him under this name do not in my opinion belong to it, and its occurrence here is somewhat doubtful. Peck, Boleti of the U.S.
In oak woods near Bartram’s Garden, West Philadelphia, in 1887–1888, I found several Boleti answering the description, exactly, of B. spadiceus. They proved to be good eating.
