A good illustration of this I found in the case of Boletus edulis during my stay in the North Carolina mountains. The plant usually occurs singly and more or less scattered. I found one case where there were 6–8 plants in a tuft, the caps were smaller and the stems in this case considerably longer than in normal specimens. A plant which agrees with the North Carolina specimens I have collected at Ithaca, and so I judge that B. retipes occurs in New York.
Boletus chromapes Frost.—This is a pretty boletus, and has been reported from New England and from New York State. During the summer of 1899 it was quite common in the Blue Ridge mountains, North Carolina. The plant grows on the ground in woods. It is 6–10 cm. high, the cap is 5–10 cm. in diameter, and the stem is 8–12 mm. in thickness. It is known by the yellowish stem covered with reddish glandular dots.

The pileus is convex to nearly expanded, pale red, rose pink to vinaceous pink in color, and sometimes slightly tomentose. The flesh is white, and does not change when cut or bruised. The tube surface is convex, and the tubes are attached slightly to the stem, or free. They are white, then flesh color, and in age become brown. The stem is even, or it tapers slightly upward, straight or ascending, whitish or yellow above, or below, sometimes yellowish the entire length. The flesh is also yellowish, especially at the base. The entire surface is marked with reddish or pinkish dots.
