Figure 301.—Boletus retipes. Natural size.
Retipes is from rete, a net; pes, a foot; so called from the delicate net-work seen on the stem.
The pileus is convex, dry, powdered with yellow, sometimes rivulose or cracked in areas. The tubes are adnate, yellow.
The stem is subequal, cespitose, reticulate to the base, pulverulent below. The spores are greenish-ochraceous, 12–15×4–5µ. Peck, Boleti.
B. retipes is very close to B. ornatipes, but its manner of growth, its pulverulent cap, and its greenish-ochraceous spores will at once distinguish it. I have found them on Ralston's Run, a number from the same mycelial cluster, as in Figure 301. The caps only are good. The specimens in the figure were found near Ashville, N. C., and photographed by Prof. H. C. Beardslee.
