This is a beautiful plant. It is not plentiful, yet it is found frequently on some of our hillsides. The plants in Figure 308 were found in Hayne's Hollow near Chillicothe, and photographed by Dr. Kellerman. The plant is found in New England and through the Middle West. I have had beautiful plants sent me from Vermont. It is not edible, so far as I know. Found in August and September.

The Lurid Boletus.
Figure 309.—Boletus luridus. One-half natural size.
Luridus means pale-yellow, sallow. The pileus is convex, tomentose, brown-olivaceous, then somewhat viscous, sooty. The flesh is yellow, changing to blue when wounded. Tubes free, yellow, becoming greenish, their mouths round, vermilion, becoming orange. The stem is stout, vermilion, somewhat orange at the top, reticulate or punctuate. The spores are greenish-gray, 15×9µ.
The lurid Boletus, though pleasant to the taste, is reputed very poisonous. Boletus rubeolarius, Pers., having a short, bulbous, scarcely reticulated stem, is regarded as a variety of this species. The red-stemmed Boletus, B. erythropus, Pers., is also indicated by Fries as a variety of luridus. It will be seen on the right in Figure 309. It is smaller than B. luridus, has a brown or reddish-brown pileus and a slender cylindrical stem, not reticulated but dotted with squamules. Peck, Boleti of the U. S. The plant is quite abundant in our woods. Found in July and August.
