APPENDIX (Boletus).
The descriptions of the following species are scarcely sufficient to permit of the satisfactory reference of the species to their places in the tribes. It is to be hoped that these plants may again be found and their proper relations be ascertained.
B. Ana´nas Curt. Pileus pulvinate, thickly and rigidly floccose-verrucose, yellow, flocci white above, flesh-colored beneath, the margin thin, membranous, lacerated; hymenium plane, depressed around the stem, yellow or tawny-yellow, becoming greenish where wounded, their mouths medium size, obtusely angular. Stem even, solid, somewhat enlarged at the base, white. Spores ferruginous.
Pileus 3–4 in. broad. Stem 3–4 in. long, 6–9 lines thick.
Under prostrate trunks of pine trees.
South Carolina, Ravenel; North Carolina, Curtis.
This is said to approach S. strobilaceus in habitat, but to be otherwise very different. It is placed among the Subtomentosi in Sylloge, but from these it recedes by its floccose wart-like scales. Peck, Boleti of the U.S.
B. radico´sus Bundy. Pileus thin, wide, recurved, yellow tinged with brown, the cuticle easily removed. Flesh pale-yellowish tinged with pink, not changing color when bruised. Tubes decurrent, large, uneven-mouthed, compound, angular, tinged with brown. Stem flexuous, yellow above, whitish below, rough with dark appressed scales, fibrous-rooted.
Pileus 4 in. broad. Stem 3–4 in. long, 5 lines thick.
