DOUBTFUL SPECIES 
Boletinus glandulosus Peck, Bull. N. Y. State Mus. 131: 34. 1909. Described from 
specimens collected by Hay in New Brunswick. Probably not distinct from Boletus aeru- 
ginascens Secr. (Mycogr. Suisse 2: 6. 1833), with which B. viscidus Fries (Epicr. Myc. 
423. 1838. Not B. viscidus L. 1753) is synonymous. ‘2. tridentinus Bres. and B. larici- 
nus Berk. are very closely related species, showing the same large, radiating pores. 
Boletus elbensis Peck, Ann. Rep. N. Y. State Cab. 23: 129, 1872. Described from 
North Elba, New York. This species was formerly considered a variety of B. luteus 
having rather large pores. The original specimens appear to have been destroyed, but 
those now at Albany under this name correspond rather closely with Boletinus glandulosus 
Peck. 
7. BOLETELLUS Murrill, Mycologial: 9. 1909. 
Hymenophore anuual, epixylous, centrally stipitate; surface floccose-verrucose, yel- 
lowish: context light-colored, fleshy; tubes angular, depressed, yellowish, covered with 
a veil: spores oblong-ellipsoid, smooth, ferruginous: stipe solid, white, not reticulate.

Boletus Ananas M. A. Curt. Am. Jour. Sci. IT. 6: 351. 1848. 
Boletus tsabellinus Peck, Bull. Torrey Club 24: 146. 1897. (Type from Mississippi.) 
Pileus convex to expanded, somewhat irregular, 5-10 cm. broad; surface light-tan 
with a pinkish tinge to pinkish-brown, covered with a thick coat of conspicuous, imbricate, 
floccose scales, which are reddish flesh-colored fading to almost white; margin thin, 
lacerate, appendiculate : context white or cream-colored, changing to bluish when wounded ; 
tubes plane in mass, adnexed, bright-yellow or tawny-yellow, sometimes with a pinkish 
tinge, becoming greenish-blue when injured, mouths of medium size, angular, edges thin : 
spores ellipsoid, longitudinally striate, dark-brown, 16-18 6-8: stipe 5-10 cm, long, 
1-2 cm. thick, cylindric, even, pure-white or very light-brownish, sometimes tinged with 
pink, changing to duil-red when wounded, solid or slightly hollow within; veil present in 
young stages, but mostly clinging to the margin of the pileus, leaving only a slight trace 
of an annulus in mature specimens. 
TYPE LOCALITY Santee River, South Carolina. 
HaBiTaT: Parasitic on wounded pine trunks or about the base of living pine trees. 
DISTRIBUTION : North Carolina to Alabama and Mississippi. 
8. PULVEROBOLETUS Murrill, Mycologia 1: 9. 1909, , 
Hymenophore annual, terrestrial, centrally stipitate; surface of pileus and stipe 
clothed with a conspicuous sulphur-yellow, powdery tomentum, which may be the remains 
of a universal veil: context white, fleshy; tubes adnate, yellowish, covered with a large 
veil: spores oblong-ellipsoid, ochraceous-brown : stipe solid, annulate, not reticulate. 
Type species, Boletus Ravenelii Berk. & Curt.
