DOUBTFUL SPECIES 
Boletus badiceps Peck, Bull. Torrey Club 27: 18. 1900. Described from notes and 
drawings made by McIlvaine from specimens collected in oak woods near Philadelphia, 
Pennsylvania. ‘Types destroyed. 
Boletus Bakert Tracy & Earle, Pl. Baker. 1: 23. 1901. Described from specimens 
collected in moist aspen thickets in Colorado, at an elevation of nearly 3000 meters. ‘Too 
near C. crassus to be recognized as distinct without the discovery of better characters. 
Boletus cubensis Berk. & Curt. Jour. Linn. Soc. 10: 304. 1868. Known only from 
plants collected on the ground in Cuba by Wright. The types at Kew are pressed flat and 
show little except the squamulose, spotted character of the surface and the copious spores, 
which are oblong-ellipsoid, smooth, yellowish-brown, 17-217. This species seems very 
near to C. guadelupensis, and C. communis is with difficulty distinguished from either, 
except by its smaller spores. A Ceriomyces cubensis has already been published by Patouil- 
lard for a plant in a different group of fungi. 
Boletus dictyocephalus Peck, Bull. N. Y. State Mus. 8: 111. 1889. Described from 
notes and a single specimen collected by C. J. Curtis in North Carolina. Type not found. 
Boletus eccentricus Peck, Bull. Torrey Club 27: 18. 1900. Described from notes and 
drawings made by McIlvaine from specimens collected in grassy places in woods at Mt. 
Gretna, Pennsylvania. Types destroyed. 
Boletus fuluus Peck, Bull. Torrey Club 27: 19. 1900. Not Boletus Julvus Scop. De- 
scribed from notes and drawings made by McIlvaine from twenty to thirty specimens col- 
lected on-and about an old stump near Philadelphia, Pennsylvania. Types destroyed. 
Boletus ignoratus Banning ; Peck, Ann. Rep. N. Y. State Mus. 44: 185. 1891.
