Murrill: Boletaceae of North America 151 



21. Ceriomyces tabacinus (Peck) 



Boletus tabacinus Peck, Bull. Torrey Club 23: 418. 1896. 



Known only from specimens collected in clay along roadsides 

 in Alabama. Its tawny-brown cap and stem, the latter reticu- 

 lated, and its peculiar habitat should distinguish the species. 



22. Ceriomyces retipes (Berk. & Curt.) 



Boletus retipes Berk. & Curt. Grevillea 1 : 36. 1872. 



Boletus ornatipes Peck, Ann. Rep. N. Y. State Mus. 29 : 67. 



1878. (Type from North Elba, New York.) 



An attractive and well-marked species occurring commonly in 

 thin woods from Nova Scotia to Alabama and west to Wisconsin. 

 The cap varies in color from yellow to brown, the flesh and tubes 

 are yellow, and the yellow stem is beautifully reticulated to the 

 base. It was first described by Berkeley from plants collected by 

 Curtis in North Carolina. Peck referred his first collections in 

 New York to this species in 1872, but afterwards separated them 

 under the name B. ornatipes. 



23. Ceriomyces speciosus (Frost) 

 Boletus speciosus Frost, Bull. Buffalo Soc. Nat. Hist. 2: 101. 



1874. 



Described from Brattleboro, Vermont, and found in thin decid- 

 uous woods from New England to North Carolina and Tennessee. 

 It is a beautiful species, known by its apple-red cap, without 

 bloom, and its brilliant yellow tubes and stem, the latter reticu- 

 lated. C. bicolor and C. Peckii are closely related species. 



24. Ceriomyces Peckii (Frost) 



Boletus Peckii Frost, Peck, Ann. Rep. N. Y. State Mus. 29 : 45. 

 1878. 



Boletus roseotinctus Peck, Bull. Torrey Club 27: 612. 1900. 

 (Type from North Carolina.) 



This species occurs in rather open deciduous woods, especially 

 along roads, and has been found from New England to North 

 Carolina and west to Indiana. It was first described from speci-
