Murrill: Boletaceae of North America 147 



cap is small, subconical, ornamented with conspicuous dark purple 

 scales ; the tubes are salmon-colored near the margin, becoming 

 incarnate as the spores mature. On seeing the types of C. coni- 

 cus, I realized at once that it was closely related to the present 

 species, but Dr. Farlow has assured me, after a careful micro- 

 scopic examination, that the difference in the size of the spores 

 is alone sufficient to distinguish the species, those of C. conicus 

 being considerably longer and about twice as broad. 



10. Ceriomyces flaviporus (Earle) 



Boletus flaviporus Earle, Bull. N. Y. Bot. Gard. 3 : 297. 1905. 



Described from specimens collected by C. F. Baker at Stanford 

 University, California. It differs from C. auriporus in being 

 much larger, and in having larger spores. The general appear- 

 ance of the two species is very similar. 



11. Ceriomyces auriporus (Peck) 



Boletus auriporus Peck, Ann. Rep. N. Y. State Mus. 23: 133. 

 1872. 



Boletus innixus Frost, Bull. Buffalo Soc. Nat. Hist. 2 : 103. 



1874. (Type from Vermont.) 

 Boletus caespitosus Peck, Bull. Torrey Club 27:17. 1900. ( Type 



from Virginia.) 



This very attractive species, the tubes of which retain their 

 golden-yellow color on drying, was originally described from 

 North Elba, New York. It occurs in thin dry woods and on 

 shaded roadsides throughout the eastern United States, from New 

 England to Alabama. The cap is usually reddish-brown and the 

 stem is viscid if the weather is not too dry. 



12. Ceriomyces auriflammeus (Berk. &Curt.) 



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



This species is of great interest, being very rare and very beau- 

 tiful. It was originally collected in North Carolina by Rev. M. 

 A. Curtis and sent by him to Berkeley, who described it. Peck 

 found one plant at Sandlake, New York, and it was also reported 

 by Beardslee from Brookside, West Virginia. A number of fine
