Mycologia 



specimens have recently been collected in North Carolina by Dr. 

 House, Miss Burlingham and myself. The description given by 

 Berkeley is both incomplete and inaccurate, but the bright golden- 

 yellow color of the pileus and stem should easily distinguish it. 

 The mouths of a few of the tubes sometimes appear scarlet, espe- 

 cially on drying, but this character is not at all conspicuous. The 

 stem is beautifully reticulated. 



13. Ceriomyces parasiticus (Bull.) 



Boletus parasiticus Bull. Herb. Fr. pi. 451. f. 1. 1789. 

 Versipellis parasitica Quel. Ench. Fung. 159. 1886. 

 Xerocomus parasiticus Quel. Fl. Myc. 418. 1888. 



Distinct from all other boleti in being parasitic. If separated 

 from the Scleroderma on which it grows, it might be confused 

 with C. subtomentosus. It has been found in several places in 

 New York and New England, as well as in Europe and Asia. 



14. Ceriomyces hemichrysus (Berk. & Curt.) 



Boletus hemichrysus Berk. & Curt. Ann. Mag. Nat. Hist. II. 12 : 

 429. 1853. Grevillea 1 : 35. 1872. 



This very rare species was described from specimens collected 

 by Ravenel in South Carolina on roots of Pinus palustris. It has 

 since been collected in North Carolina, Alabama, New Jersey and 

 New York, and always on roots or stumps of some species of 

 pine. It is just possible that this is the plant found by Mcllvaine 

 in clusters on old stumps near Philadelphia and described by Peck 

 as Boletus fulvus. 



15. Ceriomyces eximius (Peck) 



Boletus robustus Frost, Bull. Buffalo Soc. Nat. Hist. 2 : 104. 



1874. Not Boletus robustus Fries. 185 1. 

 Boletus eximius Peck, Jour. Mycol. 3 : 54. 1887. 



Described from Brattleboro, Vermont, and found in thin woods 

 and along roadsides from Nova Scotia to North Carolina and 

 west to Pennsylvania and West Virginia. Its stem is very char- 

 acteristic, being lilac-gray and furfuraceous, while the cap and 

 tubes are chocolate-brown.
