 (Type from Port Jefferson, New York.) 



This widespread species, of general distribution in deciduous 

 woods throughout Europe and temperate North America, has 

 many varieties and has been assigned many names, a number of 

 which do not appear in the above synonymy. As in certain other 

 species of boleti, the stem may be either entirely even or more or 

 less reticulated, which has led to confusion. Boletus illudens, for 

 example, is a variety with coarse reticulations which has received 

 several names in Europe. This species is of a spongy texture 

 and may be dried in the sun. The cap is usually yellowish-brown 

 or olive-tinted, with a distinct tomentum, and the large tubes and 

 stem are yellow. C. communis, a closely related species, usually 

 has more red both in cap and stem. 



32. Ceriomyces tomentipes (Earle) 



Boletus tomentipes Earle, Bull. N. Y. Bot. Gard. 3 : 298. 1905. 



This species suggests a gigantic C. communis. The tomentum 

 on the cap and stem are peculiar, as is also the change in color of 

 the tubes from yellow to brick-red. Described from specimens- 

 collected by C. F. Baker at Stanford University, California. 



33. Ceriomyces fumosipes (Peck) 



Boletus fumosipes Peck, Ann. Rep. N. Y. State Mus. 50: 108.. 

 1898. 



Described from Port Jefferson, New York, from specimens col- 

 lected by Peck in woods during July. It has since been found 

 abundantly in the mountains of North Carolina both by Atkinson 

 and myself, and I have also collected it at Falls Church, Virginia.. 

 The species is peculiar in having a pale bluish-green band at the 

 top of the stipe. The cap is very reticulate-rimose, and the tubes 

 are grayish-white, afterwards discolored by the deep ochraceous- 

 brown spores.
