MURRILL I BOLETACEAE OF NORTH AMERICA 



2. Boletinus grisellus Peck, Mem. N. Y. State Mus. 3 : 

 169. pi 52. /. 1 3-1 p. 1900 



This rare species was described from specimens collected by 

 Morris at Natick, Ellis, and Waltham, Massachusetts. It grows 

 under or near tamarack trees, and develops late in the season. 



3. Boletinus Berkeleyi nom. nov. 

 Boletus decipiens B. & C. Ann. Mag. Nat. Hist. II. 12 : 430. 



1853. Not Boletus decipiens Schrad. 1794. 

 Boletinus decipiens Peck, Bull. N. Y. State Mus. 2 : 78. 1889. 



This species occurs in thin woods along the Atlantic seaboard 

 from New Jersey to Florida. The central stem and much 

 broader, ochraceous-ferruginous spores distinguish it from B. 

 merulioides in dried plants where the veil may be inconspicuous. 



4. Boletinus appendiculatus Peck, Bull. Torrey Club 23 : 



418. 1896 



Only a single pileus remains of the type specimen collected by 

 Yeomans under fir trees in Washington, D. C. Peck's descrip- 

 tion is as follows : 



" Pileus fleshy, convex, glabrous, ochraceous-yellow, the mar- 

 gin appendiculate with an incurved membranous veil, flesh pale- 

 yellow, unchangeable ; tubes rather small, yellow, their mouths 

 angular, unequal, becoming darker or brownish where wounded ; 

 stem solid, slightly thickened at the base, yellow; spores pale- 

 yellow, oblong, .0004 to .0005 in. long, about .00016 broad ; pileus 

 4 to 8 in. broad; stem 2 to 3 in. long, 4 to 6 lines thick." 



5. Boletinus spectabilis Peck, Ann. Rep. N. Y. State 



Mus. 23 : 128. pi 6. f. 1-3. 1872 



This showy species occurs sparingly in exposed northern 

 swamps in Canada and the northern United States from New 

 England and New York to Wisconsin. The pileus is adorned 

 with conspicuous red scales; the flesh and tubes are yellow, the 

 latter soon colored darker by the purplish-brown spores.
