BOLETUS. 265 



^ in. thick, apex yellowish, rest more or less red, solid. ; spores 

 pale yellow, fusiform, 10 X 3 /j,. 



Boletus versicolor, Eoskovius, in Sturm's Deutschl. FL, 

 t. 10; ; Fries, Hym. Eur., p. 504. 



In woods. Distinguished by the clear rose-pink tomen- 

 tose pileus. Although Fries accepts the above as a species, 

 he says that he has seen a variety of B. chrysenteron exactly 

 similar, and considers that it may be a variety of the last- 

 named species. 



Boletus striaepes. Seer. 



Pileus convex then expanded, soft, silky, olive, ferruginous 

 under the cuticle ; tubes adnate, angular, greenish, pores 

 minute, yellow; stem firm, curved, yellow, with blackish- 

 brown striations, base reddish-brown. 



Boletus striaepes, Seoretan, Fl. Mycol. Suis., n. 32 ; Fries, 

 Hym. Eur., p. 502 ; Berk., Outl., p. 232. 



In pine woods. A species respecting which but little is 

 known in this country. Appears to be near Boletus chrysen- 

 teron. 



Boletus subtomentosus. Linn. 



Pileus 2-4 in. across, convex then expanded, soft, dry, 

 velvety, dingy olive, dark umber-brown with olive tinge, or 

 yellowish-brown, often cracked in an areolate manner, the 

 interstices yellowish, no tinge of red under the cuticle ; 

 tubes adnate, ^ in. long, openings angular, §-1 mm. across, 

 yellow; stem 2-3 in. long, |- in. thick, attenuated at the 

 base, often slightly ventricose, more or less ribbed, yellowish, 

 usually streaked with red, solid ; spores elongato-elliptical , 

 pale brownish-olive, 13-14 X 5 /«.. 



Boletus subtomentosus, Linn., Suec, n. 1251 ; Fries, Hym. 

 Eur., p. 503; Bulliard, t. 393; Stev., Brit. Fung., p. 172. 



In woods. Eesembling Boletus chrysenteron in size, habit, 

 and general appearance, but known by the absence of a red 

 tinge under the tomentum of the pileus. The stem is 

 slightly rough with minute points. Young specimens of 

 B. chrysenteron lasLj be mistaken for the present species, 

 unless a section of the pileus is made, when the red colour 

 of the flesh below the cuticle decides the point. Berkeley 

 says that the present species often grows on beech-nuts.
