264 FUNGUS-FLORA. 



yellow, more or less tinged with red, solid, flesh deeper 

 yellow than that of the pileus, usually stained with red; 

 spores elongate- fusiform, pale olive, 12-14 x 4 p. 



Boletus chrysenteron, Fries, Epicrisis, p. 415; Cke., Hdbk., 

 p. 254. 



In woods and pastures. At first continuously covered with 

 a dense olive tomentum, which eventually becomes cracked, 

 the cracks are red. Stem generally crooked, more or less 

 streaked with red. Allied to Boletus subtomentosus, from 

 which the present species is known more especially by the 

 red colour of the flesh below the minutely velvety surface. 



Pileus 2-3 in. or more broad, of various colours, but chiefly 

 some shade of red, olive or yellow, pulvinate, minutely 

 downy ; specimens often cracked in polygons, the interstices 

 reddish ; flesh white or yellowish, changing slightly to blue. 

 Tubes adnate or ascending and then subdecurrent, large, 

 dull yellow, simple, blue when bruised. Stem 3 in. high, 

 i in. thick, nearly smooth, very firm, yellow streaked 

 more or less with red, generally crooked, particularly at the 

 base, which is often suddenly attenuated, though sometimes 

 that part is thickest, changing slightly to blue when cut. 

 (Berk.) 



Var. nanus, Mass. Pileus about 1 in. across, convex, 

 covered with a continuous olive tomentum, which does not 

 crack ; flesh pale yellow, and like that of the stem changing 

 to red when cut ; tubes about 2 lines long, adnate, yellow, 

 eventually with a green tinge, openings elongated, sinuous, 

 narrow ; stem 1 in. long, ^ in. thick, slightly swollen below 

 the centre, firm, yellow, streaked or spotted with crimson 

 below, flesh red at the base from the first ; spores elongato- 

 fusiform, pale olive, 10 x 3 p.. 



Amongst grass under trees. Distinct from the type in the 

 smaller size, in the flesh of pileus and stem becoming red 

 when cut, and in the elongated, narrow, sinuous or gyrose 

 openings of the pores. May possibly prove to be a distinct 

 species. 



Var. versicolor, Host. Pileus about 1^ in. across, nearly 

 plane, minutely velvety, bright deep rose-pink; tubes 

 shorter round the stem, but adnate, ^ in. long, openings 

 large, angular, yellow, greenish when old ; stem 1^ in. long,
