268 FUNGUS-FLOKA. 



Pileus 2-5 in. across, convex then expanded, smooth, even 

 blood-red with a tinge of purple in some of the younger 

 specimens ; tubes ^ in. or more long, adnate, plane, openings 

 large, pale olive-green when mature; stem 3-4^ in. long, 

 V in. or more thick, equal, yellow, more or less streaked 

 with red, especially upwards, flesh, like that of the pileus, 

 yellowish. 



As already stated, this is considered by Sowerby to be 

 Boletus communis, Bulliard, t. 393, but the latter is quoted by 

 Fries under Boletus subtomentosus, and the figure certainly 

 appears to agree with the last-named species, and has not a 

 trace of red about the pileus, hence it appears certain that 

 Sowerby was wrong in referring his plant to Bulliard's B. 

 communis ( = B. subtomentosus), and as it does not agree in habit 

 and other particulars with B. chrysenteron, it may be considered 

 as a distinct species, but until, like Withering's species, it is 

 met with again, it had better remain as it is, now that 

 attention has been called to the matter. The curse of 

 establishing species from figures presses already heavily 

 enough on the systematist without adding to the load. 



In Cooke's Handbook and Stevenson's British Fungi, 

 Fries' description of Boletus sanguineus is copied without 

 comment. 



Boletus impolitus. Fries. 



Pileus 46 in. across, convex, then more or less expanded, 

 flocculose, at length granuloso- rivulose, not polished, rather 

 pale yellow-brown, flesh thick, pale yellow below the 

 cuticle; tubes nearly free, ^ J in. long, openings minure, 

 yellow ; stem 23 in. long, 1^52 in. thick at the base, some- 

 what bulbous or inflated below, yellow, even, pubescent, 

 sometimes tinged with red near the apex; spores pale olive, 

 elongato-fusiform, 1415 x 5 //..

 Svamp., t. 42. 



In woods. 



A large fine species, pileus yellow-brown or tawnv- 

 brown, tomentose, sometimes cracking into areolae. Stain 

 yellow, tomentose, not reticulated. Attains a diameter 

 of 4 in. or more ; stem about 2 in. Flesh more or less 

 changing to blue when cut. Often very large. (Cooke.)
