Boletus biennis, Sow., t. 191. 



On stumps, &c. Distinguished amongst the hairy, soft- 

 fleshed species by the whitish-pink hymenium, and the large, 

 sinuous, torn pores that are often 1 mm. wide, and 2-4 mm. 

 long. 



Habit of growth resembling that of Polyporus Sehweinitzii, 

 but it is smaller, softer, and different in colour both exter- 

 ■ mally and internally. (Fries.) 



The stipes (occasionally central and covered with naked 

 pores) is somewhat tomentose. Pores varying into sinuses 

 and labyrinths very irregularly. The pileus is rather hispid. 

 It hardens in drying, becoming woody. (Sow.) 



In the two specimens figured by Sowerby, the stem is in 

 both instances distinctly lateral, about 1^ in. long, pileus 

 pale brown, pores pale pink. 



Pileus convex when young, at length plane or even de- 

 pressed, velvety or hispid, 1-3 in. broad, irregular, furnished 

 underneath with large, irregular, very flexuous or labyrinth- 

 , like pores, greyish or flesh-coloured. Stipes when present 

 very irregular, unequal, even grotesque, 1-2 in. high, of 

 various thickness, ferruginous, sometimes wanting, when the 

 c pileus becomes dimidiate, as growing from the side of a rotten 

 post; in this situation it is even sometimes imbricated. 

 When dry it is hard and woody. (Grev.)
