"286 FUNGUS-FLORA. 



"base and tinged with red higher up. Taste extremely bitter 

 like gall. 



A fine figure of the above, which may prove to be distinct, 

 is in the British Museum collection of drawings of fungi. 



Boletus regius. Kromb. 



Pileus 3-5 in. across, very convex, almost hemispherical, 

 minutely tomentose, bright rose-pink ; flesh very thick, pale 

 yellow, unchangeable ; tubes ^ f in. long, much depressed 

 round the stem, golden-yellow, openings subangular, about 

 ^ mm. across; stem 2-31 in. long, 1 in. thick, subequal, 

 solid, pale yellow except the base, which is dingy purple, 

 vaguely reticulated or with minute squamules ; spores 

 elongate-fusiform, pale yellow, 16 x 5 p- 



Boletus regius, Krombholtz, t. 7 ; Fries, Hym. Eur., 

 p, 508. 



On the ground in open places, &c. A very beautiful 

 species, either solitary or in small clusters. The British 

 specimens differ from Fries' description, which says that the 

 pileus is glabrous and the tubes short, but this description 

 is drawn up from Krombholtz's figure. 



Boletus crassus. Mass. (n. sp.) 



Pileus 35 in. across, convex then expanded, often ir- 

 regularly waved or nodulose, densely tomentose, tomentum 

 collected in little fascicles, sometimes cracked in an areolate 

 manner, flesh thick up to the margin, ^-f in. or more, firm, 

 for a long time white, then pale primrose-yellow, colour of 

 pileus rather pale yellow- brown ; tubes short at first, 

 eventually |-f in. long, shortened round the stem and 

 nearly or quite free, openings irregularly rounded, generally 

 simple, about ^ mm. across, for a long time white, then bright 

 but pale primrose-yellow; stem at first almost globose, at 

 length becoming a little elongated, about 2 in. long, and 

 nearly as thick, slightly attenuated at the apex, a little 

 paler than the pileus above, becoming almost white towards 

 the base, glabrous, upper portion with conspicuous raised 

 white lines arranged to form a more or less regular polygonal 

 network, solid ; flesh white when young, becoming ?pale 

 yellow with age ; spores elliptic-fusiform, pale yellow,
