280 FUNGUS-FLORA. 



attenuated, smooth, rather paler than the pileus, without a 

 ring, solid, flesh with a tinge of brown ; spores elongato- 

 fusiform, olive, 16 X 4 /x. 



Gregarious, but not caespitose. Amongst sphagnum in a 

 swamp. Without any very near ally, probably nearest to 

 slender forms of Boletus hadius, from which it is at once dis- 

 tinguished by the very thin flesh of the pileus, brighter 

 colour, long slender stem, short tubes, &o. 



Boletus bovinus. Linn. 



Fasciculate. Pileus 2-3J. in. across, convex then almost 

 plane, margin acute, pale reddish -yellow, glabrous, viscid, 

 shining when dry, with traces of the gluten remaining as 

 fibrils or ridges, flesh rather thin, whitish, unchangeable ; 

 tubes subdecurrent, up to ^ ia. deep, openings compound, sub- 

 angular, often elongated radially, ^-1^ mm. across, dingy 

 yellow, then brownish-oinnamon ; stem 2-4 in. long, ^ in. 

 or more thick, equal, even, coloured like pileus, apex often

Boletus hovinus, Linn., Suec, n. 1246 ; Fries, S. M. i. p. 

 388 ; Cke., Hdbk., p. 252. 



Heathy fir woods, &c. Pileus rather thin for a Boletus, 

 stem thin usually elongated, clustered or gregarious. 



G-regarious, fasciculate ; pileus 1-2J in. broad, when young 

 hemispherical, margin white and tomentose, disc and top of 

 stem purplish, base rhubarb-coloured; when full-grown 

 convex, expanded, margin still turned in, very glutinous, 

 dull orange-yellow, or deep buff; flesh tinged with the colour 

 of the pileus, not changeable. Tubes resembling the pores of 

 Merulius lachrymans, very shallow (J in.), compound, dirty 

 yellow, not easily separating from the pileus. Stem 2-3 in. 

 high, ^— f in. thick, subtomentose, not diffused gradually but 

 rather abruptly into the pileus, of the same colour, but 

 streaked with watery lines, attenuated below, or subequal ; 

 bulbous when very young. Spores elliptic. Smell strong, 

 like Marasmius oreades. (Berk.) 



Boletus granulatus. Linn. 



Pileus 3-4 in. across, convex, then more or less expanded, 



at first viscid with reddish-brown gluten, yellowish when 



the gluten has disappeared ; tubes up to ^ in. long, adnate 



and often with an indication of being decurrent, yellow.
