 G. Favosi. Tubes large, angular, unequal, &c. 



33. B. laricinus Berk. Pileus 5-7.5 cent. (2-3 in.) broad, 

 dirty white, with livid stains, covered at first with dirty-yellow 

 or brownish evanescent slime, somewhat scaly; flesh white, very 

 slightly tinged with yellow. Stem 5 cent. (2 in.) or more long, 

 12-16 mm. (%- 2 A in.) thick, cribrose above the ring, pitted below, 

 dirty white. Tubes adnate, somewhat decurrent, compound, at 

 first nearly white.

34. B. viscidus Linn. Pileus ttmgy yellowish, pulvinate, soft, 

 smooth, viscid ; veil somewhat annular, torn, white, somewhat 

 appendiculate. Stem viscous, white becoming yellow, thickened 

 at the base, reticulated above. Tubes adnate ; pores large, un- 

 equal, livid. 



Perhaps too nearly allied to B. laricinus. The stem often appears torn 

 from the agglutinated fragments of the veil. 



In woods. Rare. 



Spores fuscous-black. Fr.; spindle-shaped, elongated, brownish green, 

 9x3 mk. W.G.S. Name viscum, bird-lime. Viscid. Linn. Fr. Hym.

H. Versipelles. Tubes minute, round, equal, &c. 



35. B. versipellis Fr. Pileus rufous, pulvinate, dry, at first 

 compact and tomentose, then scaly and becoming even, appendicu- 

 late with the annular, membranaceous, fugacious veil. Stem 

 solid, attenuated upwards, wrinkled-scaly. Tubes free, plane, 

 minute, dingy white ; pores grey. 



Truly distinct from B. scaber, but it is difficult to define exactly the differ- 

 ence between them on account of analogy in colour and variation in stature. 

 The colour of B. versipellis is more constantly rufous. 



In woods and heath. Frequent. Aug.-Oct.
