obtuse, 3 in. across, viscid, tawny, sprinkled with seceding, 

 superficial, paler scales, by which character it is distinguished

 Hdbk., p. 144; Cke., Illustr., pi. 366. 



On trunks, chiefly birch. Somewhat resembling PJioliota 

 comosa, but distinguished at once by the strong, pungent, 

 horse-radish odour. Solitary according to Fries, but in 

 Cooke's figure three specimens are connate at the base of the 

 stem, the pilleus and stem are also dingy brown. 



Solitary, compact, odour strong, pungent, almost like 

 horse-radish. Stem solid, firm, stout, but short, about 2 

 in., base bulbous-incrusted, and praemorsely rooting, 

 ^-1 in. thick, fibrillose, white, commonly curved and ascend- 

 ing, apex veiled, base rhubarb-colour within. Veil very 

 rarely forming a perfect ring at the apex of the stem, com- 

 monly appendiculate from the margin of the pileus, floccoso- 

 radiate, and always forming a zone round the stem. Pileus 

 fieshy, compact and hard when young, often excentric, 

 hemispherical then expanded, very obtuse, 2-3 in., then 4—5 

 in. across, sometimes even, generally broken up into broad, 

 scattered, innate, adpressed, spot-like (darker) scales, whitish 

 or yellow, when old sometimes tawny, sometimes viscid. 

 Flesh thick, firm, pallid. Gills rounded behind, slightly 

 adnexed, very broad, plane, crowded, at first pallid, then 

 dingy ferruginous. (Fries.)
