25. C. scaurus Fr. Pileus commonly 5-7.5 cent. (2-3 in.), very 

 rarely 10 cent. (4 in.) broad, tiger-spotted, of a peculiar tawny- 

 fuliginous colour, when dry more tawny, fleshy, convex then 

 plane, depressed when old, viscous, smooth, the thin margin at 

 length slightly striate; flesh thin, soft. Stem solid, soft and 

 spongy (especially the bulb) with age, equally attenuated upwards 

 from the marginato-bulbous base (more than 2.5 cent., I in. thick 

 at the base, 8 mm., 4 lin. at the apex), fibrillose or striate, azure- 

 blue or olivaceous then becoming white, and also yellowish when 

 old. Cortina fibrillose, somewhat green. Gills attenuato-ad-
