32. C. arvinaceus Fr. — Pileus 7.5-10 cent. (3-4 in.) broad, 

 orange-tawny, fleshy, soft, convex then soon flattened, at length 

 reflexed and undulated, even, smooth, 

 viscous (not glutinous), glistening 

 when dry, margin slightly striate 

 when in full vigour. Stem tall, as 

 much as 20 cent. (8 in.) long, 12 

 mm. {% in.) thick, solid, equal, silky- 

 viscous, never broken up into scales, 

 white. Cortina soon fibrillose and fu- 

 gacious. Gills adfiato-decurrent, very 

 broad (12-18 mm., %.-% in.), even at 

 the sides, somewhat distant, cre?iu- 

 lated at the edge, at first straw-colour 

 then bright ochraceous. 



Spores plentiful, of the same colour as 

 the gills. Cortina not in the form of a ring. 

 Perhaps too nearly allied to C. collinitus.

33. C. collinitus Fr. — Pileus orange-tawny, fleshy, not com- 

 pact, convex with the margin bent inwards then expanded, 

 obtuse, clothed with a thick cuticle, which in wet weather swells 

 into persistent orange-taw?iy gluten, shining when dry, margin 

 even. Stem solid, firm, elongated, exactly cylindrical, at length 

 soft, for the most part covered over with ^.floccose and glutinous 

 veil, which is commonly broken up into conce?itric scales j near 

 the apex the gluten is continuous with the glutinous cuticle of 

 the pileus and forms an entirely viscous fugacious ring, colour 

 variable, violaceous, white, even yellowish. Gills adnate, some- 

 what crowded, whitish-bluish-grey or clay-colour theft cinnamon. 



There are numerous forms departing from the type : b) pileus repand, stem 

 inclining to fuscous: Batsch f. 197. c) small, pileus pallid yellow or straw -
