10 AGARICINI. 



Phlegma- and there obliterated with age, always white beneath. Neither the gills when 

 cium. bruised nor the flesh when broken ever change colour (intensely azure-blue), 



but the gills become purple and at length cinnamon. Odour scarcely any. 



In mixed woods. Frequent. Aug.-Nov.

18. C. purpurascens Fr. Pileus 10-12.5 cent. (4-5 in.) broad, 

 bay-brown or date-brown-olivaceous, then tawny-olivaceous, tiger- 

 spotted, and often depressed round the margin, which is at first 

 inflexed then repand, marked with a raised fuscous zone, fleshy, 

 compact at the disc, obtuse, repand, variable, smeared with dense 

 gluten, but opaque when dry; flesh wholly azure-blue. Stem 

 solid, thick, bulbous, wholly fibrillose, intensely pallid azure-blue, 

 darker when touched, bulb somewhat marginate. Gills broadly 

 emarginate, 6 mm. (3 lin.) and more broad, crowded, azure-blue- 

 clay, then cinnamon, violaceous-purple when bruised. 



Readily distinguished from species near to it (especially C. glaucopus) by its 

 gills soon changing colour and becoming spotted -with purple when touched. 

 The primary form is curt, robust, very compact, juicy, azure-blue-purplish 

 when touched. There is another form, in dense beech woods, somewhat 

 caespitose, the longer stem somewhat twisted, pileus undulated, as much as 

 20 cent. (8 in.) broad, toast-brown then clay-colour and at length cinnamon 

 with the spores. Gills at first bluish-grey-purplish ; otherwise as above. 



In mixed woods. Common. Sept.-Nov.

* C. subpurpurascens Fr. Pileus tawny-fuliginous, becoming 

 pale, not compact, obtuse, at length very much dilated and 

 undulato-flexuous, viscous, obsoletely streaked with fibrils, some- 

 what spotted ; flesh soft, whitish (very faint azure-blue), un- 

 changeable. Stem 7.5-10 cent. (3-4 in.) long, 12 mm. ( l / 2 in.) 

 thick, at length hollow, somewhat cylindrical, marginato-bulbous 

 at the base, fibrillose below, naked above, smooth, slightly striate, 

 pale azure-blue or whitish. Gills sometimes emarginate, almost 

 free, sometimes decurrent,/<?//zV/ then cinnamon, becoming purple 

 when bruised.
