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. (J4 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, pallid then cinnamon, becoming purple 

 when bruised.
