AGARICACEAE, Fries. 



Hymenium covering the entire surface of radiating lamellae or 

 gills. Spores one-celled. 



Primary divisions of the Agaricaceae depend on the colour of the 

 spores as seen in the mass, when deposited on an opaque substance ; 

 and not as seen under the microscope by transmitted light. 



I. LEUCOSPORAE. 



Spores white. In some cases with a tinge of yellow or pink. In 

 some species of Russula the spores are clear ochre, but such species 

 belong obviously to Russula notwithstanding. 



II. CHLOROSPORAE. 



Spores clear green or bluish -green. 



III. RHODOSPORAE. 



Spores salmon-colour or pink. 



IV. OCHROSPORAE. 

 Spores ochraceous or rust-colour. 



V. MELANOSPORAE. 



Spores black, blackish-brown, or black with a purple tinge. 



LEUCOSPORAE. 

 I. HAPLOPHYLLAE. 



Margin of gills acute ; i.e. not longitudinally split or grooved. 



* MOLLES. More or less fleshy, soft, and soon decaying 

 or shrivelling (not corky, woody, or rigid). 



f Ring, or volva, or both present, or gills free. 



Amanita. Volva and ring present. Gills usually free, rarely 

 adnexed or adnate. (Volva sometimes not evident round base of 

 stem, but loose patches on pileus prove its presence.) 



Amanitopsis. Volva present, ring absent; gills free.
