Family 65. AGARICACEAE 



Pileus typically cap-shaped and stalked, rarely sessile and the hymenium above, 

 fleshy to corky ; pileus sometimes enclosed in a cap veil which persists at the base 

 of the stipe as a volva ; hymenium consisting of radiating lamellae or gills, often 

 protected by a gill veil which remains on the stipe as a ring; gills covered with 

 basidia, bearing typically 4 sterigmata and spores ; spores typically i-celled, hyaline 

 or colored. 



Leucosporae 



5:8, 9:1, II : I, 14:63, 16:1, 18:1 

 Spores colorless, or very dilutely colored even in spore prints, globose to fusoid, 



smooth or rough 



I. Edge of the gills entire, riot canaliculate or split 

 I. Fleshy, putrescent, not reviving when wet 

 a. Edge of the gills acute, not fold-like 



(i) Trama of the pileus not vesiculose; spores typically smooth 

 (a) Gills more or less fleshy, readily separable into two layers 

 X. Stipe central or nearly so 



(x) Hymenophore discrete from the fleshy stipe 

 m. Stipe volvate
