Systematic Description of the Species of Agaricaceae 
(Toadstools and Mushrooms and other Gilled Fungi). 
BASIDIOMYCETAE. 
Fungi reproduced by spores borne on basidia. 
HOMOBASIDIAE. 
Basidia simple ; spores on germination giving rise to a mycelium. 
EU-HOMOBASIDIINEAE. 
Saprophytes. 
HYMENOMYCETALES. 
Hymenium at first covered by a universal or partial veil becoming fully 
exposed at maturity, or exposed from the first, spread over the surface of gills, 
pores or teeth, or over a smooth or rough surface. 
AGARICACEAE. 
“Hymeniuan spread over the surface of gills radiating from a stem or a 
central point. Receptacle fleshy, or membranaceous or coriaeeus, fragile 
or firm or tough, putrescent or not putrescent, reviving with moisture or not, 
and sometimes containing laticiferous vessels; consisting of a pileus with or 
without a central or lateral stem, and sometimes with a volva or ring, and with 
broad gills acute at the margin or narrow obtuse gills or folds. Growing on 
the ground or on wood ’ ’ — Rea. 
I. Hymenium inseparable from the pileus, spread over the surface 
of broad gills acute at the margin. 
1. Receptacle fleshy, trama not vesiculose and not traversed by laticiferous 
vessels, not membranaceous, not rapidly putrescent, not tough or woody. 
A. SPORES WHITE. LEUCOSPORAE. 
(a) Pileus distinct from and easily separable from the fleshy stem. 
*With a ring on the stem and a volva at the base of the stem. 
AMANITA (Pers.) Er. 
(Probably from Mount' Anmnus in Cilicia.) 
‘ ‘ Pileus fleshy, regular. Stem central, fleshy. Ring membranaceous, adnate, 
persistent or rarely fugacious. Volva membranaceous, free or adnate, persistent 
or friable. Gills free or subadnate or decurrent by a tooth, intermediate gills 
cut squarely behind. Spores white rarely tinged greenish, globose or subglobose, 
or oval or elliptical, smooth or very rarely verrucose. Cysitilia subglobose or 
cylindrical ventrieose. Growing on the ground.” — Rea.
