AMANITA. 21 



size, and shape. These are white (Leucospori), salmon or pink 

 (Hyporhodii), brown or argillaceous (Dermini), dark purple 

 (Pratellae), black (Coprinarii). Each spore color series is sub- 

 divided into subgenera according to certain characters of the 

 veil, gills, stem, etc. These subgenera are now elevated to 

 the rank of a genus, and Agaricus is only retained in place of 

 subgenus Psalliota which is dropped. 



The following is a list of the Leucospori or white-spored 

 Agarics. 



Amanita. Fr. 



This subgenus, or now considered as a good genus, heads the 

 list of the white-spored Agaric, characterized by a universal 

 volva or wrapper and a partial veil forming in some species an 

 annulus. The volva enclosed the whole plant when young, 

 and the remains of it are seen after development on cap and 

 stipe. 



C. G. Ivloyd, of Cincinnati, Ohio, a colaborer in the study of fungi 

 with me, has recently published a compilation of the Amanita family of 

 the United States, has made use of Worthington Smith's arrangement of 

 the groups of the genus Agaricus, viz : 



Series I. 



Pileus distmd from the fleshy stem. 

 Plant furnished with a volva = Volvae. 

 Plant without a volva, ring present, Annulse. 

 Plant without volva or ring, Exannulse. 



Series II. 



Pileiis confluent with the fleshy stem. 

 Plant with a ring, stipe central, Armillse. 



Plant without a ring, gill attached to stem with a sinuate tooth, DenUe. 

 Plant without a ring, gills decurrent, stipe central, Clivoe. 

 Plant with stipe eccentric, Exccntrse. 



Series III. 



Stipe cartilagiiioiis. 

 Gills not decurrent, pileus explanate, margin at first involute, Explange.
