Agaricaceee 



ARMILLARIA MELLEA. 



ARMILLA'EIA Fr. 



Armilla,3i ring. 



ArmiUaria. PileilS and Stem continuous. Veil partial, sometimes only indicated 



(Plate XVII.) by the scales which clothe the stem 



terminating in the form of a ring. 

 Spores white. On the ground or on 

 stumps. 



In the young plant the veil extends 

 from the stem to the pileus, some- 

 times forming scaly patches upon it ; 

 below the ring it is attached to the 

 stem often in scales. 



But for the presence of the ring 

 the species of this genus could be dis- 

 tributed in Tricholoma, Clitocybe and Collybia, with which they agree 

 in all other characters. 



In Amanita and Lepiota, the other ringed genera of the white-spored 

 series, the flesh of the stem and pileus is not continuous; and their stems 

 are therefore easily separated. Amanita is also distinguished by its 

 volva. 



ANALYSIS OF TRIBES. 



TRICHOLOMATA. Page 52. 



Gills sinuately adnexed, stem fleshy, ring often evanescent. (Like 

 Tricholoma.) 



CLITOCYBE. Page 55- 



Gills not sinuate, more or less decurrent, narrowed behind ; ring per- 

 manent. (Resembling Clitocybe.) 



COLLYBLE. Page 58. 



Gills adnate, equal behind; stem somewhat cartilaginous outside; 

 ring permanent. (Resembling Collybia.) 



I. TRICHOLOMATA. Gills sinuately adnexed, etc. 



A. robus'ta A. and S. robustus, robust, sturdy. Substance of entire 

 plant compact. Pileus 23 in. across, varying in shades of gray and
