Pileus 5-10 lines broad; stem 1-4 inches long, 1-2 lines thick. 



Plants scattered or gregarious, often odorous. Woods and open 

 places. Hamilton, Saratoga and Tompkins counties. July and 

 August. 



The green color is due to the gluten and it quickly disappears 

 when the gluten dries. The species is closely related to H. 

 psittacinus Fr. from which it may be separated by the pileus 

 which is neither campanulate nor umbonate and by the lamellae 

 which are paler, less ventricose and more decurrent. The plant is 

 very fragile and must be handled carefully to prevent breaking. 

 In color it resembles H . 1 a e tu s (Pers.) Fr. 



Hygrophorus psittacinus (Schaeff.) Fr. 

 PARROT HYGROPHORUS 



Pileus thin, conic or campanulate becoming nearly plane, some- 

 what umbonate, striatulate, covered when young with an evanescent 

 greenish gluten, yellowish, reddish or whitish; lamellae thick, sub- 

 distant, ventricose, adnate, yellow, more or less tinged with green; 

 stem tough, even, hollow, viscid, green at the top, yellow below; 

 spores .0003 of an inch long, .0002 broad. 



Pileus 6-12 lines broad; stem 1-2 inches long, 1-2 lines thick. 



Pastures, swamps and clearings, often under brakes, P t e r i s 

 a q u i 1 i n a L. Lewis county. September to November. Rare 



The green color is generally more persistent at the top of the 

 stem than elsewhere, both in this and in the preceding species.

 State Mus. Rep't 26. 1874. p. 63. 



Pileus thin, fragile, conic becoming expanded and cupulate by 

 the upcurving of the thin margin, very viscid, often irregular, white ; 

 lamellae subdistant, broad, ventricose, emarginate with a decur- 

 rent tooth, white; stem glabrous, subflexuous, fragile, hollow, very 

 viscid; spores .0003 of an inch long, .0002 broad. 



Pileus 1-2 inches broad ; stem 3-6 inches long, 2-3 lines thick. 



Thin woods. Lewis county. September. Rare. Found but 

 once. 



H. calyptraeformis niveus Cke. scarcely differs from
