Hygrophorus virgineus (Wulf.) Fr. 



WHITE HYGROPHORUS 

 State Mus. Mem. 3, p. 150, pi. 52, fig. 8-12. 



Pileus fleshy, convex, often becoming plane or centrally depressed, 

 sometimes irregular or wavy on the thin margin, moist, white, flesh 

 white, taste mild ; lamellae thick, distant, decurrent, white ; stem 

 firm, smooth, solid, equal or tapering downward, white ; spores 

 elliptic, .00024-.0003 of an inch long, .0002 broad. 



Pileus 1-3 inches broad ; stem 1-2 inches long, 3-5 lines thick. 



It occurs in grassy places in wet weather and may be found from 

 July to October. Albany, Essex and Rensselaer counties. In the 

 European plant the surface of the pileus is said to become floccose 

 when dry and sometimes to crack into small areas, but these charac- 

 ters have not been observed by us in the American plant. It is 

 edible. 



Hygrophorus borealis Pk. 



NORTHERN HYGROPHORUS 



State Mus. Rep't 26. 1874. Bot. ed. p. 64. 



Pileus thin, convex or nearly plane, glabrous, moist, even, some- 

 times striatulate on the margin ; lamellae distant, arcuate, decurrent, 

 white; stem slender, firm, glabrous, straight or flexuous, equal or 

 tapering downward, stuffed or solid, white ; spores elliptic, .0003- 

 .00035 of an inch long, .0002-.00024 broad. 



Pileus 8-12 lines broad ; stem 1-2 inches long, 1-2 lines thick. 



Damp or moist ground in woods and swamps, occasionally in pas- 

 tures. Common in hilly and mountainous regions. July to October. 

 This small white species is closely allied to H. niveus (Scop.) 

 Fr. from which it may be separated by its pileus which is neither 

 viscid nor umbilicate.
