Hygrophorus flavodiscus Frost 

 Yellow-disked Hygrophorus 



Plate 56. Figure ii, X i 



Pileus fleshy, convex or nearly plane, 3-8 cm. broad ; surface 

 glabrous, very viscid, white with pale-yellow or reddish-yellow 

 center; flesh white; lamellae adnate or decurrent, subdistant, 

 white, slightly tinged with flesh-color at times, the interspaces 

 sometimes venose ; spores ellipsoid, smooth, hyaline, 6-7.5 X 

 4-5 fx ; stipe subequal, solid, very viscid, white at the apex, white 

 or yellowish below, 3-8 cm. long, 6-12 mm. thick. 



A beautiful species, occurring in woods in autumn. Peck pub- 

 lished it with Frost's name and notes in the 35th annual state 

 report, the plant being represented at the time by specimens from 

 Vermont and New York.

Pileus of developed form fleshy, firm, convex to nearly plane 

 or slightly depressed, usually entire on the margin, gregarious or 

 cespitose, 5-10 cm. broad, the sporophores very commonly repre- 

 sented by subglobose aborted masses of cellular tissue 3-6 cm. in 

 diameter; surface of developed form dry, silky-tomentose, be- 

 coming glabrous, gray or grayish-brown; flesh white, with fari- 

 naceous odor and taste ; lamellae adnate, close, thin, strongly de- 

 current, whitish or pale-grayish, changing to salmon-colored; 

 spores angular, uninucleate, salmon-colored, 8.5-10 X 6-7.5 /;i ; 

 stipe subequal, solid, slightly flocculose, longitudinally striate, con- 

 colorous or paler than the pileus, 3.5-8 cm. long, 5-12 mm. thick. 



Common on rich earth or much decayed wood in woods during 

 late summer and autumn, from Canada to Alabama and west to 

 Wisconsin and Mexico. It was very abundant about New York 

 last September. It is an excellent edible species both .in its fully 

 developed and aborted forms, the latter being gathered by the 

 Indians for the market in some parts of Mexico.
