Leucosporee 



of the following species which are of the same color. Pileus at length 

 becoming yellow. Stevenson. 



Spores 10 i2x6/A Cooke; 7x4/1* Morgan. 



Edible. Cooke, Peck. 



In woods and pastures. In troops. Common in West Virginia, Penn- 

 sylvania, New Jersey. Mcllvaine. 



Excellent when stewed for twenty minutes. 



H. fla'vo-dis'cus Frost flavus, yellow; discus, disk. Pileus convex 

 or plane, smooth, glutinous, white (Plate XXXIX.) 

 with a pale-yellow or reddish-yellow 

 disk. Flesh white. Gills adnate or 

 decurrent, subdistant, white, some- 

 times with a slight flesh-colored tint, 

 the inter-spaces sometimes veiny. 

 Stem subequal, solid, glutinous, 

 white, sometimes slightly stained with 

 yellow. Spores elliptical, 6-8x4;*. 



Plant 2-3 in. high. Pileus 1-3 in. 

 broad. Stem 2-8 lines thick. 



Pine woods. West Albany. No- 

 vember. 



This, like H. fuligineus, has a 



short white space at the top of the stem, free from the viscidity that 

 exists elsewhere. It resembles in many respects Hygrophorus spe- 

 ciosus, which has the pileus red, fading to yellow with advancing age. 

 Perhaps the three may yet prove to be forms of one very variable 

 species, for the most conspicuous differences between them consist in 

 the colors of the pileus. The constancy with which the three styles of 

 coloration has thus far been maintained indicates a specific difference, 

 but color alone is not generally regarded as having any specific value.

Spores 6.4-7.6x4^ Peck. 



I find this very good but its dirty pellicle should be peeled before 

 using. Peck, in letter, 1896. 



Mr. Hollis Webster writes of H. flavo-discus (Yellow Sweet Bread) 

 in Bull. No. 45, of the Boston Mycological Club, 1897: "This is a 

 mushroom worth going a long way to get. It is abundant in rich woods
