This hygrophorus is a beautiful mushroom when fresh but its 

 cap and gills change color in drying, by which it loses much of 

 its beauty. Both cap and stem are smeared with a 

 viscid substance or gluten that makes it unpleasant to 

 handle. In the typical form the cap is white except 

 in the center where it has a reddish or brownish tinge 

 which sometimes spreads faintly toward the margin, but 

 there is a variety in - which the cap is entirely white 

 or only faintly tinged with j^ellow. We have named this variety 

 unicolor. Sometimes the center is slightly prominent or 

 umbonate and the margin is irregular or wavy. The gills are 

 decurrent and rather wide apart. They are white when fresh, 

 but like the cap they become brown or reddish brown in drying. 

 The stem is white or nearly so, solid, commonly tapering to a 

 point at the base but sometimes nearly equal in all its parts. 

 Its viscidity makes it difficult to pull the plant from its place of 

 growth with the fingers. 



The cap is 1-4 inches broad; the stem 1-4 inches long and 2-6 

 lines thick. This mushroom grows among fallen leaves in woods 

 and appears during August and September. It appears to be 

 peculiar to this country. It is related to the ivory hygrophorus 

 and the goat moth hygrophorus of Europe but from the former 

 it differs in its solid stem, elliptic spores and change of color in 

 drying and from the latter by the absence of odor. I have eaten 

 the white form only, but give a figure of the other also.
