and the surface of the gill can be rather easily removed, leaving the 

 projecting line of the trama. This is more marked in some species 

 than in others. The waxy consistency of the gills then, with the 

 gills acute at the edge, broad at the point of attachment to the pileus, 

 and the gills being rather widely separated are the important charac- 

 ters in determining the species which belong to this genus. The 

 nearest related genus is Cantharellus, which, however, has blunt 

 and forked gills. A number of the plants are brilliantly colored. 



Hygrophorus chrysodon (Batsch.) Fries. Edible. This plant has 

 about the same range as Hygrophorus eburneus, though it is said to be 

 rare. It is a very pretty plant and one quite easily recognized 

 because of the uniform white ground color of the entire plant when 

 fresh, and the numerous golden flOccules or squamules scattered over 

 the cap and the stem. The name chrysodon means golden tooth, and 

 refers to these numerous golden flecks on the plant. A form of the 

 plant, variety leucodon, is said to occur in which these granules are 

 white. The plant is 4-7 cm. high, the cap 4-7 cm. broad, and the 

 stem 6-10 mm. in thickness. The plants grow on the ground in the 

 woods, or rather open places, during late summer and autumn. 



The pileus is convex, then expanded, the margin strongly involute 

 when young, and unrolling as the cap expands, very viscid, so that 

 particles of dirt and portions of leaves, etc., cling to it in drying. 

 The golden or light yellow granules on the surface are rather num- 

 erous near the margin of the pileus, but are scattered over the entire 

 surface. On the margin they sometimes stand in concentric rows 

 close together. The gills are white, distant, decurrent, 3-6 mm. 

 broad, white, somewhat yellowish in age and in drying, and con- 

 nected by veins. The spores white, oval to ovate, the longer ones 

 approaching elliptical, 6-10 x 5-6 yw. 



The stem is soft, spongy within, nearly equal, white, the yellow- 

 ish granules scattered over the surface, but more numerous toward 

 the apex, where they are often arranged in the form of a ring. 

 When the plant is young these yellow granules or squamules on the 

 stem and the upper surface of the inrolled margin of the pileus meet, 

 forming a continuous layer in the form of a veil, which becomes 

 spread out in the form of separated granules as the pileus expands, 

 and no free collar is left on the stem.

Hygrophorus eburneus (Bulliard) Fries. Edible. This plant is widely 

 distributed in Europe and America. It is entirely white, of medium 

 size, very viscid or glutinous, being entirely covered with a coating
