STUDIES OF AMERICAN FUNGI. 



minute hairs, at the base with long hairs, hollow, in color the same 



as that of the pileus. 



The color varies some- 

 what, being darker in some 

 plants than in others. In 

 some plants the juice is more 

 abundant and they bleed 

 profusely when wounded, 

 while in other cases there 

 is but little of the juice, 

 sometimes wounds only 

 showing a change in color 

 to a deep red without any 

 free drops exuding. Figure 

 102 is from plants collected 

 at Ithaca, in August, 1899. 

 It is widely distributed in 

 Europe and North America. 

 Mycena succosa Pk. , 

 another species of Mvccna 

 with a juice, occurs on very 

 rotten wood in the woods. 

 It is a small plant, dull 

 white at first, but soon 

 spotted with black, and 

 turning black in handling 

 or where bruised, and when 

 dried. Wounds exude a 

 "serum-like juice," and the 

 wounds soon become black.

It was described by Peck 

 under Collybia in the 25th 

 Report, p. 74. 



OMPHALIA Fr. 



The genus Omphcilia is closely related to Mycena and Collybia. 

 It differs from these mainly in the decurrent gills. In the small 

 species of Mycena where the gills are slightly decurrent, the pileus is 

 not umbilicate as it is in corresponding species of Omphalia. In some 

 of the species of Ompbalia the pileus is not umbilicate, but here the 

 gills are plainly decurrent. The stem is cartilaginous.
