lary, 4 to 6 to one millimeter ; spores globose, tuberculate, 5-6 p 
wide, dark colored ; taste bitter.

The type specimens are the U. & А. 598 at the New York Bot- 
anical Garden. Тһе plant is closely related to 5. fennicus 
Karst. differing from that species in its radicating stem, the finer 
teeth and the dark horny appearance of the flesh when dried; 
the dark color at the base of the stem also appears to be lacking. 
The teeth in the dried plant are very brittle so that herbarium 
specimens are often denuded. The plant has been generally re- 
ferred to 5. imbricatus but its only claim to such disposition is 
the fact that it has a scaly pileus. One set of Ellis N. Am. F ung. 
contained a large specimen of this species under 926 (H. imbri- 
catum L.)

The type specimens which are in Morgan’s herbarium were 
collected by Atkinson “on old wood,” an unusual habitat for this 
genus. They were said to be dark green throughout even to the 
spores. Earle's plants were found on the ground in woods. No 
greenish color was observed about these plants when fresh, but
