soil; Great Willey Slide; also with B. byssoides on the sandy 
banks of the Ammonoosuck, near Mount Washington. Re- 
markable for possessing an orbicular lobed thallus, like that 
of some Parmeliz, together with stipitate apothecia, like those 
of Beomyces. It has hitherto been found only in Lapland by 
Wahlenberg, and in Norway by Professor Blytt.

This striking feature is owing to the black hypothallus. I 
have several interesting Biatoree under examination.

Mountains. The description of Acharius is so brief, that I
