Mr. Gardner. 
This is one of the most remarkable Lichens with which 
I am acquainted, and the same structure prevails in all the 
numerous specimens sent to me by Mr. Gardner. At first I 
was disposed to refer it to the Cladonia perfoliata of Martius, 
but a more careful comparison with the description and a refer- 
ence to the figure of that species in Raddi’s * Memoir on Bra- 
zilian plants,” (¢, 3. f 4.) has convinced me that it is a totally 
different plant. The scyphi, if such they may be called, are 
almost exactly orbicular, developing as the podetium developes, 
at first small and convex, then larger and plane, beautifully mar- 
gined with black fimbriz, at length reflexed, frequently in a 
triangular manner as represented at. 1. The colour is green- 
ish-white, often tinged with brown.
