DISTRIBUTION OF LICHENS IN TROPICAL 
AMERICA. 
Dr. Adrian de Krempelhuber, of Munich, has, throughout the 
volume of the Regensburg Flora for 1876, described a magnificent 
collection of Lichens amassed by Dom. A. Glaziou, Director of the 
Public Gardens of Rio de Janeiro, from the maritime shores, lofty 
mountains (2330-2714 ft.), and woods of the province of Rio 
Janeiro. The collection numbers 350 species, of which 110 species 
are new, and belong to the genera — Phylliscum, 1 ; Heterina, 1 ; 
Trachylia, 1 ; Basomyces, 1 ; Sticta, 1 ; Lecanora, 9 ; Urceolaria, 
1 ; Pertusaria, 5 ; Phlyctis, 2 ; Thelotrema, 10 ; Ascidium, 2 ; 
Ccenogonium, 3 ; Lecidea, 19 ; Graphis, 33 ; Platygrapha, 1 ; 
Opegrapha, 4; Arthonia, 4 ; Chiodecton, 2 ; Verrucaria, 7 ; Try- 
petheliuin, 1 ; Astrothelium, 1. 
The following tabular conspectus, compiled from various sources, 
enables us to obtain a very fair approximation of the distribution 
of Lichens over the various provinces of the northern or tropical 
region of ^outh America : —

It should be remembered that the above table affords only an 
approximation, because, with the exception of Dr. Glaziou’s Collec- 
tion, the others comprise scarcely any, if any, saxicolar lichens.
