altered by moisture. Apothecia on the scales, at first 
flat and bordered as in Lecidea, soon, however, globose, 
and excluding the border, rough, subpruinose, crowded; 
they are supported on a stipes of white cortical matter 
immersed in the crustaceous scales. Disk black, covering 
a very shallow, semi-transparent, striated lamina, resting 
on much black matter. Closely allied to B. anomalus, 
Tayl, in Flor. Hib., which now ceases to be singular for 
having no conspicuous stipes; and which has the crust 
whiter and thinner, as well as more even, while the 
apothecia are paler, and when full grown not so convex. 
2. B. hyalinus, Tayl.; thallo crustaceo, minuto, sublobato, 
pallide flavo-virescenti; gemmis subrotundis, apice fuscis; 
stipite compresso, subrugoso, madore hyalino, punctis 
opacioribus consperso; apotheciis subplanis, pallidissime 
Carneis, margine albido, subintegerrimo. 
Has. On sandy clay; Swan River; Mr. James Drummond.

oftener oblong than round. Stipes about half an inch  —
