On dead wood. 
Forming elongated, more or less interrupted, erumpent - 
patches, many inches long, plane, slightly raised, black, with | 
a smoky bloom; black within, brittle and carbonaceous, sut- :

Resembling in habit Spheria stigma, but differing in ita 
dark stroma, smoke-like bloom, and above all, in its elliptic, f 
brown, not curved, and pellucid sporidia. The whole plant 
looks exactly as if it had been smoked over a candle. à 
A very curious new genus was sent by Mr. Dora 
amongst the Fungi, allied to Collema, but with the outward | 
habit, and in some respects the structure, of a Dothidea. Ont 
species is identical with a plant gathered by Dr. Monta 
many years since, without fructification, in the department of | 
the Eastern Pyrenees, on the white mulberry, and has 
been found in Algiers on the Lentiscus; the other species has 
at present been found at the Swan River only.
