Agaric on which it grows, and indeed the wliole plant, juicy, so that it 

 soon becomes putrid. Perithecia irregularly immersed, at length 

 emergent minute. Surface even, frosted with a thin whitish meal." 

 Fr. I. c. I am obliged to rest entirely on the authority of Fries for the 

 right determination of the [dant of Sowerby, of which no specimens 

 were preserved, probably on account of the rapid decomposition above- 

 mentioned.

On wood. Appin, Captain CarniichaeL — Amongst numerous spe- 

 cimens marked S. ruhiginosa, from Appin, which are a form of 5'. ynidti- 

 furrnis, one appears to be the true plant. " Forming longitudinally 

 effused spots, 2 — 4 inches long, at first pulverulent and dirty yellow. 

 When full-grown densely covered with rust-coloured powder, at length 

 naked and black ; perithecia small umbilicate at the apex, almost free. 

 Sometimes the perithecia arc solitary larger distant and papillary, 

 ^largin barren." Fr. I. c. 



24. S. atropurpurca^ Fr. (purplish-blacJi Sp/tccria) ; effused 

 tliin flattened purplish-black, perithecia connate rather pro- 

 minent, apex plane papillate. Fr. Ohs. I. p. 174. Scler. Suec. !

On rotten wood. A|)pin, Captain Curmichatl. — Perithecia larger 

 and more prominent than in the following species, with scarcely any 

 stroma, t^ometunes the perithecia are scattered, or arranged in lines.

On wood, branches, I've. Appin, Cajttain Carmichacl. Northamp- 

 tonshire, P(v. 31. J. Bcrhchi/. — At first clothed with tliin, cinereous, 

 mealy down, at lengtii naked, *2 — .'i inches or more long. Of the two 

 figures in Sowerby, the fir^t certainly is this plant ; as rcgarils the 

 second 1 follow the judgment of Fries, there being no specimen in 

 Mr. Sowerby's collection.
