a. On the stems of UmbellifercE — b. On petioles of Sparganium, 

 Sagittaria, &c.— Of the two plants of Sowerby, quoted above, the first 

 is desciibed as growing on the stems of Umbdliferce : of this no speci- 

 mens remain. Of the latter a sample is preserved on the petiole of a 

 Sparganium; but I doubt very much, judging from his specimens on 

 Nardus in Scler. Siiec, whether it is what Fries intends, and indeed 

 if it be any thing more than *S'. scirpicola, Dec.

On Ivy-leaves. Appin, Captain Carmichael. Durham, W. C. Tre- 

 velyan, Esq. — Known from other minute Sphcei-im on Ivy-leaves, by 

 its shining immersed perithecia and white ostiola. In Dr. Johnston*s 

 Fl. j3erw. a minute Sphceria is inserted under the name of S. Empetri^ 

 and the same plant has been found near Edinburgh by Dr. Greville. 

 It is clearly not the plant of Fries, being very much smaller and not 

 collapsed. 



193. S. artocreas, Tod. {raised-pie Sphceria); gregarious 

 innate orbicular black shining, at first convex even, soon 

 depressed round the dot-like ostiolum, at length collapsed and 

 rugoso-plicate. Tode, Fung. Mtck. 2. p. 20. f. 73. Fr. Syst,

On dry leaves of various trees, especially Beech. Common. — Having 

 when old completely the appearance of an obscure Sclerotium or 

 Dothideay so as to require an accurate and minute examination to refer 

 it to its proper place. 



194. S. recutita, Fr. {half-naked Sphceria) ; aggregate hypo- 

 phyllous innate but slightly prominent very minute mouthless 

 black, appearing under the form of very long parallel strise. 

 Fr. Syst. Myc. v. 2. p. 524. 



On leaves of Grass. Near Berwick, Dr. Johnston. — The pei'ithecia 

 grow in rows, but are quite distinct. 



195. S. macidcBformis, Fers. {spot- like leaf Sphcsria) ; hypo- 

 phyllous, perithecia innate but slightly prominent punctiform 

 globose black crowded together into an unequal spot. Fers.
