On hranchcs oi Rosacea'. Perennial. Common in Scotland. Bagley 

 wood, Oxford. On crab trees destroyed by the sedge having taken 

 fire, Mr. Baxter. — Peziza populnea, Pers., quoted by Dr. (Jreville 

 under this species, belongs to Peziza fascicidaris. The generic cha- 

 racter, as given in the Scottish Crypt. FL, scarcely embraces the dis- 

 tinguishing feature of the genus, which is that the hymenium at length 

 breaks up and becomes deintegrated. 



33. Cenangiuji. Fr. Cenangium. 

 Hymenium even, persistent, rarely deliquescent. Cup closed, 

 at length open, more or less coriaceous, consisting of two 

 distinct coats, the outer coriaceous or membranaceous, the inner 

 subgrumous. — Named from -/.zni-, empty., and ayyi'io'i, a vessel. 



1. C. Cerasi, Pers. {Cherry-tree Cenangium) ; subcjespitose, 

 of no determiuate form, at first tuberculate rugose argillaceo- 

 rufous, at length unfolding into blackish cups which are plane 

 above. Fr. Syst.Myc. v. 2. p. 179. Purt. ! 31 SS. Fez. Ccrasi.

On dead branches of the wild cherry-tree. Connnon. I find a form 

 very much resembling /3. Padi on the common Laurel. 



2. C. Prundstri, Vor^. (Plum-tree Crnanr/iutii) ,- subc.Tspitoso, 

 of a somewhat horny cousisilence naked blackish, cup at first 

 awl-shaped, at length ojjen concave substipitate. Fr. Syst,

On branches o{ Pruiius spi/iosa, &c. Autumn and winter. — Burst- 

 ing throngh thel):irk,in the guise of awl-shaped bodies, which gradually 

 become di[)rcsseil in the centre and at length expanilcil into a cup. 

 This is not however [)eculiar to the present species, as Cenangium 

 Ctrasi sometin)es puts on the same form. Indeeil, some true Peziza,' 

 as P. liuccina, P. tu/ftrosa, «*\:c , wlien )oung have a somewhat similar 

 aspect. Cenangium Itdus, another species allied to this an<l the fore- 

 going, has been ailiiiilted into the list of British Fiuigi by Mr. Purfcn ; 

 but his s[)ecimcn3, on dissection, prove to belong to Sj)/it(ria S'fnt- 

 iiulla.
