" Perisporium nitiduliim. Nitidnm nigrum in maculas congrega- 

 tum ; peritheciis minutis hemisphericis ; sporidiis subglobosis minu- 

 tis fuscis. Welw. No. 38. On dead leaves of Agave Americana with 

 Nectria sanguinea, Sphajria herbarum, &c., near Situbal. Forming 

 little black patches consisting of numerous shining black hemispheri- 

 cal minute perithecia. Sporidia minute subglobose or broadly sub- 

 cymbiform. I have not seen asci, but in several species these are very 

 soon absorbed and the habit is that of Perisporium. 



" Pho77ia ErythriiKB. Peritheciis ostiolisque prominulis ; sporis 

 oblongo linearibus hyalinis. Welw. No. 46. On dead branches of 

 Erythrina Crista Galli ; Lumiar and elsewhere near Lisbon ; mixed 

 with Sphaeropsis crassipes, scattered. Perithecia prominent raising 

 the epidermis which remains unaltered and piercing it by a rather 

 prominent ostiolum. Spores linear, oblong, one three thousandth of 

 an inch long, one sixth as much thick, sporophores about twice as 

 long delicate. 



" Spkaropsii crassipes, Mont. MSS. Gregaria epidermide tecta ; 

 maculis peritheciorum irregularibus atris centro albis ; sporis oblon- 

 gis ; sporophoris subrobustis. Welw. No. 46. On dead branches of 

 Erythrina Crista Galli ; Lumiar. The perithecia occur in irregular 

 patches extending several inches. The cuticle above each perithe- 

 cium is of a shining black, but white in the centre. Sporophores 

 nearly twice as long as the spores, rather stout ; spores oblong, subel- 

 liptic, one seventeen hundred and fiftieth of an inch long. 



" Sepforia brunneola, Berk. Peritheciis epidermide brunneo tec- 

 tis ; sporophoris rectis; sporis sursum curvatis filiformibus dimidio 

 brevioribus. Welw. No. 46. On dead branches of Erythrina Crista 

 Galli, sparingly ; mixed with Spheeropsis crassipes, Mont. Perithe- 

 cia scattered or arranged two or three together in a line covered with 

 the cuticle, which is raised just above them, and of a dull brown. 

 Spores filiform, curved, about one eight hundred and seventy fifth of 

 an inch long, about twice as long as the filiform straight sporophores. 



" Valsa Welicitchsii. Pustulis parvis circumscriptis ; stromate 

 pallido ; peritheciis globosis immersis albofarctis, collis longiusculis ; 

 ostiolis convexis subpunctiformibus ; ascis tenellis; sporidiis curvulis. 

 Welw. No. 47. On the smooth bark of elms ; Cintra. Pustules 

 scarcely one third of a line broad, elevating the bark ; disk narrow ; 

 stroma pale ; perithecia globose immersed about five in each pustule, 

 sometimes however solitary, neck rather long ; ostiola convex snb- 

 punctiform ; asci short, very delicate, sporidia eight minute oblong 

 curved.
