642. S. (Caulicolse) Ogilviensis, n. s. Tecta ; peritheciis de- 

 pressis ; ostiolo papillseformi ; ascis clavatis ; sporidiis fusiformi- 

 bus bipartite, endochromatibus in quoque loculo tribus. On 

 dead stems of Senecio Jacubcea, Dundee, Mr. W. M. Ogilvie. 



Perithecia scattered, covered by the cuticle, depressed, with a 

 decided obtuse, papillfeform ostiolum. Asci clavate; sporidia 

 biseriate, fusiform, consisting of two apposed cones, the sides of 

 which are slightly hollowed out ; each division containing three 

 endochromes. 



Xo species can be confounded with this when the fructifica- 

 tion is properly observed. Externally it resembles S. herbarum. 



Plate XI. fig. 28. a, b. Sporidia more or less magnified. 



643. S. (Caulieolse) Clivcnsis, n. s. Tecta subglobosa ostiolo 

 minuto perforante; ascis elongato-clavatis ; sporidiis oblongis 

 curvulis utrinque obtusis triseptatis fuscis. On dead stems of 

 some herbaceous plant, apparently Pastinaca sativa, in an old 

 stone pit at King's Cliffe, July 1850. It will probably prove 

 common, but the name is intended to indicate the place where it 

 first occurred. Entirely covered, with the exception of the 

 minute ostiolum which penetrates the cuticle. 



Perithecia subglobose. Asci clavate, elongated ; sporidia 

 biseriate, oblong, slightly curved, very obtuse, triseptate ; some- 

 times constricted at the articulations, dark brown. 



Allied to S. herbarum, but with very different sporidia. We 

 can find no indication, in authors, of this species, whose fruit is 

 extremely beautiful. 



Plate XI. fig. 29. a. Ascus ; b. sporidia more or less magnified. 



644. S. (Caulieola?) modesta, Desm. PI. Crypt, no. 1786. On 

 dead stems of Scrophularia, Glen Isla, Mr. W. Gardiner, May 

 1816 (no. 131). 



M. Desmazieres' specimens are on Scabiosa. The peculiar 

 character is the swelling out of the third joint of the curved, 

 multispptate, subfusiform sporidia. In S. complanata the spo- 

 ridia are larger, with the second joint swollen, as in Libert, no. 

 244. &. complanata, Desm. no. 713, appears exactly intermediate 

 between the two ; in this we find the third joint swollen. In 

 both, the asci are cylindrical, but they are clavate in £. modesta. 

 In Fries' l Scl. Succ' we find in one copy Phacidium Patella, and 

 in another which exactly resembles Madame Libert's plant ex- 

 ternally, there are no asci, but slender fusiform spores, seated on 

 sporophorcs, which must either be considered as a Septoria, or 

 as the Sphseropsoid form of the species. 



The swollen joint in this and several other species may
