973. S. (Denudatae) ordinata, Fr. Syst. ii. p. 454. On de- 

 corticated fallen oak branches. Little Heath, Essex, Dec. 1859. 

 Barking. 



Perithecia scattered or aggregated, arranged in lines, ovate, 

 with a papillary orifice, rusty brown becoming black, covered at 

 first with a tomentose veil, sometimes regularly attenuated, rest- 

 ing on a brownish friable mycelium ; asci clavate ; sporidia bi- 

 seriate, curved, fusiform, hyaline, multiseptate, "0015 inch long, 

 sometimes shorter. 



This appears to be the plant of Fries. Montagne*s plant has 

 elliptic fruit like Spharia milleffrana, "0005 inch long. 



Plate XVII. fig. 26. Ascus and sporidia magnified. 



*S. (Denudatae) pulveracea, Ehrh. Our specimens are exactly 

 the same as S. millegrana, Schwein. 



974. S. (Csespitosse) naucosa, Fr. in Myc. Heft ii. p. 36. 

 On elm. Batheaston, Jan. 1860, C. E. Broome. 



Asci clavate ; sporidia '001 inch long, obovate, multicellular, 

 with vertical and transverse septa. 



We have no typical specimens. The perithecia, when old, 

 are almost black ; the ostiola obsolete ; the surface smooth and 

 shining, with generally a single fissure at the apex.

975. S. (Platystomse) Jerdoni, n. s. Peritheciis sparsis 1. sub- 

 congestis subglobosis, ostiolis angustioribus linearibus ; sporidiis 

 una cum utroque articulo medio constrictis bi- trinucleatis. 



On Rubus Idcms. Mossburnford, A. Jerdon, Esq. East 

 Bergholt, apparently on elm, with the perithecia more scattered, 

 Rev. CD. Badham. 



Perithecia scattered or slightly crowded, subglobose, with 

 narrower linear ostiola ; asci clavate; sporidia biseriate, '0012- 

 •00125 inch long, strongly constricted in the centre, as also each 

 of the two bi- trinucleate joints. 



Plate XVII. fig. 28. Sporidia magnified. 



976. S. (Ceratostomse) stylophora, n. sp. Peritheciis primum 

 tectis demum liberatis in fasciculos orbiculares dispositis ovatis 

 sursum attenuatis ; ostiolis sesquilongioribus ; ascis late clavatis ; 

 sporidiis fusiformibus hyalinis uniseptatis utrinque appendicu- 

 latis. 



On Acer platanoides. Mossburnford, A. Jerdon, Esq. 



At first covered, then exposed ; perithecia collected in little 

 orbicular patches, ovate, attenuated above, with styliform ostiola 

 longer than themselves; asci broadly clavate ; sporidia biseriate, 

 hyaline, fusiform, uniseptate, appendiculate at either end.

 nified.)
