881. S. (Platystomse) angustilahra, n. s. Peritheciis semi- 

 immersis rugulosis ; ostiolo angusto compresso ; sporidiis fusi- 

 formibus appencliculatis curvatis uniseptatis 4-6-nucleatis. 



On gorse. Leicestershire, Rev. A. Bloxam. 



Perithecia half-immersed, rugulose, somewhat elongated; os- 

 tiolum compressed, narrow; asci clavate; sporidia biseriate, 

 •0018-"0016 inch long, fusiform, curved, uniseptate, constricted 

 at the septum, each articulation containing from two to three 

 nuclei, and terminating in a hyaline point. 



Differing from S. excipuliformis in the structure of the spores, 

 which are possibly at length multiseptate ; but, if so, they are at 

 first composed of two very elongated cones ajiposed to each 

 other at their bases, and strongly constricted at the commissure.

*;Sf. (Platystomoe) mncrostoma, Tode, Fung. ]\Ieck. f. 7Q, 77. 

 On dead holly twigs. Spye Park, April 19, 1850, C. E. B. 



Sporidia '0008 inch long, oblong, torulose, triseptate. Very 

 like those of S. Aspegrenii. 



88.2. ^. (Ceratostomse) lampadophura, n. s. Peritheciis gre- 

 gariis globosis sordide pruinosis, coUo longo flexuoso irregulari ; 

 sporidiis fusiformibus curvis multiseptatis. 



On decayed wood. Batheaston, Oct. 1855 ; Combe Hay, 

 April 1855, C. E. B. 



Gregarious; perithecia middle-sized, globose, brownish, pul- 

 verulent or subtomentose ; neck elongated, irregular, Hexuous ; 

 sporidia lineari-fusiform, 'OOS inch long, multiseptate. 



A very fine species, with the habit of S. rostrata ; but that 

 has minute sausage-shaped sporidia.

883. S. (Ceratostomre) ligneola, n. s. Peritheciis globosis 

 subglaucis glabris demersis, collo elongato obtuso; sporidiis 

 ellipticis uniseptatis. 



On decayed oak. Portbury, Somerset, Jan. 1815, C. E. B. 



Perithecia scattered, immersed in the wood, globose, smooth, 

 black with a slight glaucous bloom ; neck about as long as the 

 perithecia, obtuse; sporidia •0003-'0004' inch long, binucleate, 

 at length uniseptate. 



Resembling young S. cirrhosa, but perfectly smooth and glau- 

 cous, and by no means fibrillose.

884. S. (Obtectse) Glis, Berk. & Curr. Peritheciis mediis 

 depressis sub epidermide nidulantibus astomis ; mycelio amplo 

 tomentoso fusco ; sporidiis oblongis curvis obtusissimis quadri- 

 nucleatis.
