Kev. M. J. Berkeley and ]Mr. C. E. Broome on British Fungi. 373 



Completely concealed by the cuticle, which shows when re- 

 moved a dense mycelium containing numerous depressed asto- 

 matous perithecia. Sporidia •0008--0009 inch long, sausage- 

 shaped, very obtuse, quadrinucleate. 



Intermediate between S. lanata and S. hirta, the former of 

 which has very large perithecia and minute curved sporidia. 



885. S. (Obtectfe) hemitapha, n. s. Peritheciis globosis semi 

 immersis opacis e macula alba oriundis; ostiolo papillseformi ; 

 sporidiis elliptico-oblongis triseptatis. 



On felled oak. St. Catharine's, Bath, Feb. 1852, C. E. B. 



Growing on white bleached spots; perithecia globose, the 

 upper half free, opake, not shining; ostiolum small, papilli- 

 form; asci lineari-clavate ; sporidia biseriate, 'OOISS inch long, 

 oblong elliptic, at length triseptate, but not torulosc. 



Very near to S. hypotephra, but there are no cinereous spots ; 

 the perithecia are half-exposed, and the sporidia larger.

886. S. (Obtectffi) unicaudata, u. s. Peritheciis minutis sub- 

 tectis subglobosis collabentibus ; sporidiis clavatis quadriscp- 

 tatis deorsum caudatis. 



On Clematis Vitalba. Batheaston, C. E. B. 



Scattered beneath the cuticle, subglobose, collapsed when dry ; 

 asci oblong, but varying in form according to the pressure of 

 the sporidia; sporidia '0015 inch long, clavate, triseptate; the 

 upper articulation hyaline, the three following brownish, often 

 containing a globose nucleus ; appendage, or fifth articulation, 

 hyaline, gradually tapering or constricted near the tip. Very 

 rarely there are four brown articulations. 



A very curious and distinct, though obscure species. The 

 fruit resembles that of S. Massalongi, iMont.

887. S. (Obtectae) ohlitescens, n. s. Peritheciis depressis tec- 

 tis, ostiolo obscuro ; ascis linearibus elougatis ; sporidiis oblongo- 

 ellipticis obtusissimis uniseptatis. 



On dead twigs of Cornus. Spye Park, Jan. 29, 1851. 



Perithecia covered by the cuticle, depressed, moderately large ; 

 asci cylindrical, elongated ; sporidia uniseriate, oblongo-elliptic, 

 very obtuse, uniseptate, slightly constricted at the commissure, 

 •0005 inch long ; paraphyses linear, some of them containing 

 one or two sporidia. 



This species has somewhat the habit of S. mamillana. The 

 cuticle is also occasionally discoloured above the perithecia. 

 The fruit, however, of that species is very different, the sporidia 

 being cymbiform and triseptate.
