AscoPHORE. — Eriimpent, cjespitose ; perlthecla snbglobose, 

 papillate, bursting- through elongated fissures in the bark, black ; 

 asci elongated, cylindrical ; sporidia nniscriate, elliptic, imisep- 

 tate, brown. — Cooke Seem. /owrn. (1866), iv. t. 45,/. 7. Didymo-

 Sometimes the perithecia are arranged in short lines, 



2678. Spheezia appendiculosa. B.&Br. " Appendiculate 



Spha3ria." 



Perithecia scattered, globose, nestling under the blackened 

 epidermis in small orbicular polished spots, pierced in the centre ; 

 sporidia ovate-lanceolate, appendiculate. — B. ^ Br. Ann. N,H. no. 

 613, t. 7,/. 20. Caltt. Linn. Trans, xxii. t. 58,/. 97. 



On dead bramble. 



Perithecia globo?e, scattered, nestling under small orbicular, blacl^^ shining 

 specks, and penetrating them by the ostiolum, round which there is often a 

 little white meal ; sporidia ovato-lanceolate, at first hyaline with an apicu- 

 late process which gradually separates by a constriction, and ultimately falls 

 off. Resembling closely S. tovimcm, Lev. but differing materially in the much 

 larger and more highly developed sporidia. — B. d: Br. Sporidia ("001 in.) •025 

 m.m. with the appendage. 





Sporidia coloured, with 3, or more septa. 



2679. Sphsezia fuscella. B. 4^ Br. " Brown Rose Sphseria." 



Scattered, covered ; perithecia brown, depressed ; asci linear, 

 obtuse ; sporidia uniseriate, oblong-elliptic, sometimes slightly 

 curved, triseptate. — B. 4^ Br. Ann. N.H. no. 636, t. 11,/. 20.

On dead twigs of rose. March. Easton. 



Scattered, forming minute pustules ; perithecia depressed, subglobose. 

 brown ; asci linear, containing eight sporidia in a single row ; sporidia pale 

 brown, oblong-elliptic, obtuse, triseptate, by no means constricted at the 

 articulation, sometimes slightly curved. Distinguished from S. sepincola by 

 its minute brown perithecia, and even elliptic obtuse sporidia. There is no 

 sign of ostiolum externally. — B. ct* Br. Sporidia ("0007 in.) '0177 m.m. long. 



2680. Sphseria unicaudata. B. 4- Br. «* One-tailed Sphaeria." 



Perithecia minute, covered, subglobose, collapsing ; sporidia 

 clavate, quadriseptate, caudate. — B. ^' Br. Ann. N.H. no. 886, t.
