 spores. 



Scutularia citrina. Sacc, SylL, viii. n. 3317. (figs. 

 21-26, p. 91.) 



Ascophore sessile, plane, rather fleshy, smooth and even, 

 circular disc lemon-colour, externally paler, ^-f mm. across ; 

 excipulum parenchymatous, cells 9-12 ^ diameter; asci nar- 

 rowly cylindric-clavate, apex narrowed, pedicel often crooked, 

 8-spored; spores arranged in a parallel fascicle, hyaline, 

 needle-shaped, ends pointed, multi-septate, 80-100 x 1 • 5-2 /a ; 

 paraphyses very slender, hyaline. 



Patellaria citrina, B. & Br., Ann. Nat. Hist., n. 583 ; Ser. ii. 

 vol. vii. p. 17 ; Phil., Brit. Disc, p. 370. 



Ascdbolus citrinus, Cheval., PI. En. Par., i. t. 31. 



On rose twigs lying in a running stream. 



Berkeley's specimen examined. 



Our plant answers exactly in outward appearance to that 

 of Chevallier, having a broad, flat, yellow hymenium, with a 

 pale border. The asci are clavate, and contain long filiform 

 sporidia. We suspect these are what Chevallier calls asci, 

 considering the included granules as sporidia. (B. & Br.) 



Scutularia vermifera. Sacc, Syll., viii. n. 3310. 



Scattered, sessile, cupulate then patellate, black, glabrous, 

 margin entire, about ^ mm. broad ; asci broadly clavate, 

 8-spored ; spores narrowly cylindrical, worm-like, multi-gut- 

 tulate, 30-35 x 3 /n; paraphyses slenderly filiform, abundant, 

 branched. 



Patellaria vermifera, PhU., Brit, Disc, p. 369. 



On dead branches of decorticated holly. 



Specimen not examined. 



Scutularia littoralis. Sacc, SylL, viii. n. 3311. 

 Scattered or crowded, |-f mm. across; externally black 

 and granular, disc fuliginous-brown, concave, margin in- 

 curved, serrated ; asci cylindric-clavate, 8-spored ; spores 

 linear-fusiform, 3-6-guttulate, straight or slightly curved, 

 25 X 2 /x ; paraphyses filiform, slender.
