iDlackisli ascophore ; the narrow, long and slenderly stipitate 

 asci, and the brown, continuous, oblique spores, four of which 

 are only usually present in an ascus,

 1886, p. 595 ; Eehm, Krypt.-Plora, Disc, p. 495, figs, 1-5, 

 p. 472. 



Ascophores gregarious or caespitose, erumpent, at first 

 more or less clavate, closed, rusty-brown, and scurfy, the disc 

 gradually expanding and becoming plane or slightly convex, 

 black and shining, externally umber-brown, wrinkled and 

 scurfy, turbinate and narrowed into a short, stout, stem-like 

 base, which is mostly buried in the substance of the host, 

 1^4 cm. across, and the same in height ; gelatinous, flesh 

 brown ; asci cylindric-clavate, narrowed below into a long, 

 slender base, usually only containing four perfectly developed 

 spores ; spores 1-seriate, continuous, elliptical, usually slightly 

 curved, 1-2-guttulate, brown at maturity, 10-14 x 5-6 /x; 

 paraphyses slender, slightly thickened, brownish, and more 

 or less curved at the tips.

On dead trunks of trees, especially beech. 



The fungus bursts through the bark under the form of 

 small rusty-brown, scurfy knobs, which gradually expand at 

 the apex until a plane, black, shining disc is formed. Sub- 

 stance soft and tough, cutting almost like india-rubber. 



According to Fuckel — Symb. Myc, p. 286 — Tretnella 

 foliacea (JJlocolla foliaceae, Bref., Brit. Fung.-Flora, vol. i. 

 p. 60), is the conidial condition of the present species. 



BULGAEIELLA. Karsten. (figs. 8-10, p. 156.) 



Ascophore subgelatinous, sessile, discoid, attached by a 

 central point, glabrous, disc plane or convex, open from the 

 earliest stage; black; excipulum composed of interwoven 

 hyphae ; asoi cylindrical, 8-spored ; spores 1-seriate, ellip- 

 tical, coloured ; paraphyses present.
