EPHELINA. 75 



Tulasne describes the occurrence of minute, ovate, con- 

 tinuous, hyaline spermatia about 5 x p-, borne on slender, 

 hyaline sterigmata, and produced in specialised conceptacles 

 in the stroma. Plowright describes similar bodies, and says 

 they are formed in the ascophores previous to the formation 

 of asci. The last-named author describes Grev., vol. iv. 

 p. 28, pi. 53, figs. 1-9 what he considers to be other 

 secondary forms of fruit. A Fusarium which oozes out upon 

 the surface of the stroma in little pink masses ; the spores 

 are curved, obscurely 3-septate at maturity. Secondly, 

 minute perithecia with a minute, black, shining ostiole, 

 seated on the stroma, and containing oblong, smooth, usually 

 3-septate, brown spores; the spores have occasionally 4 

 transverse and 1 vertical septum. 



Specimens examined from Cooke, Fung. Brit., exs., n. 670 ; 

 and Fries, Scler. Suec., n. 250; also Sowerby's specimens 

 figured in English Fungi, pi. 356, as Spliaeria aurea. 



EPHELINA. Sacc. (figs. 28-30, p. 22.) 



Ascophore at first tuberculose then splitting and exposing 

 the disc, somewhat coriaceous, small, gregarious, sessile, 

 springing from a blackish, parenchymatous, effused stroma ; 

 asci cylindrical, 8-spored ; spores continuous, hyaline ; 

 paraphyses slender. 



Ephelina, Sacc., Syll., vol. viii. p. 585. 



Ephelis, Phil., Brit. Disc., p. 358 (not of Fries nor Sacc.) 



The ascophores spring from a distinctly parenchymatous 

 stroma, and amongst British genera the present genus is 

 most closely allied to Ehytisma. 



Ephelina radicalis. Mass. (figs. 28-30, p. 22.) 



Ascophore J 1 mm. across, tuberculose then expanding, 

 rough and blackish externally, disc greyish, sessile, grega- 

 rious on a blackish, distinctly parenchymatous stroina ; asci 

 narrowly cylindrical, spores 8, obliquely 1 -seriate, slightly 

 but distinctly clavate, smooth, hyaline, 10 X 4-5 ^; para- 

 physes slender, slightly thickened at the apex.
