2616. Sphoerla dloica. Moug. " Two-ranked Sphaeria." 



Scattered or subgregarious, semi-immersed, the matrix 

 blackened ; perithecia black, rough, often sulcate above, sub- 

 conical ; asci clavate, stipitate ; sporidia crowded or biseriate, 

 narrowly elliptical, obtuse, triseptate scarcely constricted, pale

The asci are always clavate. Sporidia ('0006 in.) 



Mr. Currey states that the specimens of S. dioica in the Hookerian collec- 

 tion are only a sub-cuticular form of S. pulvis-pyrius. The specimens on 

 furze, which are here referred to S. dioica, are quite different from S. pulvis- 

 pyrius, the perithecia are much larger, less densely gregarious, different in 

 shape, and with distinctly clavate asci.

Cfespitose, superficially innate ; perithecia crowded, globose, 

 papillate, black, very minute, punctato-rugose. — Sow. t. 394, /.

"I believe this production to be a Verrucaria. The contents of the peri- 

 thecia are grumous, containing biseriate fusiform sporidia."— J/. J".^. Spori- 

 dia reddish-brown, opaque, lageniform, when young with a gelatinous en- 

 velope, the tips of the sporidia are paler than the body, they are irregular 

 in length and breadth, varying from ■UO16-'O028 in. in length. There is 

 Bome doubt whether this plant be not a Verrv/:aria. — F.C. 



2619. Sphaexia juglandia. Fr. " Walnut Spbseria."
