615. Spharia (Circinatse) hapalocystis, n. s. Sparsa tecta; 

 peritheciis subglobosis tenuibus subtiliter tomentosis, collo ob- 

 lique deorsum constricto una cum ostiolo breviter fusiformi; 

 sporidiis oblongo-ellipticis utrinque appendiculatis biseptatis. 

 On dead twigs of plane, Batheaston. 



This species, which is just intermediate between Obtectce and 

 Circinatcey is closely allied to S. aucta, but differs in the nature 

 of the spores, which are broader in proportion, especially when 

 old, and are essentially biseptate, whereas in S. aucta they are 

 uniseptate or triseptate from the division of the two original 

 endochromes. In both there is the same peculiar truncate hya- 

 line appendage. The perithecia are peculiarly delicate. There 

 is some resemblance also to S. vestita, but the perithecia are 

 more decidedly tomentose in that species.

Forming orbicular sori beneath the true cuticle about a line 

 broad. Perithecia at length exposed, subglobose, with an obtuse 

 papillseform ostiolum beset with stiff dark bristles as long or 

 longer than themselves, springing from a radiating more or less 

 interwoven stratum of very obscurely septate brownish threads, 

 amongst which are a few darker and closely articulate. Asci 

 short, subcylindrical, obtuse ; sporidia oblong, short, containing 

 about four nuclei or four regular endochromes, or more properly 

 uniseptate with two endochromes in each division. 



This has precisely the habit of Lasiobotrt/s, and occurring on
