 Thwaites, Esq.) 



Spots f an inch or more broad, dingy; peridia scattered, more nu- 

 merous towards the centre ; border reflexed, lobed. Cells not crenate

Graphiola PAcenicis, Poiteau. 



Hab. On Phoenix farinif era. Ceylon. (Gr. H. K. Thwaites, Esq.) 



496. Spheria (Csespitosse) Broomeiana^ tl, s. ; peritheciis in csespi- 

 tem orbicularem congestis atris opacis satis brevibus exasperatis; 

 ostiolo papillEeformi notatis vel omnino astomis ; ascis clavatis latis ; 



sporidiis innumeris minutis oblongis curvis. 



Hab. On dead wood, Ceylon. (G, H. K. Thwaites, Esq.) 

 Perithecia black, opake, sprinkled with short, black, stout bristles, 

 crowded into little orbicular tufts, scarce a line broad, either altogether 

 destitute of an ostiolum or with ah abrupt central papilla. Asci clavate, 

 broad, stuffed with numerous, oblong, curved, minute, hyaline sporidia. 

 The minutely setulose perithecia, and abundant sporidia, at once 

 distinguish this species from any with which it might be confounded.

A form of Sjphceria rejpem, Corda, with shorter asci, less shining pus- 

 tules, and more orbicular sporidia.
