On the bark of pear-trees. Shrewsbury, W. Phillips, Esq. 



We Avere at first inclined to think this a distinct species, as 

 we found the sporidia much smaller, •0004-*0005 inch long, 

 whereas in S. lecanora we found them "0009 inch ; but later 

 observations proved that they are sometimes quite as large, 

 and we therefore consider it a mere variety,

On a piece of cord. Glasnevin Botanic Garden, W. Keit. 



Perithecia rather large, the apex rose-coloured, with a puncti- 

 form impressed ostiolum, and radiated, apparently from the 

 shrinking of the outer coat as they increase in size. Sporidia 

 fusiform, triseptate, constricted at the division, each of which 

 contains a large nucleus, '0012 inch long, '00025 wide. 



It is possible that this very curious species may be of exotic 

 origin, as it occurred in a hothouse. The only species to which 

 it seems to bear any evident relation is S. rhodosticta^ B. & Br., 

 Fungi of Ceylon, no. 1096.

 in A. htUatus they are '0004 inch.
