On leaves of Musacea. East Indies. Dr. Wight. Cells 

 arranged in lines, following the nervation of the leaf. 



3. D. (Asteroma) conspurcata, Berk. Flat, membranous, 

 uniform, orbicular, dull pitch-brown ; perithecia few, scattered, 

 hemispherical, of the same colour. Forming small brown 

 spots on the under and upper side of the leaf, exactly like fly- 

 specks. The margin though irregular is not the least fimbri- 

 ate, or it would more properly be placed in the genus Aste- 

 roma. 



On the leaves of a myrtle called Luma, in hilly woods. Juan 

 Fernandez. Bertero. May, 1830. No. 1728. Not in Mont. 

 Fl. Fern.

 Kunth. Syn. vol. i. p. 7. Scattered, orbicular, depressed, 

 opening with 5 — 6 black acute lacinice ; disk black, at length 

 naked, bordered by the excipulum. About the size of P. co- 

 ronatum. Asci short, linear, obtuse. I do not find curved 

 paraphyses as in that species.

1. Geaster plicatus, Berk. Geaster striatus,y plicatus,K\. 

 Mss. in Hook. Herb. Outer peridium soft, papyraceous, pale 

 umber, smooth ; laciniae about 7> acute ; inner peridium seated 

 on a long peduncle, globose, dark umber, smooth, strongly 

 plicate at the base ; orifice seated in a circular depression, co- 

 nical, plicato-sulcate. Sporidia brown. 



Madras. Dr. Wight. Nearly allied to G. striatus, /3. mi- 

 nimus, but certainly distinct. The folds at the base of the 

 inner peridium are very remarkable.
