Hab. Conception ; on the dead leaves of Quadria heterophylla. — This curious plant, of a yellow colour, 

 sometimes tinged with green, covers old leaves of the Quadria ( Gevuia avellana, Mol.) with dense csespi- 

 tose but radiated jointless filaments. Fructifications are frequent on the upper sides of the prostrate lateral 

 filaments. — We must confess that we are doubtful respecting- the genus.

 1. DOTHIDEA. Fries. 



1. D. granulosa; nuda suborbicularis planiuscula atra opaca rugosa intus concolor, 

 cellulis immersis, ostiolis minutis numerosissimis prominulis granuliformibus. 



Hab. Valparaiso ; on the lower side of the leaves of Eugenia Temu. — This little plant forms irregular 

 black spots on the epidermis, and has a near affinity with the Dothidea of the Betula nana, in Europe : but 

 there the surface is shining - , the cells are white, and the ostiola are larger and more prominent. 



The following additional species appear to have been detected by the Expedition on its return to Chili, 

 probably at Valparaiso, and were placed in the same packet with the Mexican Collection : on which account 

 they were previously overlooked by us.

 is called Boigue in Chili.

 brevissime petiolatis basi vix attenuatis rigidis spinoso-dentatis mucronatis junioribus integerrimis, pedunculis 

 4^5 subumbellatis, foliis brevioribus subcernuis, germinibus ovatis apice vix attenuatis. Mart, in Schult. Syst. 

 Veget. v. l.p. 12. — Hab. Valparaiso. — This plant we have lately received from Messrs. Bridges and Mathews 

 from the same country ; and from Mr. Macrae, gathered at the Baths of Collina.
