phis astrea, Tuck. in litt, & in Nyl. Enum. Gen., 
Suppl. Upon Holly, Elm, Maple, and Bald Cypress, P 
in the low country of South Carolina; Mr. Ravenel. | 
On various barks, in Cuba; Mr. Wright. In one of 
the Cuba forms the apothecia are curiously rounded, 
suggesting a comparison with Acoliwm leucampyaz : 
(Trachylia, Tuck. Obs. Lich., & in Wright Lich. Cub. 
n. 21.) This state passes into an elongated one which 
is sometimes, as it were, torulose, the apothecium ap- 
pearing to break up into smaller ones, as in many 
tropical Bialore (apoth. proliferis.) Thece abundant 
in all the forms, but the spores very rarely perfected 
in the extraordinary Carolina one distinguished as 0, 
and I consider this a less typical state. It has much 
of the aspect of Graphis Afzelit.

Mountains. Illinois, Mr. Hall. Spores taking a 
claret colour, at length violet, with iodine. The di» 
versity in the spores from @. scripta, is corroborated a 
by the remarkably dilated, stroma-like, accessory ex- 
ciple, which is comparable with the accessory margin 
of Opegrapha herpetica v. subocellata, but more pro- sd 
nounced; and sufficiently indicates the lichen to the 
naked eye.
