Somewhat resembles a small Fuciis, and has been placed by autboi-s in 

 different ^euera, though by some regarded as a proper oenus. The typically 

 depressed or subdepressed th alius, as observed by Ny lander /. c, and the 

 nature of the spermogones, induce us to refer it to Panneha. near P. hi- 

 nata, to which in various respects it has a marked affinity. The thallus 

 is closely and uuibilicately affixed to the substratum, over which it occa- 

 sionally spreads in large patches, though usually it occurs in small and 

 scattered tufts. The apothecia, which are common, are subterminal on 

 short deflexed ramules ; the spermogones are numerous, prominent, with 

 .'■permatia 0,00-5 mm. long, 0,001 mm. thick.

Readily recognized by the naked under surface and the more or less 

 inflated apices of the laciniae. The thallus is nomiaUy orbicular, but at 

 length becomes expanded, vaniug considerably in the character of 

 the lacinife, and thus presenting several forms and varieties. The apo- 

 thecia are not frequent in Britain ; they are iirceolate, and small when 

 young, at length large, plane and flexuose. The spermogones are very
