ab Italia & Hispania Dufourl — ad Nordlandi- 



am usque IVahlenberg ! 



JEximie orbicularis , sed plures subinde confluunt. 

 Hypothallus determinatus & integer a matre secedens, ex- 

 tra ambitum thalli prominens obtusus. Apothecia fere 

 Biatorae (aut potius Stictoe) ob excipulum coioratum , sed 

 discus crassus primo inclusus ; subtus observatur stratum 

 gonimon. — b. vetustissima, nullo modo transitum ad 

 sequentem offert. In hac & sequente luculentissime vidi 

 apoth. symphycarpea a pluribus coalitis orta esse.

Loco & patria cum priori convenit, optima

Rotundata aut effusa. Hypothallus indeterminatus, 

 tenuior ? arcte adnatus , haud integer a matre secedens. 

 Apothecia jam primitus a thallo erumpentia crenulato 

 margine cincta. A priori certe distincta!, licet affinis; 

 utraque nobis frequenter obvia. Sed infimae ejus proles 

 a Parm. triptophyllae rite discerni nequeunt; at quse 

 species ejusdem seriei non conjungendae ex infimis proli-
