94 BERNT LYNGE. M.-N. Kl. 



Odnesberget in the parish Land (NORMAN), Vaage (LYNGE), Finse (LYNGE), 

 Northern : SalFdalen (SOMMERFELT), Astejok near Altevand, and Mestervik in 

 Malangen (LYNGE). 



Specimens with dilated laciniae and typical soredia might be confounded 

 with darker states of P. tribacia, from which it is readily distinguished by 

 the medullar reaction. One specimen from Saltdalen is large, quite fertile, 

 and nearly esorediate, it might be mistaken for P. melops. 



MASSALONGO describes some anatomical characters of his Anaptychia 

 stellaris d. dubia (Mem. 1855, p. 37), he found smaller asci than in our 

 Ph. caesia. His figure (tab. VI, fig. 35) is incorrect, giving unseptate 

 paraphyses.
