A rare species in our country, as yet only recorded from a few stations 

 in Southern Norway (on Piiiiis Sylvester). 



The laciniae are narrow, repeatedly dichotomously branched (as in the 

 cerafea), the white soredia well developed, also at the lower side of the 

 thallus. In most specimens the isidia are very reduced, often only short 

 dark papillae. Our specimens agree perfectly with Bitters plate XI, fig. 



43—45- 



There were a few pycnides at the margin of the apothecia, all of them 



sterile. 



Apothecia rarissima. Diam. in specimine usque 8 mm. Apothecia 

 pedicellata, cupuliformia vel concava, receptaculum rugosum, margo tenuis,

 terior crassior et melius evolutus, usque 50 [x crassus. Medulla arachnoidea, 

 hyphae adspersae, tenues, 3 — 4 [x. Gonidia subglomerata, infra cortices
