Cetraria hcpatizou is evidently a more alpine species than C. faliliiiwii- 

 sis, otherwise it has the same distribution, but it is more frequent than the 

 latter species. 



There are relatively more stations from Northern than from Southern 

 Norway for these two species. Either of them is also very frequent in 

 Northern Norway. It must, however, be remembered that their distribution 

 in our country was little studied by former investigators (cfr. Th. Fries 

 Lieh. Scand. p. 108I, and that the lichen flora of Northern Norway has been 

 more explored in recent years than that of Southern Norway. 



Cetraria polyschiza Nvl. fl-om 'Fongfjell' (Fongen) is C. faJiliDiciisis. 

 Ace. to Wain. Pitlekai p. 25 the polyschiza is only a f of C. hcpatizou, 

 which is most probable. 



Apothecia \ulgo numerosa, diam. 2 — 5 (81 mm. Discus castaneus, niti- 

 dus, epruinosus, margo crassus grosse crenatus, receptaculum 

 fuscescens, val de pi i ca to - rugosum, interdum subsquamosum, etiam 

 rhizinosum vidimus. Cortices ut in C.fahlitiiciisi. Gonidia sub cortice in- 

 teriori strato continuo disposita, praeterea pauca et dispersa vel omnino 

 carentia. Hypothecium 25 — 45 [x, incoloratum. Hymenium 50 — 80 [j. altum, 

 parte superiore an gus ta flavo-fuscescens, ceterum incoloratum, non insper- 

 sum, strato amorpho incolorato tectum. Paraph y ses cohaerentes, 

 subconstricte septatae, indivisae (vel rarissime ramosae), apice clavato-incras- 

 satae et flavo-fuscescentes. Asci + late clawati, 32 — 50 ;x longi, 10 — 13 [x 

 crassi, membrana apice normaliter incrassata. Sporae optime evolutae, 

 octonae, anguste limbatae, ovales vel late ovales, quam in C. Jahhniciisis 

 majores: 8 — 12 [x longae, 5.2 — 8 jx crassae. 



React. Hypothecium et asci J persistenter caerulescentes, gelatina 

 hymenii J dein sordide flavo-fuscescens, rarius subpersistenter caerulescens. 

 Medulla J vulgo non caerulescens, sed etiam meduUam receptaculi j pro 

 parte vel omnino caerulescentem vidimus. Medulla KOH flavescens.
