G. cntstiilosa has been mistaken for G. cirrhosn, and it is as 3'et im- 

 possible to State its accurate distribution in our country. It is evidently 

 chiefly a western species; common on our western coast from Kristianssand 

 to Lofoten. It cannot be so common on our southern coast, and it is cer- 

 tainly rare north of Lofoten. It does not cover large areas like G. cirrhosa, 

 but it has a much wider distribution than the latter species, and it is sup- 

 posed to be more common in alpine inland districts than G. cirrhosa. G. 

 crnstiilosa ascends to very considerable elevations, it has been recorded 

 from the very summit of Lonehorgje (1424 m.), and it has been found at 

 the same elevation at Finse. 



I have found the same chemical reaction for either species : Ca CU O., 

 -^ or almost imperceptibly red, Ca Cl._j O.2 + KOH distincdy red. G. cir- 

 rhosa has slightly longer spores: 18 — 30 x; 11 — 16 (usually not longer than 

 25 [x), G. criistulosa 18 — 24x11 — 16(21) [x, the spores are variable as to 

 size as well as to form in either species. 



The apothecia of G. cntstitlosa are finally prominent, convex, irregu- 

 larly gyrose (almost like the apothecia of G. vcllea). Several specimens 

 have only depressed apothecia with a thick margin and a central papilla 

 and few (if any) concentric gyri (f. depressa Ach.). Intermediate stages are 

 found, and I was unable to find any difference in the spore size. The 

 typical f depressa is not common in Norway. — 



The thallus of G. criistulosa is usually rather rigid and may even 

 approach to G. vcllea in that respect, but quite thin, almost membranaceous 

 thalli are also seen.
