by its gyrose apothecia. These large plants might be regarded as a proper 

 species, but there are transitional stages to the type of G. cy/i/idriai. It is 

 a northern plant. G.cyliiidrica from Ellesmereland (Second Arc. Exp. Fram, 

 Lichens, p. 241 is f. Delisci). 



f. Delisci is no common plant in Norway, but like many alpine plants 

 it usually occurs in great numbers. It is recorded from very high moun- 

 tains in Southern Norway, in Northern Norway it descends to the level 

 of the sea.

Sortr. 'Dovre'? (Moe). 



One of the most frequent lichens on the south coast, it covers exten- 

 sive areas on maritime rocks. Less common on the west coast, no speci- 

 mens recorded north of Stat. Common on the western mountains (ace, to 

 Havaas), a rare species in eastern inland subalpine and alpine districts. 

 Cfr. G. cnisfitlosa: 'Gyrophora spodochroa from Dovre in hb. Ups., an O'li- 

 stiilosa ? 



The development of the fibrillae is variable in the cirrhosa-sccixon, as 

 with several other Gyrophorae. Nylander attributed a specific name [tylo- 

 rhiza) to plants of this section if the fibrillae were transformed into Verrucae. 

 I have seen 'tylorhiza' plants of G. cirrhosa as well as of G. vcHca, and I 

 agree with Th.M. Fries: 'tylorhiza est forma omnino accidentalis neque 

 species propria' (Lieh. Scand. p. 253).
