Nordiia(;kn IjrDught home a very remarkable Cyrophara from Xeclalen, 

 near Sylene. 



Its habitus approaches to C. polyrrhiza. It is medium-sized (3 cm. I, 

 monophyllous, but incise, crisp, affixed at the centre with free margins, coria- 

 ceous and rigid, upper side divided in compartments by black crenate fur- 

 rows, each compartment areolately -rugose, colour whitish-grey. Lower side 

 black, minutely scabrous, almost naked at the centre and rhizinose towards 

 the margi/i. Rhizinae long, black or slightly decolorated, undivided or 

 (rarely) furcate. 



Perhaps a new species, related to G. vcllea or G. polyrrliiza, but only 

 one sterile specimen seen.

Gyrophora Jiirsuta is a nitrophilous species, common or perhaps even 

 frequent in the Eastern lowlands along waysides, at the lower part of sub- 

 alpine rocks^ and the like. Evidently common in Western Norway, cer- 

 tainly less common in Northern Norw^ay, but well developed as far north 

 as Alten. It is rather rare above the upper forest line, but it occasionally 

 ascends to considerable altitudes (at Finse at least to 1450 m.). 



There is no typical specimen of Gyrophora grisea (= G. nutriiia) seen 

 from Norway. A few specimens approach to it, but they are evidentl}^ 

 young G. hirsuta with poorly developed rhizinae. 



I have measured broader spores than Harmaxd (Lieh. France p. 697 : 

 9—12X5—6) : 8—11x5,5—8.
