The thallus agrees more with war. paiiiiiforinis than with the type. 

 The laciniae are thin and narrow. The spores are thick-walled and of a 

 great variability as to size, as usu2A w'lih. P. oniplialodcs: 14 — 23x8 — 12 [x;

I have only seen sterile specimens from Norway. 



A rare plant in our country, recorded only from a few stations, espe- 

 ciallv from the continental lowlands. 



39. Parmelia oUvaria Hue. 



Only recorded from a few stations in Norway: 'Gudbrandsdalen' (Moe), 

 ■"Inter Oien et Kievstad' — also in Gudbrandsdalen — (Th. Fr.), and 'Vig' 

 (Kindt). 



The Norwegian specimens are sterile. The pycnides were ver}- rare, 

 all of them sterile. 



According to Th. Fr. Scand. p. 112 Parmelia pcrlata Ach. is a mix- 

 tum of several species, now recognized as distinct. 'Sub nomine P. pcrlata 

 ß. olivetoruni Univ. p. 458, Syn. p. 198 [P. pcrlatae ß. olivariae Meth. p. 

 217) unicum adest specimen, quod Ca CI nullo modo afficitur, sed K et 

 intus flavescit (minus pure) et extus fuscescenti- lutescit.' Accordingly P. 

 ■olivaria Hue is not identical with P. pcrlata ß. olivaria Ach. I have, how- 

 ever, retained the name of Hue on the reason that it is well known and 

 understood.
