Par//ie/ia aspidota prefers the bark of deciduous trees, especially A///us, 

 but also F/-axi//its, Bcf/i/a, and others. In Northern Norway and in sub- 

 alpine regions it is occasional!}- found on rocks (marked with an asterisc). 



Pa/-/iic/ia aspidota is distributed throughout our whole country, 'in pro- 

 vinciis maxime hyperboreis tamen rarescit' (Th. Fr. Lieh. Scand. p. 122 1. It 

 is a faithful companion of A////is i//ca//a and is frequent as far north as this 

 tree is, i. e. to Alten in Western Finmark. In Interior Finmark and at the 

 eastern Finmark tlords it is certainly rare though not missing, no stations from 

 the Arctic coast east of Hammerfest. Its accurate distribution in Southern 

 Norway is not quite clear. It is common in the lowlands, in the region 

 of the warmth-loving deciduous trees; it is perhaps less common along the 

 coast, and not common or rare in subalpine regions. I have not seen it 

 from stations higher than 700 m. s. m. (Drivstuen).
