As it is the case with many 'petites espèces' among the foliaceous lichens, 

 PanncUa fnbiilosa was entirely neglected b}' former investigators in our 

 country, and its accurate distribution is, therefore, insufficiendy known. 



Parnirlia /iiùidosa is common in the south-eastern and southern low- 

 land and in subalpine positions, in Western Norway it is also common 

 in the fjords and — according to Havaas — a little less common on the 

 coast. Its distribution in the Trondhjem (Drontheim) and Nordland districts 

 is little known. There are only two stations known north of Lofoten; I 

 could not find it in the valleys of Troms fylke. Most probably it belongs 

 to those species which have a continuous distribution as far north as Lo- 

 foten, but which only occasionally pass this barrier against arctic climate. 



— The specimen from Tormsø is large and well de\'eloped. 



Its vertical distribution is less known. I have never seen it above the 

 tree line, and it is more common in lowland than in subalpine positions. 



— In Western Norw^a}^ it ascends to 7 — 800 m. (Havaas). 



It is often associated with Pannclia physodcs, but always well sepa- 

 rated from this species. It prefers the twigs and stems of Conifers {Pinus 

 and Picea), and of Betiila verrucosa and odorafa, which show great simi- 

 larity to the Conifers with respect to their lichen vegejiation. It is also 

 frequenth' found on wood palings and roofs. I have only once observed 

 it on rocks, Swedish and German authors (Magnusson, Bitter, Sandstede) 

 also found it on rocks, and on sand.
