Cladoiiin squamosa is a very trequent species in Southern Norway, in 

 the forest {Piiiiis and Picea), in Ericcta, on moorlands, on sunny rocks on 

 the coast, and on old stumps and mossy rocks. It ascends somewhat 

 higher than the tree line. — It is not so common northwards. Nordland 

 has been poorly investigated; it is not rare in Troms and Western Fin- 

 mark (Alten), but east of Alten it must be rare. 



Lichens of this frequency usually offer many 'formae' or 'varietates' 

 but it is rather extraordinary to find such a series of 'formae viliores'. 

 There are hardly any two formae so distinct that intermediate stages can- 

 not be found. I must, therefore, look upon the whole complex of formae 

 as types of variation, very interesting as such, but not as distinct syste- 

 .matic units. 



The types here mentioned may be thus arranged: ' 

 I. Podetia scyphous. 



2. Podetia very short (5 — 10 mm.), f. piiyrea Arn. 

 2*. Podetia lonirer.
