f d'datata and f. dilacerata are \-ery closely related. The dilatata iy- 

 pica (as represented in Malme Lieh. Suec. 564) has esquamose subcN'lin- 

 drical podetia with well developed regular scyphi, the latter f. squamose, 

 more branched, 'and often coarser podetia with oblique, irregular, incise 

 scyphi. There is every transitional stage between them, but they represent 

 two frequent types of variation and in many cases they are quite distinct. 



f. dilatata (incl. f. dilacerata) is a Ibrest plant, common or even frequent 

 in S. E. Norway, present, but less common in Western and Northern Nor- 

 wa\'. It is a lowland plant, less common in subalpine forests, aljiine spe- 

 cimens not seen from Norway. Quite typical f. dilatata is not common, 

 the greater part of our material approaches more or less to f dilacerata. 



They are found on mossy earth and stones in the forest, and at the 

 base of old decayed stumps.
