Stcrcocaulon coralloidcs is a common species in many parts of our 

 countr}'. It is more a lowland species than S.pasc/iair and S. toinciitosuiii; 

 I have seen no specimens from alpine, and few from subalpine stations. 



In Western Norway it is to a large extent replaced by S. cvohitimi 

 on the coast, but at the inland end of the fjords S. coralloidcs is the more 

 common species. S. coralloidcs is rare in Northern Norwa}'. The plants 

 from Nordland and Tromsø were determined by Th. Fries, but Norman's 

 plants from Forset are not typical. 



S. coralloidcs is a variable species. Very noteworthy is var. cotiglo- 

 incratnm Th. Fr. Lieh. Scand p. 44 = S. paschalc var. siihcoralliiioidcs Nyl. 

 Scand. p. 64, and later treated as a proper species by Nylander as well 

 as by Wainio. The best description is Wainio's in Lieh. Vib. p. 43: 

 Todetia extus hydrate kalico lutescentia, medulla kalico immutata; apothecia 

 pileata, tamen primo plana, saepissime demum majuscula. Saepe etiam 

 minor est quam Ster. coralloidcs, caespites magis congestos et ramosos 

 formans'. . . . 'facile a Stcr. coralloidc diagnoscitur, cujus apothecia minuta 

 et mox convexa, medulla hydrate kalico demum lutescens vel desiccata 

 demum fulvescens, ramuli phyllocladiorum saepissime majores et crassiores.' 



\n the type the positive reaction with KOH is intense. Lang distri- 

 buted Finnish specimens of ^Stercocanlon stiôcoralloidcs' in the Krypt. Vind. 

 2066, the medullary reaction is 'KOH dilute, sed distincte flavescens.' — 



The Norw. specimens here referred to var. congloiiicratuni, were at 

 first 'medulla KOH -4-' or 'dilutissime flavescens', but after some time a
