Central and abundant on all rocky coasts from the Swedish frontier 

 in South to Lofoten in north. It is most probably rare north of Lofoten, 

 only recorded from a ïew stations. 



If tested with KOH the cortex in most cases takes a reddish colour, at 

 least after some time. The medulla is generally insensible to KOH (/?. 

 Citspidata Xyl. I. In some specimens the medulla is after some time coloured 

 vellow or even reddish, occasionally this is seen as soon as the solution 

 is dried up. (Diftusion from the cortex?). A distinct red colour is ver}- 

 rarely seen in Norwegian specimens. (R. scopiilorwn sensu Nyl.I. In 

 Norway quite typical R. scopulonim Nyl. has onl}- been recorded from a few 

 stations on the west coast. — I can see no morphological difterence between 

 R. scopiilontm Nyl. and R. cusp/da fa Nyl. I am unable to distinguish be- 

 tween these two 'species', and I look upon the R. ciispidata only as a form 

 of R. scopii/onmi. R. Ciin/oa'ii is nearly related; its base is darker and its 

 podetia more slender.

It is probable that this species is more common than the above stations 

 will indicate, at least on our west coast.
