Remark on Haematostagon balanicola Stromf. 



In M. F osi le 



In «( New or criticai Norwciiian Alga: » ') I referrcd to PcyssoncWa 

 Roscnviugii Schm. ) an alga, that I met with at Lyngò ncar 

 Tromsò. At the same timo I idcntiiìed the former with Ilicnialcstagon 

 bdhiniccla Stromf. '\ and consequently 1 named it l\-yssoNciIia

 plant from Lyngò. but as this has not been the case and I bave 

 but little occasion later to get it 1 want, thereforc. to make some 

 comments on this matter. 



I found my specimens. although sterile, so nearly coinciding 

 with the description and ligure by Schmitz 1. e. that. if a steril 

 Squamariacé is not always quitc impossible to determine - an opi- 

 nion, which, though often, cannot in ali cases be granted. - my 

 specimens must be referred to the named species. 1 sent Prof. 

 Schmitz some of my specimens of the named plant from Lyngò, 

 and he kindly sent me a slide of a typical specimen of Pcyssoncllia 

 Rosenvìngii from Greenland for examination. and reuìarked : t Sie 

 werden zwischen dieser Art und Ihrer Alge viel Uebereinstimmung 

 wahrnemen. allein doch nicht voUstiindige Identitàt». At the same 

 time he sent me a slide of a Squamariacé from Scotland. which he 

 also mentions in Nuova Notarisia. and presumed that. perhaps. I
