■developed in a more southward direction, for inst. L. boreale, L. 

 varians and L. colliculosum. As mentioned above, smaller indi- 

 viduals of the species in question may be confounded with L. 

 varians, but the sporangia are not yet well known in the last 

 named species. On the other hand, as remarked by Kj ell man 

 1. c, it shows some affinity to L. fruticulcsum (L. intermedium 

 Kjellm.). Although they are in general easily distinguished by 

 the external shape, one or the other sometimes assumes forms 

 which in a steril state may be difficult to identify, or easily con- 

 founded. 



Habitat. Along the coast of Finmarken the species generally 

 lives on a depth of 10 — 20 fathom, and here it apparently prefers 

 sandy and shingly bottom. It is found on open shore as well as 

 in sheltered places, and it penetrates rather far up the fjords. Here, 

 I occasionally met with it on a depth of only 3 — 5 fathom. Spe- 

 cimens collected in July and August have partly been sterile partly 

 richly provided with ripe sporangia, or newly emptied conceptacles. 



Occurrence. With us. the species apparently is most com- 

 monly dispersed along the coast of East-Finmarken. Here it has 

 been found at several places, partly even abundant. I met with 

 it at Kjelmo, pretty plentiful but local, Vardo, Mehavn, Kjollefjord, 

 and at Lebesby in Laxefjord, local but abundant. It appears also 

 to be dispersed along the whole coast of West-Finmarken, but here 

 apparently less numerous, except perhaps in the most eastern part 

 of this district. It has been found at Kistrand in Porsangerfjord 

 (f. typica and f. toralosa), Kjelvik, Magero Sound, Maaso, Gjes- 

 vser, Kvalsund (f. torulosa) and Bergsfjord. Within Tromso Amt 

 Kjellman collected it at Karlso, and I found a small specimen in 

 Polden in the inner part of the Lyngen Fjord. I also met with 

 some few specimens at Tromso and Mestervik in Malangen, but 

 they are sterile and rather- uncertain. Within Nordlands Amt Kleen 

 1. c. quotes it from Fleinvaer and Givser, not far from Bodo, and 

 I gathered a specimen, however, uncertain at Borgevser in Lofoten, 

 apparently anastomosing with L. varians and mentioned under 

 this species.
