gust and September, carpospores (and spermatia?) in August and 

 September. 



Occurrence. The species appears to be dispersed along the 

 whole coast of Finmarken and in several places abundant, as 

 Lebesby in East-Finmarken, Magero (Kj ell man), Repvaag and 

 Kistrand in West-Finmarken. Cp. Kjellm, and Fosl. 1. c. Within 

 Tromso Amt for inst. at Skorpen, Karlso (Kjellm an) and Tromso, 

 plentiful. In Nordlands Amt it is common and abundant according 

 to Kleen 1. c. Within Nordre Trondhjems Amt I met with it at 

 Frojen and Frooerne, at the latter place local but plentiful. It 

 has probably also been found at Christiansund, N. (Ekman). 



Q-eogr. Distribution. The White Sea (Gobi); Iceland (Strom-

Description of the species. This species is rather puzzling. 

 I have seen but a solitary, somewhat fragmentary and sterile spe- 

 cimen. It most probably has been attached at first to some hard 

 object and afterwards detached itself. The frond has the appea- 

 rance of a low bush, about 5 cm. high, with a very short main- 

 stem, and from this issue irregularly divided branches, which in 

 the lower part attain a thickness -of up to about 3 mm., much 

 attenuating upwards and the ultimate ones only 1 — 1.5 mm. thick. 

 They are more or less patent and bent, or flexuous, or in the 

 upper parts of the frond curved, terete or nearly terete, and put 

 forth nearly everywhere rather numerous branchlets, which are 

 frequently thinner than their main-axes, not seldom only one half 

 or even one third, either simple or irregularly divided, spreading,
