On the whole So/oriiia bispora has the same distribution as 6". spoiigiosa, 

 but it is more common, especially on the mountains of Southern Norway. 



Several specimens labelled Soloriiia spougiosa (or S. liiuhata) in her- 

 baria belong here. Th. Fries describes the distribution of ^Soloriiia saccata 

 ß. linibafa (Somrft.)' as follows: optima ad litora marina Nordlandiae, Fin- 

 markiae et Groenlandiae passim.' (Lieh. Arct. p. 49). This evidently inclu- 

 des Soloriua spoiigiosa as well 6". bispora. 



The spores are variable: Length from 50 — 100 [jl, usually one-septate, 

 but also (rarely) bi-septate, and (very rarely) undivided.
