The Færoese specimens agree very well with Kuckuck's 

 description and figures. They have frequently 2 — 3 and sometimes 

 even 4 terminal sporangia on each branch (see fig. 74), but very

In November it was found bearing a quantity of unilocular 



sporangia and Jonsson observed swarmspores in abundance when 



he looked through the material immediately after gathering.
