The disporangia are of the same size 
as the tetrasporangia, or, when only the 
specimens within Skagen are taken into ac- 
count, generally larger than the tetrasporan- 
gia, viz. 56—78u long, 43—65 broad. The 
size was rather variable in specimens from 
different localities. Thus in specimens from 
Feno Sund gathered in June the disporan- 
gia were 56—60 w long, 43—47 w broad, 
while in specimens from a locality north of S 
Æro gathered in May, they were 67—78 u 
long, 53—63 u broad. The disporangia were 
formerly mentioned by Kyrın (1907, p. 169) 
who raises the question whether they might 
possibly be young stages of tetrasporangia. Fig. 267. 
He arrives at the conclusion that they are aie ME DA ea 
fully developed, partly on account of the 
fact that he found some of them emptied, which conclusion I can fully confirm. 
The disporangia-bearing specimens in all other respects fully agree with the 
tetrasporangia-bea- 
ring ones so there 
seems to be no 
sufficient reason to 
consider them as 
a special variety. 
They occur more 
rarely than the 
others; in Fæno 
Sund both kinds of 
individuals have 
been met with. The 
disporangia are di- 
vided by a horizon- 
tal wall on each 
side of which a 
large nucleus is si- 
tuated. A finer cy- 
tological investiga- 
tion of the dispo- 
rangia is much
