from the cylindric form (fig. 23 C). These plants are lower than the main form 
and usually branched from the base, while the main form is most often without

branches below. In the 
specimens from VT the 
sporangia were almost al- 
ways sessile, alternate, se- 
cund or opposite (fig. 23 
A), while in the speci- 
mens from KC they were 
often stalked (fig. 23 C). 
This form may be named 
f. brevior. 
The specimens just 
described are only slight- 
ly different from others 
agreeing with Kyrıns Ch. 
parvula. Fig. 25 shows 
such a specimen, the fila- 
ments of which are 5—7 u 
thick and the cells about 
twice as long as broad; the sporangia, however, were somewhat larger than indi- 
cated by Kyrın, namely (10—) 12—13 (—14) 4 long, 
cell was (10—) 12—13 (—15) » in diameter. Some 
specimens growing on the frond of Porphyra umbi- 
licalis on the mole of Frederikshavn (fig. 26) may 
also be referred here, though they were not strongly 
ramified in one plane; they bore numerous spor- 
angia, most often opposite, sometimes even three in 
one article. The axile chromatophore is very distinct 
in the figures which have been drawn after speci- 
mens preserved in alcohol. The last-named speci- 
mens as well as those from EM (fig. 25) were only 
provided with sporangia; on the other hand, spe- 
cimens from BH (fig. 24) had also sexual organs. 
Fig. 24 B fully agrees otherwise with Kyrın’s figures, 
while fig. 24 A might perhaps be better referred to 
f. brevior, but these plants grew side by side and 
were connected by transitional forms. A very re- 
duced plant provided with all kinds of organs of 
reproduction is shown in fig. 24 C. It seems not im- 
probable that the small cells shown in Kyrıy’s fig. 
9h, i (1906) may have been antheridia.
