Gliederzellen in Sporangien um«. Thus, according to Reinke this 
variety has properly speaking no erect filaments, they being 
all transformed into sporangia, and I have noticed the same to 
be the case in the Faerdese specimens. On this point Sau- 
vageau (1. c. p. 10) appears to have mis¬ 
understood Reinke’s description, and if 
we follow the view of Kuckuck, who 
regards the absence of erect filaments as 
a characteristic mark of the genus Phy- 
cocelis , then M. foecundiun ought to be re¬ 
garded as a typical Phycocelis, but I think 
with Sauvageau that these two genera 
can practically hardly be kept distinct. 
Fig. 81 represents some fragments of 
this plant. The plurilocular sporangia are 
about 8—9 y broad. 
It bore plurilocular sporangia in May. 
Found hitherto only on Str.: Thors- 
havn (!).

Found in the lamina of Laminaria fceroensis , and agrees fairly 
well with Rosenvinge’s description and figure (1. c.) as also with 
Kuckuck’s (1. c.). The Faeroese specimens come near the Greenland 
and Heligoland specimens in not having the vertical, vegetative, 
assimilative filaments described by Foslie (New or critical Norw. 
Alg, p. 24). 
Plurilocular sporangia were met with in abundance, and in a 
vigorously developed plant there occurred just a few unilocular 
sporangia of the same form as those figured by Rosenvinge. 
Sporangiferous specimens were observed in October. 
Found hitherto only in the following places: — Ost.: Skaalefjord 
(H. J.); Str.: Kvalvig (H. J.). If searched for more closely it will doubt¬ 
less prove to be commonly distributed.
