thallus in small, short, densely matted growths. Plurilocular spo¬ 
rangia were observed in April. 
Found hitherto only on Str.: near Thorshavn (!).

Specimens exactly agreeing with Sauvageau’s exhaustive descrip¬ 
tion and figures have been found epiphytic on Monostroma fuscnm. 
This species bore both unilocular and 
plurilocular sporangia in July. 
Found hitherto only on Str.: in Sundene 
between Thorsvig and Kvalvig (!).

ques Myrionemacees, p. 77. 
Occurred on the lamina of Laminaria 
digitata as small, short, dense, roundish, 
cushion-like growths. In fig. 80 is shown a 
portion of the plant with plurilocular spor¬ 
angia (b), a hair (a), and a small portion of 
the basal disc (c). The plant bore plurilo¬ 
cular sporangia in May which were 5 y 
thick. Professor Sauvageau to whom I 
sent a preparation corroborates my deter¬ 
mination. 
Found only on Syd.: Famien (!).

To this species I have referred a small alga which occurred 
as a short, dense covering on the lamina of Laminaria hyperborea. 
It closely resembled Reinke’s var. seriata (Atlas, tab. 16, tigs. 5—12), 
but the plurilocular sporangia, unlike what is said to be the case 
in Reinke’s variety were occasionally divided by longitudinal 
walls. Reinke writes with reference to his variety (1. c. p. 19).
