This species which has been found only in two localities in the Baltic is cer- 
tainly nearly related to Ch. hallandica, but however so different from it, that I do 
not hesitate to set it up as a distinet species. It differs by the primary filaments

being more numerous, less bran- 
ched, somewhat thicker and con- 
sisting of somewhat longer cells, 
by the sporangia being larger, by 
the sporangial stalks bearing only 
one sporangium, and by the want 
of sexual organs. In some of the 
characters mentioned, the more 
numerous and thicker filaments, 
and the sporangia often opposite, 
it resembles Ch. hallandica f. par- 
vula, but it is very different from 
this by the long cells and the 
) sporangia being often stalked. 
To complete the description 
given above, the following re- 
marks may be added. The basal 
cell is nearly globular, its plane 
of attachment being often smaller 
than its transverse section; it is 
rather thick-walled. The primary 
filaments bear usually no long 
branches but only sporangia- 
bearing branchlets. The most de- 
veloped primary filaments recall 
somewhat those of Ch. virgatula, 
but they are thinner and the 
branchlets bear only one spor- 
angium. The shorter filaments 
consist of shorter cells, 2—3 times 
as long as broad and often some- 
what enlarged above. In some 
specimens from SQ the longer 
filaments were up to 9 thick below, upward thinner, ca. 5 in diameter, the cells 
being up to 7 times as long as broad. The chromatophore reaches in the longer 
cells often only to the middle of the cell, the pyrenoid lies near the upper end of 
the cell. The spores contain a very distinct stellate chromatophore. I have never
