Urospora wormskjoldii (Mert.) Kolderup Rosenvinge. var. van-
couveriana n. var.
Frond attached, soft, gelatinous, dark green* filaments unbranched, 1-1.5
dm. in length, of different sizes, narrow at base, above dilated and moni-
* ' . .... * . *
liform ; articulations at base 75-130 mic. in width, near apex (filled with
macrozoogonidia) up to 3mm in width; lower and median articulations
f cylindrical, upper articulations ventricose, either spherical or ovoid-ellip-
soid, equal up to three times longer than broad; basal cells, 14-20 in num-
ber, giving off rhizoidal filaments which grow downward and attach the
plant to substratum (as in Bangia); macrozoogonidia ovoid, wit’ll four
cilia at anterior end, and with posterior end drawn out into a spine
10-12 x 28-32 mic.

i Cladophora et Chsetomorpha, in 6ot. Tidsskr. 18:64. 1892. The author
mentions! the occurrence of external rhizoids applied to the surface of
jower /cells ip Chsetomorpha wormskjoldii Kjellm. (Conferva worsm-
kjoldii Mert.) and makes the statement t^hat since the zpospores have
four cilia and a spine-like posterior end, this species should be placed in
.. the genus Urospora. • . v	<'
The variety differs from the species, hitherto reported only from Greenland,
in being much larger and in having filaments not becoming attenuate at

the ends.
