SPECIES ON THE ALGAL GENUS VAUCHERIA ON THE FAROES
Figs. 1-5. The representative ofthe V. geminata complex commonly found along Faroese streams and ditches. I:
from sample 3. 2: sample 6. 3: sample 16. 4: sample 6. the only four-sporedfruiting branch seen. Materialpre-
served in nature. 5: sample 8. The two fruiting branches are on the same filament but ratherfar apart.
pachyderma Walz var. islandica Børgesen
but smaller, and one as V. hamata (Vauch.)
Lyngb. The two species last mentioned are
discussed below under V. dillwynii and V.
uncinata, respectively.
In the first half of July 1994 I had the op-
portunity to work at the BIOFAR Labora-
tory in Kaldbak north of Tórshavn. Dr.
Arne Nørrevang, head of the laboratory,
and Ruth Nielsen, Botanical Museum of
Copenhagen, then unđertook a tentative
semiquantitative investigation of plant and
animal communities around the islands in
collaboration with their diving colleagues
Dr. Karl Gunnarsson, University of Reykja-
vík, and Kim Lundshøj, Copenhagen. I was
permitted to go with this working group to
selected localities on the islands and thus
could collect Vaucheria samples in distant
parts of the archipelago. I am very grateful
to my colleagues for this opportunity and
for the help received during the stay. The
following is an account of what I found.
Undoubtedly the list of species is still in-
complete, but it fills some phytogeographi-
cal gaps as it is.

The samples were taken in the following
stations, listed with geographical coordi-
nates in kilometres according to the UTM
system:
