38 CORALLINE RED ALGAE (CORALLINALES, RHODOPHYTA) OF THE FAROE ISLANDS
Material and methods
Algae were collected selectively by hand
from the littoral to 30 m depth, in the sub-
littoral by SCUBA diving; in addition ma-
terial was obtained by dredging at a few of
the 265 stations. Collections were made at
all seasons, but less in the winter months,
with only a small collection from January,
and none from November, December and
March. The localities visited were distrib-
uted on most of the larger islands and in-
cluded places on the open coasts with dif-
ferent exposure to waves as well as more or
less sheltered places in the fjords. Informa-
tion about the localities with details of col-
lection dates, depth and geographical coor-
dinates for each station, are available in
Sørensen et al. (2001) while amap showing
the locations is available in Nielsen and
Gunnarsson (2001). The main part of the
obtained material was dried immediately
after collection, but a smaller fraction was
stored in a 7:2:1 solution of ethanol. dis-
tilled water and gl'ycerol to keep it moist.
For identification it is often necessary to
decalcify and section the specimens.
The material was decalcified overnight
in dilute (2-5%) acetic acid, then rinsed
once in distilled water. Part of the material
was embedded in Cryo Embed (AX-LAB
A/S, Copenhagen, Denmark). Sections of 8
pm were cut on a Reichert-Jung 2800
Frigocut microtome (freeze microtome),
collected on a slide, stained with few drops
of 1% Cotton Blue dissolved in lacto glyc-
erol (875 ml lactic acid, 63 ml glycerol, 62
ml distilled water) and mounted in 35-50 %
KARO® (com syrup). Another part was
embedded in LR-White resin (London
Resin Company, UK), cut on a Reichert-
Jung 2050 Supercut microtome in sections
of 7 pm and mounted for permanent slides
in Eukitt (Bie and Bemtsen, Denmark).
This method is modified after Woelkerling
(1988); for methodological details see
Díiwel and Wegeberg (1996).
Voucher specimens are kept in the
Botanical Museum, Copenhagen (C) with
duplicate collections in the Museum of
Natural History, Tórshavn and the Marine
Research Institute, Reykjavik, Iceland.
Results
Taxonomy and nomenclature generally fol-
low Chamberlain and Irvine (1994a, b) and
Irvine and Johansen (1994). Authors of
plant names are abbreviated according to
Brummit and Powell (1992). Included in
the list as synonyms are names used by
Børgesen (1902), Irvine (1982) and Sim-
mons (1897). For each species at least one
reference indicates a good description, il-
lustration, or other specific information.
The BIOFAR stations where the respective
species were collected are listed as well as
notes recording depth distribution,
month(s) of collection and observations of
reproductive structures.
The list of species includes the following
symbols:
*: new or previously unpublished records
for the Faroe Islands.
(): collection from a wide depth range.
Depth distribution: Only handpicked mate-
rial included.
