that of a specimen from Norway (Brodie,
pers. obs.) and might represent a more
northerly element of the flora.
The possibility that some specimens cur-
rently placed as Porphyra sp. 4 may repre-
sent a separate species, possibly P. insolita
needs to be determined. P. insolita was only
recently described as a new species (Kom-
mann and Sahling 1991) and it is apparent
that it has been confused with P. umhilicalis
and P. purpurea in the northeast Atlantic.
However, in the absence of a type specimen
for P. insolita and conflicting molecular
data (Brodie, pers. obs.), further studies are
required to determine whether this is a dis-
tinct taxon.
A number of other specimens remain
unidentified in the collection and it is pos-
sible that there are other undescribed
species present, but this requires further
molecular studies to determine the exact
identity of such individuals.

ed in the fieldwork and assisted in many
ways in the field as well as in the laborato-
ry. Peer Corfixen, Botanical Museum,
Copenhagen maintained the database. The
programme was supported financially by
