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.
