Abstract:
Adenocystis utricularis f. longissima, described
by Skottsberg (1921), is a little-known brown alga with a
restricted austral distribution (South American regions
of Patagonia, Tierra del Fuego, the Falkland Islands
and South Georgia). It has not been re-examined after
its description. We have studied field thalli and laboratory
cultures of this alga from southernmost South
America and compared them to those of the typical form
of A. utricularis from the same region. Significant differences
were found between the taxa in morphology of
both adult field thalli and juvenile stages in culture. In
nature, both taxa occurred in mixed populations without
intermediates. Based on these results, we propose to
elevate A. utricularis f. longissima to species rank. Syntype
material of A. utricularis f. longissima from Uppasala
University (UPS) was examined and a lectotype was
designated. Adenocystis includes three species:
A. longissima, A. rimosa and A. utricularis.
