Abstract:
Study of the north Alaskan brown algal epiphyte
Chukchia pedicellata sp. nov. suggests an apparently
close relationship to Phaeostroma. Phaeostroma
endophyticum S. Lund from east Greenland, Bylot
Island, Nunavut, Canada, shows generic identity with
Chukchia and specific differences from C. pedicellata.
Comparison of C. pedicellata and P. pustulosum Kuck.
(the type species of Phaeostroma) shows morphological,
cytological, reproductive, and distributional
differences. We recognize novelty of C. pedicellata
and necessity to broaden the species description of
P. endophyticum, which becomes Chukchia endophytica.
C. endophytica is distinguished by its dimorphic
vegetative habit, its large plurilocular sporangia, and
the putative ability of the sporangia to digest host tissue
to accommodate development within the host.
Absence of pyrenoids and novel plurilocular sporangia
in both species suggests that they are not members
of the Ectocarpales, sensu lato.
