Some botanists recognize a class Bangiophyceae to include all red algae
that, like Porphyra, lack
pit connections from at least some vegetative phase of the life history.
However, this practice
is becoming less common, because it appears the "bangiophytes" are
paraphyletic with respect
to the origin of the red algae and especially the origin of those reds
(the "florideophytes") that
have pit connections in all vegetative life history stages.
