  Systematics of Plocamium pacificum
The plant body of an alga is referred to as the thallus, and in this subclass it is filamentous with pseudoparenchymatous development.
This means that the cells that compose the thallus are in a linear arrangement and those that are next to each other are not necessarily the result of the same cellular division.
Florideophyceae algae are multi cellular, when they grow they do so by producing new cells at the end of branches, apical growth.

 Delesseria decipiens taxonomy
The Class Florideophyceae is a diverse group of red alga containing species as seemingly different as the coralline algae and Botryocladia, the sea grapes.
These algae are all united, however, by morphological similarities such as filamentous or pseudoparenchymatous construction, apical cell division, the formation of pit connections, and dioecious gametophytes.
In addition, members of the class Florideophyceae also have carpogonia located on a trichogyne, as well as carpospores that form on gonimoblast filaments.

 Florideophyceae
The Florideophyceae is a well-defined assemblage of red algae that share a number of characters including the presence of tetrasporangia, and a filamentous gonimoblast.
Hypothesized relationships in the Florideophyceae are in a state of flux.
Interpretation of these characters is therefore difficult, and in turn has prevented the establishment of solid hypotheses for higher-level relationships in the Florideophyceae.

 TAXONOMY   (Site not responding. Last check: 2007-10-31)
One is Florideophyceae and the other is Bangiophyceae.
The Florideophyceae class contains all other and opposite characterisitcs, such as cells having pit connections, and apical cell division with a triphasic life cycle.
Since Corallina vancouveriensis does not fit in the Bangiophyceae class, because it has pit connections, apical growth and a triphasic life cycle, it is in the Florideophyceae class.

 Chondracanthus life history
The life histories of all red algae are fairly complex, and that of C.
It may be useful to look at a quick run down of the basic life history of the Rhodophyta, specifically those in the subclass Florideophyceae, before delving into the specifics of C.
This diagram depicts a simplified version of the Florideophyceae life history.

 RHODOTISTA
In this system, the red algae are divided into two major groups, Bangiologia ("Bangiophyceae") and Florideologia ("Florideophyceae").
Garbary and Gabrielson (1990) question the need of dividing the red algae into two groups and prefer to lump all of the orders into a single class.
(1994) who compared plastid DNA within the phylum show that the orders of the Florideophyceae form natural groupings.

Traditionally the red algae were divided into two Classes the Bangiophyceae and Florideophyceae.
Alternatively a single Class, the Rhodophyceae and two Subclasses, Bangiophycidae and Florideophycidae are used.
Based on ultrastructure and molecular evidence the Bangiophyceae is now accepted as a paraphyletic group, while the Florideophyceae is considered to be monophyletic based on two synapomorphic characters - presence of a filamentous gonimoblast and tetrasporangia (Garbary and Gabrielson 1990 [and references within], Ragan et al.

Nuclear small-subunit and partial large-subunit rDNA sequences were determined for the freshwater rhodophyte species Ballia prieurii, from northern Brazil, to assess its relationship to the marine species that have recently been transferred to a new order, Balliales, in the Florideophyceae.
Ballia prieurii unequivocally associated with species of the freshwater order Batrachospermales, rather than with the marine Balliales, in all molecular analyses.
