Florideophyceae
Florideophyceae is a class of red algae. They were once thought to be the only algae to bear pit connections, but these have since been found in the filamentous stage of the Bangiaceae. They were also thought only to exhibit apical growth, but there are genera known to grow by intercalary growth. Most, but not all, genera have three phases to the life cycle. Classification There are various classification schemes; see red algae. One option is to use the following: Subclass Hildenbrandiophycidae * Hildenbrandiales Subclass Nemaliophycidae * Acrochaetiales * Balbianiales * Balliales * Batrachospermales * Colaconematales * Nemaliales * Palmariales * Entwisleiales * Thoreales Subclass Corallinophycidae * Corallinales * Corallinapetrales * Rhodogorgonales * Sporolithales The subclass Corallinophycidae was introduced in 2007.

Red Algae
Red algae, or Rhodophyta (, ; ), are one of the oldest groups of eukaryotic algae. The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority of species (6,793) are found in the Florideophyceae (class), and mostly consist of multicellular, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats but relatively rare in freshwaters. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations found in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, there are no terrestrial species, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity. The red algae form a distinct group characterized by having eukaryotic cells without flagella and centrioles, chloroplasts that l ...

Entwisleia
''Entwisleia'' is a monotypic genus in the red algae family, Entwisleiaceae. There is just one species (the type species) in this genus, ''Entwisleia bella'', from south-eastern Tasmania and represents both a new family and a new order in the Nemaliophycidae. It is a marine species found in the Derwent River estuary. It grows at depths between 5.0 and 9.0 m and is found scattered on mudstone reef flats dusted or shallowly covered by sand. The site at which it was found is subject to episodic high-rainfall events throughout the year and heavy swells in winter. It is a feathery dioecious seaweed, very like the freshwater red algae, '' Batrachospermum,'' but from DNA sequencing, appears to be quite unrelated. Scott ''et al.'''s (2013) study shows it as a sister clade of the Colaconematales. The genus was named to honour Tim Entwisle, was circumscribed In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the ...

Hildenbrandiales
Hildenbrandiales is an order of crustose forms red alga which bear conceptacles and produce secondary pit-connections. They reproduce by vegetative gemmae as well as tetrasporangia, which are produced inside the conceptacles. The way in which the tetraspores are produced is unusual enough to justify the formation of this distinct order. Some members of the order are known from freshwater rivers as well . Systematics Hildenbradiales are difficult to discriminate on morphological grounds; tetrasporangia morphology is the only vaguely reliable character, but molecular techniques have indicated a monophyletic '' Apophlaea'' within a paraphyletic ''Hildenbrandia ''Hildenbrandia'' is a genus of thalloid red alga comprising about 26 species.
