Batrachospermaceae
Batrachospermaceae is a family of fresh water 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 ... (Rhodophyta). Genera within the Batrachospermaceae generally have a "''Lemanea-''type" life history with carpospores germinating to produce chantransia. Sporophyte phase with meiosis occurs in an apical cell to produce the gametophyte stage. Pit connections have two pit plug cap layers with the other layer enlarged. This family of freshwater red algae is uniaxial, meaning each filament with a single apical cell. The genera included within Batrachospermaceae are listed in the table below.

Sirodotia
''Sirodotia'' Kylin (1912) is a genus of freshwater red alga which was described by Harald Kylin, Kylin in 1912, and placed in the Batrachospermaceae family. The genus name of ''Sirodotia'' is in honour of Simon Sirodot (1825–1903), who was a French botanist, Phycology, algologist and teacher. He was also a Zoologist and Archaeologist, who taught at schools in Toulouse, Strasbourg, Le Mans, Cahors and Limoges. Taxonomy The family Batrachospermaceae belongs to the order Batrachospermales and has six well known genera namely ''Batrachospermum'', ''Kumanoa'', ''Sirodotia'', ''Nothocladus'', ''Tuomeya'', and ''Sheathia''. The morphology of the gametophyte of ''Batrachospermum'', ''Sirodotia'', ''Tuomeya'', and ''Nothocladus'' are more are less similar to each other. Necchi and Timothy John Entwisle, Entwisle (1990) proposed to delimit them from generic level to section level of genus ''Batrachospermum''. ''Sheathia'' was the member of genus ''Batrachospermum'' and has risen to gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
