Boodlea is a genus of green algae in the family Boodleaceae. [1] Species may be known as crunchy hair grass. [2]
The algae grows brittle, filamentous hair-like growths. It is known as a pest in marine aquaria. [2]
Boodlea was named after the British botanist and public servant Leonard Alfred Boodle in J. Linn. Soc., Bot. vol.25 on pages 243-245 in 1889. [3]
Pelvetia canaliculata, the channelled wrack, is a very common brown alga (Phaeophyceae) found on the rocks of the upper shores of Europe. It is the only species remaining in the monotypic genus Pelvetia. In 1999, the other members of this genus were reclassified as Silvetia due to differences of oogonium structure and of nucleic acid sequences of the rDNA.
Polysiphonia, known as red hair algae, is a genus of filamentous red algae with about 19 species on the coasts of the British Isles and about 200 species worldwide, including Crete in Greece, Antarctica and Greenland. Its members are known by a number of common names. It is in the order Ceramiales and family Rhodomelaceae.
Derbesia is a genus of green algae in the family Derbesiaceae. The plant was originally known from different names applied to its larger sporophyte, Derbesia, and its less conspicuous gametophyte, Halicystis. Derbesia was successfully cultured in the laboratories of German phycologist Peter Kornmann to learn that both it and the plant Halicystis were different parts of the life cycle of the same organism.
Draparnaldia is a genus of freshwater green algae in the family Chaetophoraceae. Draparnaldia are uniseriate; each filament is composed of a chain of cells arranged in one row. Chloroplasts appear as a band within the center of each cell. The length of the main axis cells are generally the same, regardless of whether or not they bear branches. These side branches are divided extensively into terminal hairs. The entire plant is enveloped in loose, slippery mucilage. Draparnaldia is a cosmopolitan genus with wide distribution and it is usually found in cold aerated waters. They are either attached to sand or grow epiphytically on other aquatic plants. Draparnaldia can be seen growing in clear streams trailing on stones and boulders. Herman S. Forest of The Southern Appalachian Botanical Club has stated that while not common, it is present frequently enough to be recorded in almost all local flora lists of green algae that have been compiled. A multitude of species are present in Lake Baikal, Siberia and have been described by Meyer and Jasnitzky. A species of the genus had been placed and described in the Linnean Herbarium as Conferva mutabilis Roth in 1797. Nowadays Conferva is no longer used and the species is described as Draparnaldia mutabilis (Roth) Bory. Bory is added in honour of the researcher of the same name, based on whose description the genus was separated from similar appearing forms. Bory is accredited with the establishment of the genus.
Paulschulzia is a genus of green algae, specifically of the family Tetrasporaceae.
Rosenvingiella is a genus of green algae in the family Prasiolaceae.
Schroederiella is a genus of green algae in the family Scenedesmaceae.
Tellamia is a monotypic genus of green algae, in the family Kornmanniaceae. It has only one known species, Tellamia contortaBatters, 1895
Zoddaea is a monotypic genus of green algae in the family Chaetophoraceae. It only contains one known species, Zoddaea viridisBorzì
Valkanoviella is a monotypic genus of green algae, in the family Chlorococcaceae. It only contains one known species, Valkanoviella vaucheriaeBourrelly, 1965.
Calkinsia is a monotypic genus of excavates comprising the single species Calkinsia aureus. It lives in low-oxygen seafloor environments. It is not classified in any of the three well-known groups of the Euglenozoa, but is placed in its own group, the Symbiontida. Some authors have classified Calkinsia alongside Postgaardi, but Postgaardi has not been studied well enough to test this hypothesis.
Loefgrenia is a monospecific, freshwater, epiphytic genus of nonheterocystic cyanobacteria known from Brazil.
Martensia is a genus of red algae, containing the following species:
Ralfsia verrucosa is a species of crustose brown seaweed in the family Ralfsiaceae. It grows intertidally in temperate waters around the world. In South Africa it is part of a mutualistic relationship with a limpet.
Cutleria is a genus of brown algae, one of 2–6 genera in the order Cutleriales. AlgaeBase recognises 11 species in the genus.
Entwisleia is a monotypic genus in the red algae family, Entwisleiaceae. There is just one species in this genus, Entwisleia bella, from south-eastern Tasmania and represents both a new family and a new order (Entwisleiales) in the Nemaliophycidae.
Zanardinia is a monotypic genus of seaweed in the brown algae. The only species, Zanardinia typus, commonly known as penny weed, is native to the northeastern Atlantic Ocean and the Mediterranean Sea.
Crouania is a genus of red algae (Rhodophyta) in the Callithamniaceae family. The name of the genus honours the French born Crouan brothers, Pierre-Louis Crouan and Hippolyte-Marie Crouan. It was first described by Jacob Georg Agardh in 1842, and the type species is Crouania attenuata.
Wislouchia is a genus of chlorophyte green algae. The name was first published in 2021, as a replacement name for Raciborskiella. As of February 2022, it was the only genus in the family Wislouchiaceae.
Alvikia is a monotypic genus of green algae in the class Chlorophyceae. Its taxonomy is uncertain. It only contains the known species of Alvikia littoralis.
