Liagoraceae
Liagoraceae is a family of red algae (Rhodophyta) in the order Nemaliales. The type genus is ''Liagora'' . It was originally called ''Helminthocladiaceae'' by J.Agardh in 1851, but P. Silva in 1980 stated that this was predated by Liagoraceae which was published in 1843. Various authors over several years, had tried to form tribes within the family, but it was found (each time) that the family is not able to be divided naturally. As the morphological character analyses show too much variation. The family was found to be polyphyletic (having a mixed evolutionary origin) based on analyses of rbcL enzymes. The 2 genera of ''Yamadaella'' and ''Liagoropsis'', which were previously placed in the Dermonemataceae family, were found to have independent lineages and could be recognized as two new families ''Yamadaellaceae'' and ''Liagoropsidaceae''. Description Many species are irregular and paniculate (much-branched). They have a basic dichotomous branching but with numerous proliferous ...

Gloiotrichus
Gloiotrichus is a genus of red algae, from the Liagoraceae family, characterised by its particularly mucilaginous thalli." It forms a pyramidal shape due to its vegetative structural development, the thalli being composed of several terete main axes with lateral branches similar in structure. The species is characterised by "the development of sterile filaments on the elongate carpogonial branches that have the appearance of normal cortical filaments." It has one known species, ''Gloiotrichus fractalis,'' found only in the Houtman Abrolhos in Western Australia.

The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing.

Ganonema
Ganonema is a genus of red algae, from the Liagoraceae family, characterised by its dichotomously branched, multiaxial thalli, with terete axes." It is closely related to '' Liagora'', but can be distinguished in two important respects. Its vegetative structure is distinct, as the basal cells of its cortical fascicles are isodiametric, whereas the cells of ''Liagora'' are elongate. Also, its reproductive development features "the occasional production of carpogonial branches in clusters and the production of spermatangia in dense heads." Species Species in this genus include: * '' Ganonema codii'' * '' Ganonema farinosum'' See also * Algae * Red algae * Algae eater Algae eater or algivore is a common name for any bottom-dwelling or filter-feeding aquatic animal species that specialize in feeding on algae and phytoplanktons. Algae eaters are important for the fishkeeping hobby and many are commonly kept b ... References {{Alga-stub Red algae genera N ...

Dotyophycus
Dotyophycus is a genus of red algae, from the family Liagoraceae, characterised by a " terete, dichotomously divided, calcified thallus." It can be recognised by its reproductive features, particularly the gonimoblast that follows fertilization and the absence of sterile cells in mature cystocarp. Visually it is distinguished by its "almost creamy-white" appearance derived from its outer mucilage and calcification Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone, but calcium can be deposited abnormally in soft tissue,Miller, J. D. Cardiovascular calcification: Orbicular origins. ''Nature Mat ....

Hainan Island
Hainan (, ; ) is the smallest and southernmost province of the People's Republic of China (PRC), consisting of various islands in the South China Sea. , the largest and most populous island in China,The island of Taiwan, which is slightly larger, is claimed but not controlled by the PRC. It is instead controlled by the Republic of China, a ''de facto'' separate country. makes up the vast majority (97%) of the province. The name means "south of the sea", reflecting the island's position south of the Qiongzhou Strait, which separates it from Leizhou Peninsula. The province has a land area of , of which Hainan the island is and the rest is over 200 islands scattered across three archipelagos: Zhongsha, Xisha and Nansha. It was part of Guangdong from 1950–88, after which it resumed as a top-tier entity and almost immediately made the largest Special Economic Zone by Deng Xiaoping as part of the then-ongoing Chinese economic reform program.
