Fritschiella aquatilis is a species of freshwater green alga in the family Chaetophoraceae.[1] It features a unique globular, hairy morphology. It was discovered in the city of Taiyuan, Shanxi province, China, and can be found in freshwater aquariums with ornamental fish. The species exhibits some differences from the closely related Fritschiella tuberosa, which is primarily found in soil environments. Molecular phylogenetic data has supported the classification of F. aquatilis as a new species within the genus Fritschiella.
Phylogeny
Fritschiella aquatilis was scientifically described as a new species in 2019 by a group of Chinese scientists. The species epithet, aquatilis, refers to its freshwater habitat. The type specimen was collected in Taiyuan City, Shanxi Province, China, in a freshwater aquarium containing ornamental fish. The holotype is deposited at Shanxi University under the voucher number SXUHB-170501.[2]
Molecular phylogenetic analysis using 28S rDNA, 18S rDNA, and rbcL gene sequences has indicated that F. aquatilis is a distinct species in the genus Fritschiella. The analysis also revealed a close relationship between F. aquatilis and F. tuberosa, but with significant genetic differences between the two species. The occurrence of compensatory base changes (CBCs) and hemi-CBCs in the ITS2 secondary structure further supports the classification of F. aquatilis as a new species.[2]
