Sirodotia huillensis (Welwitsch ex West & G.S.West) Skuja[1] is a freshwater red algal species belonging to the family Batrachospermaceae.

S. huillensis ranges from 6–10 cm tall, the thallus is moderately mucilaginous and abundantly branched.

Primary and secondary fascicles (whorls) are produced all along the plant body which gives a beaded appearance to the thallus.

It is slightly curved with distinctly stalked cylindrical trichogyne on the dorsal side of asymmetrical carpogonia.

[2] S. huillensis occurs strictly in freshwater and grows in high altitude streams with low temperatures.
