S. filifera S. flagellata S. sinensi Serusiauxiella is a genus of leaf-dwelling lichens in the family Strigulaceae.

It has three species, all of which are found in wet tropical forests in China.

[1] The genus was circumscribed in 2020 by Shu-Hua Jiang, Robert Lücking, and Jiang-Chu Wei, with Serusiauxiella filifera assigned as the type species.

[2] The three species in the genus are characterised by having macroconidia with appendages that rapidly elongate (up to 70 μm) after waiting up to 1 hour in microscope slide preparations called squash mounts.

The photobiont partner is a green alga of the genus Trentepohlia.
