S. cliffwetmorei S. eos S. gintarasii S. maccarthyi Sirenophila is a genus of crustose lichens in the subfamily Teloschistoideae of the family Teloschistaceae.

The genus was circumscribed in 2013 by Ulrik Søchting, Ulf Arup, and Patrik Frödén, with Sirenophila gintarasii assigned as the type species.

The generic name Sirenophila, which means "loving mermaids", alludes to the habitat preference this genus: seashore rocks in Australia and New Zealand.

The authors included seven species in their original conception of the genus,[2] but Sirenophila bermaguiana, S. gallowayi, and S. jackelixii have since been transferred to genus Elixjohnia,[3] while S. tomareeana is now in Tarasginia.

The ascospores are polaridiblastic (pierced by a narrow channel) with a long septum.
