Trochiliscaceae is a family of fossil charophyte green algae.[1] It is the only member of the order Trochiliscales.[2] The reproductive structures in Trochiliscaceae (and families placed in Sycidiales by AlgaeBase) have a calcified cover, called a utricle, that is thought to prevent the zygote being desiccated. Other Paleozoic families lack this cover, as do modern charophytes. Fossils of Trochiliscaceae are from the Devonian.[3]
Genera
(As of February 2022), AlgaeBase accepted the following genera.[1]
- †Karpinskya (Croft) Grambast – 2 species
- †Moellerina E.O.Ulrich – 3 species
- †Primochara T.A.Istchenko & Saidakovsky – 2 species
- †Trochiliscus Karpinsky – 7 species
