The extinct genus Hedstroemia was once thought to be a rivulariacean cyanobacterium.[needs update?] It forms oval blobs composed of sinuous tubes that have rounded outlines and occurs in conjunction with Solenopora.[3]
Hedstroemia was formerly assigned to the now obsolete taxon porostromata.[4] In 2020, the genus was assigned to the cyanobacteria order Nostocales.[5]
