Type: Johnsonia spinosa Korde (monotypic genus at the time of publication).

Notes: This alga has been found in Upper Permian deposits from Russia. It was synonymised by Kuss (1994) with Likanella Milanović , despite the clear difference outlines by Milanović (1965) between the two genera. Based on the assessment by Granier & Michaud (1990), it has been treated since as a taxonomically accepted genus, closely allied to other calcareous groups ( Hosseini & al. 2014).
