Original Description

[Jones 1875]: See Ramulina laevis Jones, 1875.

[Jones 1875 emend. Dakin 1906]: The genus Ramulina of Rupert Jones, 1875, is defined by Brady in the “Challenger Report” as follows: – “Test free, branching; consisting of a calcareous tube, swollen at intervals so as to form more or less definite, often irregular segments, from which lateral stolons or branches are given off. Texture hyaline.”

[p. 228]: The definition of the genus given by Brady was quoted above. I should suggest that this be now modified so as to read: – Test free, or adherent, branching and anastomosing; consisting of a calcareous tube, swollen at intervals to form more or less definite, often irregular segments (ampullae), opening into one another and being contiguous, or separated and connected by tubules. From these segments straight tubes (pipes) are given off. Texture hyaline or opaque.
