The test, or shell, may be trochospiral to planispiral throughout, or just in the early part with the later part uncoiled. Chambers may be somewhat enveloping, and attached forms may uncoil in the adult. In coiled forms, the aperture is interiomarginal, or terminal in uncoiled forms. The test wall is of perforate hyaline (glassy) oblique calcite, appearing optically granular.

gollark: There are 10 of them, look.
gollark: Also, we don't have evidence now, unless we go back a lot, but R10's new wording is recent and I doubt you would be in favour of retroactively punishing things.
