Original description: [Cookson and Eisenack, 1958, p. 48]:

Description:
Shell elongate-oval, membrane thin, firm, smooth with 4-6 approximately longitudinal rows of evenly-spaced, solid processes which are connected with one another both proximally and distally by short threads to form a rather small meshed superficial network. Short spine-like outgrowth are sometimes present on the connecting threads. In the holotype, a pylome appears to be present at one end of the shell.

Dimensions:
Type - 90x62 µm overall; shell - 62x35 µm; range - 90-109x57-71 µm overall; shell 62-85x28-52 µm.

Affinities:
C. mirabilis is distinct from all known species of Cannosphaeropsis in the elongated form of the shell.
