Original description as Cannosphaeropsis aemulum ssp. integrum: [Cookson and Eisenack, 1958, p. 47]:

Diagnosis:
Shell sphaeroidal with a number of hollow, funnel-like processes the wall of which are, for the most part, entire or only slightly perforated. The "funnels" are connected by short delicate threads.

Dimensions:
Overall diameter 95-128 µm, processes 24-38 µm.

Affinities:
The subspecies integrum is readily distinguishable from the typical examples of C. aemula by the rather shorter, broader and more entire processes.
