Autozooecial diaphragms rare to absent. Hemisepta absent. Pustules common along autozooecial boundaries, scattered in exozonal walls. Metazooecia polygonal to irregularly subcircular, arranged in groups, singly or in short rows. Monticules common, generally flat; consisting of metazooecia, few autozooecia and some skeletal material.

COMPARISON
The genus Pseudostictoporella Ross, 1970 differs from the genus Stictoporella Ulrich 1882 by the absence of hemisepta, from the genera Oanduella Männil, 1958 and Stictoporellina Nekhoroshev, 1956 – by bifurcating colony shape instead of reticulate one in the latter genera.
