The growth form and colour of Hymeniacidon perlevis varies depending upon shore exposure, from thin sheets on lower to mid shore (growing along crevices and fault lines), to massive flanged or turreted forms often found on the lower shore in wave sheltered locations and in the sublittoral where conditions are distinctly silty. Colour varies from yellow to orange to blood-red. Shore forms tend to be blood-red, whilst sublittoral forms tend to be pinkish-red.
In the intertidal and shallow sublittoral more than one form can be detected, which may eventually be recognized as including more than one distinct species.
Hymeniacidon kitchingi is the only other Hymeniacidon species from Western Europe. It is more thinly encrusting than Hymeniacidon perlevis, and is beige-yellowish in colour. Close examination of the spicules of the endoskeleton may be required to distinguish other species.
