Halgerda brycei is similar to Halgerda carlsoni with large, orange-tipped tubercles covering the dorsum, but H. brycei lacks the small spots between the tubercles. In fact there are no other orange markings on the mantle. It also differs from another similarly coloured species, Halgerda batangas, which has a fine, orange network between the orange-tipped tubercles. Halgerda brycei has translucent white large, sparsely pinnate gills which are lined with black. The rhinophore clubs are black and there is a line of black specks up the posterior midline of the rhinophore stalks. Halgerda carlsonilacks this dark line and H. batangas has dark spots on the anterior of the rhinophores. Another similar species, Halgerda stricklandi has a yellow rhinophore club with similar orange tubercles on the dorsum. This species is named after Clay Bryce of the Western Australian Museum
