The erect colonies of Lafoeidae may be divided into two basic kinds, according to the arrangement of the fascicular tubes and their branching. Although these two types were first noted by Allman (1888), subsequent authors gave little or no attention to their distinction ( Marques et al. 2006). Acryptolaria differs from Grammaria in this character, the colonies of the former having a central axis from which all primary branches arise, the fasciculation being complemented by additional tubules with no branching. In Grammaria , however, the fasciculation is composed of many tubes from any of which the primary branches arise.

Although we consider that two categories of nematocysts characterized the species of Acryptolaria (large putative macrobasic mastigophores and small putative microbasic mastigophore), only one category could be observed in a few species because of the almost complete absence of coenosarc in the type material examined and/or all the material was mounted in microslides.

As shown above, many species currently assigned to Acryptolaria were originally described in the genus Cryptolaria , but both genera are easily distinguishable by the presence of nematothecae in the latter.
