SUMMARY Study of the apical portions of vegetative thalli of 21 species of the genera Gelidium and Pterocladia (Gelidiales‐Rhodophyta) revealed the existence of six patterns of medullary structure. Each pattern is characterized by the organization of the medullary tissue and the changes in cellular dimensions from apex to subapex. These characters can be used to separate groups of species within each genus.
