Fruiting bodies (sorocarps) tend to be clustered or grouped in groups 1 to 3 and solitary in group 4, while branched structures are also more common in the basal groups. Specific branching patterns do not show strong group-specific trends and laterally branched, rosary-type and whorled morphologies appear, respectively, six, two and five times across the tree. There is a modest trend towards taller sorocarps in the more-derived members of groups 1-3, and a very strong trend towards sorocarps with long thick stalks and large spore heads (sori) in group 4. These large sorocarps are usually buttressed by cellular support structures, such as basal disks and supporters. The crampon-base is almost uniquely associated with a tight cluster of group 3 species.
