ABSTRACT=<p>An analysis of the phylogeny of Cephaloziellaceae was carried out based on trees constructed for previously and newly obtained sequences of five genes: nuclear ITS1–2 and chloroplast <italic>trn</italic>L–F, <italic>trn</italic>G, <italic>rbc</italic>L, and <italic>psb</italic>A. Phylogenetic trees inferred from different genes are congruent for the main details; however, the position of several taxa is variable. As a result, a new phylogenetic system of the family was proposed. The narrow genus concept seems to be more appropriate for the family. <italic>Cephaloziella spinicaulis</italic> is segregated into the new genus <italic>Douiniella</italic>, the generic status for <italic>Prionolobus</italic> and <italic>Metacephalozia</italic> is confirmed, and the dubious generic status of <italic>Kymatocalyx</italic> is substantiated. The generic independence of <italic>Cylindrocolea</italic> from <italic>Cephaloziella</italic> s. str. is confirmed. The small amount of data hinders the description of two more genera from <italic>Cephaloziella</italic> s.l.</p>
