Short summary
A revision of amber fossils assigned to Cylindrocolea dimorpha has yielded evidence of the presence of underleaves, which have not previously been reported for this species and conflict with the current circumscription of the family. We transfer the fossil species to Odontoschisma and propose the new combination O. dimorpha. Our reclassification concurs with hypotheses on the divergence times of Cephaloziaceae derived from DNA sequence data.
