The observed combination of character states is not present in extant crown group lineages of Frullania. A syninclusion in one of the amber pieces is interpreted as a detached gynoecium of a second Cretaceous Frullania species and is described as F. baerlocheri, sp. nov. The subgynoecial underleaves of the syninclusion are suborbicular in shape, and allow for a separation of this species from F. cretacea. The described amber inclusions are the oldest representatives of an extant genus of leafy liverworts known so far.
