Fragments of a sterile Plagiochila were found in a piece of Baltic amber along with the moss Trachycystis flagellaris (Sull. & Lesq.) Lindb. They are described as Plagiochila groehnii Grolle & Heinrichs, sp. nov., and compared to the extant Plagiochila sciophila Nees & Lindenb., a morpologically closely related species from southeastern Asia.
