Abstract

We document the sporophyte of the extinct Frullania varians based on an inclusion in Late Oligocene Bitterfeld amber from Germany. The sporophyte consists of a short, ca. 45 μm thick seta that exceeds the perianth only slightly; the elongate-ovate, acute valves of the opened capsule are about 225 μm long, curved backwards and consist of an epidermal and an internal layer. Cell walls of both layers possess nodulose trigones. Several trumpet-shaped, unispiral elaters are fixed to the upper third of the internal valve layer. They have a length of ca. 150 μm and a diameter of 15-18 μm. A subglobose structure of 19 μm diameter is interpreted as a degraded spore. Fossil elaters and spores as well as capsule wall details of Frullaniaceae are described for the first time. ©2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
