Locality and horizon.

Remarks.
All specimens are in good accordance with the type and previously described material (Suppl. material 1: Figs S3-S5; compare descriptions in Heinrichs et al. 2017a; Feldberg et al. 2021b) and show the characteristic helmet-shaped to campanulate Frullania -type lobules which are often large in relation to the lobes (Suppl. material 1: Figs S3D, S4F, S5B, D, F). As in previously investigated material, the form of the underleaves is very heterogenous ( Feldberg et al. 2021b). Most are elongate rectangular to strap-shaped and taper progressively towards the apex (Suppl. material 1: Figs S3D, S4B, S5B). Below the apex they are usually somewhat increasing with the uppermost sector being obtriangular or irregularly rounded and often carrying rhizoid bundles and marginal teeth or cilia. Some underleaves on main shoots and occasionally also on primary branches are ovate to obovate to rectangular with the widest part in the middle and often less prominent cilia (Suppl. material 1: Figs S4F, S5F). One specimen (BuB4334) has a very distinct flagelliform branch (Suppl. material 1: Fig. S3E).
