Dear all,
Manfred Rösch found a pollen we don’t know:
Unknown pollen type from Mindelsee, depth 36 cm, age about 17. century A.D.
Size 40μm, oblate, suprareticulat, mesh width 2-3 μm, colpi very short, intercolpia concave, similar as with spores of Cryptogramma crispa
And see also the images.
Does anyone know this?
Many Thanks
Elske
