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
