2 photos of Asplenium ceterach found in my hometown this month,
the species is extremely rare here in the northern part of Germany.

Wonderful pictures Gerd, I love to see it walking it's way along a wall in all the cracks and crevices.

Thank you Shelag! This occurence was nearly lost when the owner 'tiedied up' the wall. Fortunately he did this not very carefully
and the ferns sproutet again from their roots. After that the propietor was informed about the uniqueness of the site and so these
plants are relatively safe now.

I am wondering about identity of this fern.
I have bought it as Dryopteris dilatata 'Stansfieldii', but can't find anything with that in internet. Maybe it is something else? Any ideas?
It is not big, maybe 20-25cm tall, and it loses it's leaves during winter, so that in the spring there are no leaves left.
The first picture was taken in September and the last picture last week.

Here is finally a picture of it's leaves now, and spores. Not a very good picture, I'm afraid. I will have to take a better one next summer.
I tried to compare it with my D.dilatata 'Whiteside' spores, but 'Whiteside' leaves had already died so I couldn't compare.

Leena, the spores look like those of D. dilitata. If the scales on the stems have a dark line down the centre this is also a feature of D. dilitata. The RHS Plant Finder 2019 lists Dryopteris dilitata Crispa Whiteside. I hope this helps.

Thank you Ian.  :) It seems that it is D.dilatata 'Stansfieldii' like the label said, though I can't find 'Stansfieldii' in the net.
It is a small fern (20-25cm), contrary to 'Whiteside' (or is it possibly 'Crispa Whiteside' like Ian wrote), which is a tall fern, maybe 80cm or close.
Here is a picture of my D.dilatata 'Whiteside' last July.
