I send you a Word document with my find on juncus.
Is my determination correct? I have my doubts. In Breitenbach(vol. 1 p. 146) it should be stalkless but taking into account the taxonomic corrections the determination is correct! Ellis and Ellis p.498 confirms my conclusion, so am I right or am I wrong.
Thanks in advance, kind regards,

R. calopus is usually stalked. Your photo of an apically opened ascus in IKI shows a distinct bluing. Now important would be the ascus base. Did you see young asci emerging from the basal cells? Are there croziers or not?
There is a quite sharp delimitation between Poaceae (with croziers) and Cyperaceae/Juncaceae (without). From the substrate yours should be R. paludosa (or R. henningsiana which seems to be the older name).
There is a recent paper on this, by F. Pancorbo, Miguel-Angel Ribes et al. 2013.

Thanks for your quick response, unfortunately I have no more material to investigate. I add some pictures, but I suspect they do not bring clarity.
In any case, many greetings,
François
I am sending you the paper.
Good luck.
It is so nice to have friends...so far away... Many thanks for your help!
I revisited the site and with some difficulty discovered that the substrate is not Juncus effusus but Eleocharis palustris(Cyperaceae).
According to Bernard Declerck it's the first time that Rutstroemia paludosa was found in Flanders.
Kind regards,
François
I checked the collection received from François. The asci have indeed no croziers, only a basal bent protuberance.
I am interested in receiving the Pancorbo & al. paper too. Thanks in advance.
Best regards,
Bernard
