This exactly the species! You only did not test IKI, or? Ah, now I found your remark.

The host can easily be determined. Have a look at a cross break of the stem, the structure of Urtica is unique.

I assume you do not have the possibility to take a sequence? There is only a fragment of ITS.

Here are the cross cuts.

Regarding the sequence - no, I don't, for now.

Yes, especially the third photo is characteristic. See examples. I know no other herb with this appearance.
