Black oats ID help?

[Doro]

I just got this little seed sample in a trade. It's labled as an old landrace of black oats from South Karelia, Finland.
Sadly I have no experience with oats and the term black oats is used for Avena sativa and Avena strigosa in Swedish. Some darkness to hulls or seeds seems to be enough to call it black oats, so now I'm confused.
Am I right in thinking this should be Avena strigosa?
Or could primitive Avena sativa cultivars look similar?

The picture is not helping.
Does the comparison in section Morphology in feedipedia help?

Hmmm I still can't tell. I guess I will have to wait until summer and look at the plants.

Maybe I'll grow some naked oats at the side, if they cross it can't be Avena strigosa.

I don't know what kind of oat that is, but it's definitely not ergot infected, otherwise it would have a puffy appearance.
