It looks like Rytidoserma Monti cola from the CNM grasses guide

Monticola

It could be. Both species are very similar with the main distinguishing features being the size of the lemma body (up to 3mm in R. monticola and >3mm in R. erianthum). My suggestion is tentative and I would like a second opinion before I make a confirmation.

I could take a measuring device although I’m not sure I could find the right clump of grass. Hopefully someone will call it one species or another. Thanks!

I agree with Matt's suggestion, however hopefully our friend Grassman can enlighten us.

Apart from lemma length, setae tend to be quite short in monticola (2-4mm) compared to erianthum (about 6mm), so without a lemma length I'd support R erianthum, as these setae are long
