Poa nemoralis is an alien grass that appears capable of becoming an invasive species in some forests in Wisconsin. The culms are obviously clumped and the leaves spread horizontally. Also, I don't have the technical resources to reproduce it on the web page, but the rachilla is clearly pubescent within each spikelet. I have not seen the rare native Poa interior which is similar, but Poa nemoralis has very short ligules-- about 0.3 mm in the photos above (much shorter than in the native Poa interior) and leaves tend to continue farther up the stem that they do in Poa interior.

I have seen serious infestations of this grass in Forest, Oconto and Door Counties, but I suspect it is much more common than the record of vouchers indicates.
