High Point State Park, on rocks near the monument. I def think it's a Polytrichum.... The capsules seem too long to be commune/juniperum, and they also seem to lack the required disk. Doesn't feel like it's commune in general. The capsules for pallidisetum are described as tan, but seem red in LOTS of photos, esp the one in the Princeton Field Guide to Mosses, and many of the traits match descriptions within said field guide (such as red tipped leaves; boxy & bent over capsules). Actual experts pls help

The Hepaticae and Anthocerotae of North America by Rudolf Schuster (vol. 2, 1969) describes this liverwort as “An extraordinarily widespread species…with truly ‘weedy’ propensities,” but this observation of Isopaches bicrenata is only the fifth recorded in iNaturalist for all of North America. Although common, it’s inconspicuous and apparently unnoticed.

Seeds dimorphic. 1.5-2mm or so. Would like to hear some opinions on this confusing genus/species. Keys out to rolandii better than any other species. Location is general since it's rare.
