Haircap moss

Description:

A common moss. Leaves are toothed, as shown in the first picture. The sporophyte plant grows out of the archegonium of the gametophyte plant as shown in the second picture. The mature sporophyte eventually loses its cap, allowing it to release spores.

Habitat:

Moist woods, typically growing on soil rather than rock.

Notes:

The flat, toothed leaves are consistent with this moss being a member of the Polytrichum section of the genus rather than the Juniperifolia section.
