Crossidium squamiferum plus...

Description :

The moss with very long hair points to the leaves (including the plant with the green capsule) is Crossidium squamiferum. Also present are Bryum argenteum (eg near the top, left of center, and the silvery plants to the right of the Crossidium patch); Aloina sp. (two plants with narrow, dark green leaves with incurved margins towards the upper right) and many plants with triangular yellow green leaves that I'm guessing are a Didymodon species (possibly also a second species with larger leaves) - comments welcome. Photographed in situ on a steep south-facing open grassy bank with rock outcrops, in a small valley just west of the north branch of Cache Creek south of where it crosses Highway 20, Lake County, California.
