This moss is rare in California and was growing in patches on wet rock, mostly in sheltered recesses but in an open section of the Feather River Canyon, interspersed with patches of with Mielichhoferia elongata. The moss was seen in the field on March 26th, this is an image taken at home few days later from a small piece.

F. grandifrons = the darker patches in and to the right of the right-hand waterfall

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).

Endemic to Hawaii and only known from a single area near Kilauea volcano. Similar to S. ligulata from North America. Unusual in Hawaiian plants with its' tolerance to high temperatures and high concentrations of mercury (Mashuri Waite, 'Mosses of Hawaii Volcanoes National Park', Univ. Hawaii Manoa,Pacific Cooperative Studies Unit, Tech. Report #153, Oct, 2007)
