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).
This fern is endemic to the Hawaiian Islands. Sighted occasionally in this wet rain forest of 240-250 inches/year. Elevation around 3200ft/976m. Note numerous sporangia on lower surface of this fertile blade.
This fern is endemic to the Hawaiian Islands. Blade color at time of observation was lighter than typical, perhaps due to age. Indusia are absent. Dark brown scales observed at base of stipes. Elevation in photo: 3820 ft.
