On a stump in the meadow toward the end.
Someone was calling this one "Mickey Mouse hands" which is definitely memorable, though I don't recall Mickey having claws. Demonic Mickey Mouse Hands?
This is the only species in this genus in California according to Doyle & Stotler, so I guess if you can find the little hands, you know what you've got.
Showing red coloration.
Growing on a shady, mossy stream embankment, maybe 10 ft up.
Ventral leaves not folded on all sides, closely packed.
Maybe Frullania again? What are the big reddish round things that look like fruit?
Another population of Lunularia that forms sporophytes! Ken was quite pleased.
Maybe a hornwort. Growing among the Lunularia by the spot where we had lunch.
