Probably not Homalothecium...
I keyed this to L. californicum in the field, but I don't think that's right. L. dasycarpum? This whole family throws me.
I was interested in the white whispy one, still not sure what it is. Not that I know what the other one is either, mind you.
Same mystery one I saw in Marin a few weeks ago. It seems to have the tuber-like base to the sporophyte like (I'm told) Phaoceros is supposed to have, but it's definitely way different than the ones without frilly leaves like this.
Nice to see the sporophytes again.
Orthotrichum has neat capsules. Some day I'll get a good shot of them.
C. cuneatus, I presume?
Not sure. Brown on back, none of the blue or red of a kestrel, pits were sort if dark but not as dark as I've seen in others.
Base of bay with Alsia, Dendrialsia, Isothecium, Porella, turret spiders
