rambryumDescription
Seems like Nardia compressa but wrong habitat and huge leaf cells. Also seems like Mylia taylorii but on wood over rock face and botryoidal oil bodies. Mystery.

amanda_hDescription
Sporophytes are 1-2 cm tall, thallus very irregular and hard to measure maybe a few millimeters wide. Tubers seem to be arising along margin and at apex. Spores are brown and have warty bumps on the distal surface. And there are these funky boney like things along with the spores that I'm guessing are pseudoelaters.

wendy5Description
I was excited to find such a cool liverwort along the Pony Bridge trail! There were hundreds of these a couple of miles from the beginning of the trail in the temperate rainforest. My field guide calls Conocephalum conicum "Snake Liverwort" and this site calls it Great Scented Liverwort. I wish I'd tried smelling it.

Hard Shield Fern (Polystichum aculeatum)Observer

PrivateDescription
There are 4 mysterious specimen of shield fern, Polystichum sp., obviousely falsly identified as P. andersonii preserved at:
Muséum national d’Histoire naturelle, Paris (France)
Collection : Vascular plants (P), Specimen P01493097 to P01493100
The leaves are very similar to European P. aculeatum, so i suspected for a while, the collector W.N. Suksdorf (born in Germany) might have introduced it to Washington, US.
P01493097 and ....98 referring to this report are labelled: Washington's Flora. Klickitat County. Aspidium aculeatum Sw. var., in sylva montis, Bingen, W.N. Suksdorf VIII 07.
The German Gardener and collector E.M. Reineck was in contact with Suksdorf and shall have got specimen from Washington, USA by him.
The herbarium P got both sheets from Reineck on 8th September 1910 as visible upon stamps.

http://coldb.mnhn.fr/catalognumber/mnhn/p/p01493100
Unfortunately the collection's location is given very unprecisely, it could as well be identic with the sample of the year after (....99 + ....100).
This specimen could be big grown P. californicum with nearby fully bipinnate fronds, or some luxurating hybrid, i guess rather with P. braunii than andersonii.
It deviates from typical P. californicum in clearly shortened lowest pinnae, seeming more obtuse in some cases.
