Growing on the lowest, shadiest bank of a steeply graded seasonal stream, no doubt impressive during spring melt but just dripping at this season. The thalli seem more round than Pojar's oblong ribbons, but otherwise...dark green and shiny. Check; 4-8 mm. Check; unbranched or in pairs. Check; wavy edges. Check; small blisters at midrib. Check. Oak ferns/Gymnocarpium dryopteris growing out of it. Wonder how the spores of the fern got into the mat of liverwort and found a purchase. Water I'd guess.
It's the smaller liverwort in this picture. The bigger liverwort is conecephalum. I have found that when ever there is Conocephalem there is Pellia in the same patch.

Pretty sure I got this right. I know for sure I found Blasia on this road last year. There was so little here this year that I did not collect a sample.

Apparently this is the only genus of simple thalloid liverworts in California that has stems and leaves. That's confusing, no wonder I thought it was a leafy liverwort and keyed it out to Jungermannia.
The rhizoids are suppose to be purplish but they look more red to me.
I hate that I need to look at its spores to ID it to species.
Metzgeriales is an order of liverworts. The group is sometimes called the simple thalloid liverworts: "thalloid" because the members lack structures resembling stems or leaves, and "simple" because their tissues are thin and relatively undifferentiated. All species in the order have a small gametophyte stage and a smaller, relatively short-lived, spore-bearing stage. Although these plants are almost entirely restricted to regions with high humidity or readily available moisture, the group as a whole is widely distributed,...
