Copious mats of it in a shady patio garden
No interactions present.
The BBS guide says of Pellia epiphylla "the surface lacks an angular network of cells visible on the surface of the thallus".
I think I can see such a network.
Thanks, everyone. I'm struggling a bit with these common liverworts.
My money is now on Marchantia for this one, comparing it with an earlier sighting of mine.
My understanding was that Pellia doesn't have a cell network over its surface, based on this observation, though I've also got this one, which could also be a Pellia, but is colouration is completely different.
Any guidance gratefully received. Thanks
