A thallose liverwort growing in and around a small waterfall. A flat, tongue-like liverwort with a distinct scale-like pattern to them. Very flat and has a few branches coming out the sides to from "Y" and "V" shapes with its body. Surface is somewhat rough to the touch. It has a single center vein that runs down the middle of its thallus that creates a visible indention on its back.
Habitat: Growing in an old growth conifer forest with many rocky outcroppings and waterfalls. Growing among mosses and maidenhair ferns under the dense canopy of Douglas-fir and western hemlock trees with an occasional western red cedar.
Weather: Misty, rainy, 60F, full overcast sky.
Alongside a stream.

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.
