Radula voluta
A liverwort you can spot from several metres away, thanks to it's bright green-ness illuminating otherwise shady ravines. It's smooth, close-knit leaves give Radula voluta a globulous appearance, making it difficult to differentiate the features of it's leaves. It's Nationally Scarce, occuring only in the very west of the British Isles, where the climate is mild and wet. It's always found on rocks and trees in burns, just above the normal water levels, so will be regularly inundated after rains.
The tricky thing about photographing this liverwort is it's glossiness, rather than it's size, as its actually quite large for a leafy liverwort (the fronds in the photo are about 2cm long). But trying to make the details of the plant stand out requires some severe underexposure to balance out the highlights.
