Identification notes
Be prepared to get wet to find this lovely liverwort, for it often grows in dark, dripping places, especially in flushed recesses by waterfalls where it may be accompanied by the likes of Fissidens rivularis and Conocephalum conicum.
No other liverwort looks like it, although if you examine the underside of a shoot, the resemblance to Frullania is obvious in the small lobules that look a little like old-fashioned policeman’s helmets.
If you are fortunate enough to come across a large population, its fan-like growth form is usually obvious.
