Metzgeria furcata, the forked veilwort,[1] is a frequent liverwort growing on the bark of a wide range of tree and shrub species and occasionally on rocks.

[2] It is a slim, translucent thallose liverwort that forms yellow-green mats of branches about 1mm wide.

The defining characteristic is definitely the fact that the thalli and the midrib fork at the end, which is visible on most patches.

The Forked Veilwort rarely makes sporophytes, although on the underside of quite a few patches an inflorescence can be found.

[3] Apometzgeria pubescens is very hairy and Metzgeria fruticulosa and M. temperata constantly have gemmae on the thalli.
