Symphyogyna hymenophyllum is dendroid in habit. The thallus consists of an erect 1-2 cm tall reddish-brown stalk that terminates in an expanded fan-like portion 1 cm long by 2 cm wide consisting of several segments with toothed margins. The dorsal surface of male plants has rows of scales along the midribs, each covering a sperm-containing antheridium. The dorsal surface of female plants has one or more scales at the fork of a midrib, each covering a group of egg-containing archegonia.
Widespread throughout New Zealand in damp forest.
