[2] It grows in patches in damp, sheltered places on neutral or acidic substrates.

[3] The thalli are irregularly branched and are fairly large, growing to over 1 cm wide and several centimetres long.

[4] Pellia epiphylla is monoicous, with both male and female sex organs on the same thallus.

The male sex organs (antheridia) absorb moisture and burst, releasing sperm.

The sperm swim towards the female sex organs (archegonia) and fertilise the ova.
