(Pellia neesiana)
P. neesiana is vegetatively very similar to P. epiphylla with thalli about 1 cm wide, although it has a greater tendency to develop reddish or purple tints and has a sharp, aromatic smell. It is dioicous, with separate male and female individuals. Females develop a short, vertical tube of tissue around the sex organ. This tube is not closely toothed at its mouth.
