Photobionte lichen
WebIn many lichens the apothecial margins are composed solely of fungal tissue (typically different from the paraphyses and asci of the hymenium) though there are also many species in which the apothecial margin bears an extra layer, composed of fungal and photobiont cells, derived from the thallus and here we refer to a thalline margin.
