WebMycobionts in the temperate region are consistently associated with a specific photobiont lineage. We therefore conclude that a photobiont switch in the past enabled C. aculeata to colonize temperate as well as polar habitats. Rare photobiont switches may increase the geographical range and ecological niche of lichen mycobionts by associating ... WebAbstract. Lichens are dual organisms formed from a symbiotic association of a fungus, the mycobiont, and an alga and/or cyanobacterium, the photobiont, in which numerous photosynthetic cells are intertwined in a matrix of fungal hyphae. Such definitions raise the question as to whether lichens are technically individual organisms.
