When is a lichen not a lichen?
Chen et al. (2025) introduce a groundbreaking cyanobacterium-fungus symbiosis termed phyllosymbium, challenging traditional lichen concepts. In this unique association, the cyanobacterium envelops the fungus, displaying an unexpected structure. This discovery raises important questions about mutual benefits and interactions, broadening our understanding of symbiotic relationships in nature.
