Lichens are the symbiotic outcomes of open, interspecies relationships, central to which are
a fungus and a phototroph, typically an alga and/or cyanobacterium. The evolutionary …

The class Trebouxiophyceae is comprised of coccoid to ellipsoid unicells, filaments, blades
and colony-forming species of green algae occurring in diverse terrestrial and aquatic …

Abstract Background Lichens, encompassing 20,000 known species, are symbioses
between specialized fungi (mycobionts), mostly ascomycetes, and unicellular green algae or …

Melting snowfields in polar and alpine regions often exhibit a red and orange colouration
caused by microalgae. The diversity of these organisms is still poorly understood. We …

Lichens provide valuable systems for studying symbiotic interactions. In lichens, these
interactions are frequently described in terms of availability, selectivity and specificity of the …

The current literature reveals that the intrathalline coexistence of multiple microalgal taxa in
lichens is more common than previously thought, and additional complexity is supported by …

Chlorella and Stichococcus are morphologically simple airborne microalgae, omnipresent in
terrestrial and aquatic habitats. The minute cell size and resistance against environmental …

Symbiosis plays a fundamental role in nature. Lichens are among the best known, globally
distributed symbiotic systems whose ecology is shaped by the requirements of all symbionts …

Coccomyxa is a genus of unicellular green algae of the class Trebouxiophyceae, well
known for its cosmopolitan distribution and great ecological amplitude. The taxonomy of this …

We present a synopsis of studies reporting the free-living occurrence of green algal lichen
symbionts. We give an overview of all known lichen photobiont genera together with …
