The lichen algaTrebouxia: does it occur free-living?

Plant Systematics and Evolution Aims and scope Submit manuscript

Abstract

Recent evidence indicates that the most common photobiont of lichens,Trebouxia, has evolved from the soil algaPleurastrum terrestre. The fewTrebouxia cells that have been seen in unlichenized condition probably were released from asexual propagules or thallus fragments.Trebouxia appears to be a lichenized form ofPleurastrum and does not exist free-living.
