What does thallus mean?
A thallus is the vegetative part of a plant, such as a fern or a liverwort, that grows from a single point and is not differentiated into roots, stem, and leaves. It is a flat or branching structure that produces new plants.
Example
"The thallus of the liverwort was a flat, green sheet that covered the rock."
