Thallophyte

a lower plant (an alga, fungus, or lichen) whose body is not divided into stem and leaves but consists of a thallus. (A plant whose body is divided into stem and leaves is a cormophyte.) Some algae, for example, Caulerpa, Macrocystis, and Sargassum, are externally differentiated into stem and leaf organs, but the anatomic structure of these organs is less complex than in higher plants.

thallophyte

any plant of the group (or former division) Thallophyta, containing the most primative types of plants characterized by the possession of a THALLUS. They vary in size from unicellular types to giant seaweeds up to 75 m in length. The group includes Algae, Bacteria, Fungi, slime fungi (Myxomycetes) and lichens. The Thallophyta clearly have several different evolutionary origins and the term is not used in modern systematics.
