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.

While the terminology of the units has still not been fixed, researchers mostly followed the procedures of the Braun-Blanquet approach: studied releves and described floristically delimited units for the thallophyte vegetation using the rank-indicating terminations of the ICPN (-etum, -ion, -alia, -etea).
The extensive number of already described thallophyte syntaxa shows that construction of a meaningful syntaxonomic system for the thallophytic vegetation is feasible (see also WILMANNS, 1998).
In Pringsheim's (1876b) experience, the first neutral generation of thallophytes (i.
Homologous alternation occurred in most thallophytes and "might be described as a mere differentiation--often a very slight one--of successive gametophytes.
