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.

The status of the thallophyte communities has been discussed in detail by expert vegetation ecologists familiar with vegetation at different scales (WILMANNS, 1966; BARKMAN, 1973).
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).
Pringsheim (1876b) presented a contrary interpretation of the connection between alternation of generations in thallophytes and mosses.
In Pringsheim's (1876b) experience, the first neutral generation of thallophytes (i.e., the spore-producing thallus that develops from the fertilized egg) often proceeded directly to spore-production, with greater or lesser suppression of the vegetative parts relative to subsequent neutral generations.
