Read about Thallophyta in the Standard Cyclopedia of Horticulture
Plants characterized rather indefinitely by the absence of an archegonium around the egg, and the absence of the type of antheridium found among the higher plants. The plant body is rarely differentiated into organs simulating stem and leaves, and no true vascular tissue is found in the group. Formerly the Thallophyta were divided into the Algae, Fungi, and Lichens; but this, though a good classification on physiological grounds, does not indicate actual relationship so well as the modern division into fifteen classes founded on structure, as follows: CLASS I. BACTERIA CLASS II. CYANOPHYCEAE (Blue-green Algae) CLASS III. FLAGELLATA (Flagellates) CLASS IV. MYXOMYCETES (Slime Molds) CLASS V. PERIDINEAE CLASS VI. CONJUGATAE CLASS VII. DIATOMEAE (Diatoms) CLASS VIII. HETEROCONTAE or CONFERVAE CLASS IX. CHLOROPHYCEAE CLASS X. CHARACEAE (Stoneworts) CLASS XI. PHAEOPHYCEAE (Brown Seaweeds) CLASS XII. RHODOPHYCEAE (Red Seaweeds) CLASS XIII. PHYCOMYCETES CLASS XIV. EUMYCETES CLASS XV. LICHENES (Lichens) The above text is from the Standard Cyclopedia of Horticulture.
