Here belonged also the extinct coal plants called Lepidodendron, Sigillaria, and Calamites. II. Bryophita, or Cellular Acrogens.

The molds, mildews, mushrooms, puffballs, etc. , which are variously grouped into several subclasses and many orders. The Lichenes or Lichens are now considered to be of a mixed nature, each plant partly a Fungus and partly an Alga.
