Fungi are heterotrophic organisms that disperse forming spores. Energy is stored as glycogen (not as starch, as in plants). Generally the cell was does not contain cellulose but rather chitin. Formerly fungi were considered a branch of cryptogamic plants. Presently is is obvious that “fungi” comprise an array of phyla, with unclear mutual affinities.
