genome typing. Fungi belong to the domain Eukarya and kingdom Fungi,
and they can be classied into six divisions:
Ascomycota
Basidiomycota
Chytridiomycota
Glomeromycota
Microsporidia
Zygomycota
DNA testing has also led to revisions in the branching fungal phylogeny
(Palaeos 2008; Wang et al. 2009). Even with modern DNA testing, there are
many fungi incertae sedis (Latin for uncertain dwelling place), which defy
phylogenetic classication. Although fungi are eukaryotes, their cell walls
are composed of glucans and chitin; fungal cell walls do not contain cellu-
lose, as found in plant cells.
Fungi may be classied as benecial to human sustainability if they are
edible, or ...
