Marine life from 10 million to 14 million, of which about 1.2 million have been documented and over 86 percent have not yet been described. Microorganisms constitute more than 90% of the marine biomass. A microorganism (or microbe) is a microscopic living organism, which may be single-celled or multicellular. Microorganisms are very diverse and include all bacteria, archaea and most protozoa. This group also contains some species of fungi, algae, and certain microscopic animals, such as rotifers. Many macroscopic animals and plants have microscopic juvenile stages. Some microbiologists also classify viruses (and viroids) as microorganisms, but others consider these as nonliving. In
Clavarioid fungi Clavarioid fungi The clavarioid fungi are a group of fungi in the "Basidiomycota" typically having erect, simple or branched basidiocarps (fruit bodies) that are formed on the ground, on decaying vegetation, or on dead wood. They are colloquially called club fungi and coral fungi. Originally such fungi were referred to the genus "Clavaria" ("clavarioid" means "Clavaria"-like), but it is now known that clavarioid species are not all closely related. Since they are often studied as a group, it is convenient to retain the informal (non-taxonomic) name of "clavarioid fungi" and this term is frequently used in research papers. "Clavaria" was
