Protist both microbial eukaryotes and macroscopic organisms that do not fit into the other traditional kingdoms. In cladistic systems (classifications based on common ancestry), there are no equivalents to the taxa Protista or Protoctista, both terms referring to a paraphyletic group that spans the entire eukaryotic tree of life. In cladistic classification, the contents of Protista are distributed among various "supergroups" (SAR, such as protozoa and some algae, Archaeplastida, such as land plants and some algae, Excavata, which are a group of unicellular organisms, and Opisthokonta, such as animals and fungi, etc.). "Protista", <nowiki>"Protoctista"</nowiki> and "Protozoa" are considered obsolete. However, the
Clavarioid fungi on wood or on decaying herbaceous stems and fallen leaves. Some species, particularly in the genera "Clavulina" and "Ramaria", are known to be ectomycorrhizal (forming a beneficial association with the roots of living trees). Species in the genera "Ertzia", "Multiclavula", "Lepidostroma", and "Sulzbacheromyces" are lichenized and grow in association with algae. Clavarioid fungi have a worldwide distribution, though some genera—such as "Aphelaria" and "Lachnocladium"—are principally tropical. They are one of the most common of the four fungi groupings. Clavarioid fungi The clavarioid fungi are a group of fungi in the "Basidiomycota" typically having erect, simple or branched basidiocarps (fruit bodies)
