A schismatic presbyter in during the episcopate of ALEXANDER (312-326), nineteenth patriarch of the See of Saint Mark. In 324 the council convened by Hosius to quell the growing Arian deposed Colluthus for taking upon himself the episcopal function of conferring orders.

Ancient indicate that Colluthus was not a supporter of Arius, but was himself the leader of a schismatic group. Although Philastrius stated that Colluthus erred in against 45:7 that God did not create evil, the exact nature of the beliefs of Colluthus is not known. His activities after 324 are similarly obscure.
