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

Ancient sources 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 Isaiah 45:7 that God did not create evil, the exact nature of the of Colluthus is not known. His activities after 324 are similarly obscure.
