Pinaciophora is an amoeboid genus of uncertain affinity, previously classified as Rhizaria or the now-discredited Heliozoa.{{cite journal|vauthors=Yabuki A, Chao EE, Ishida KI, Cavalier-Smith T|title=Microheliella maris (Microhelida ord. n.), an Ultrastructurally Highly Distinctive New Axopodial Protist Species and Genus, and the Unity of Phylum Heliozoa|journal=Protist|volume=163|issue=3|date=2012|pages=356–388|issn=1434-4610|doi=10.1016/j.protis.2011.10.001|pmid=22153838 }} It has also been placed in Nucleariida,{{cite journal|last=Cavalier-Smith|first=Thomas|author2=Chao, Ema E.|title=Oxnerella micra sp. n.
