crums crums crums is a proposed clade of microbial eukaryotes, whose name is an acronym of the following constituent groups: i) collodictyonids also known as diphylleids, ii) rigifilids and iii) mantamonadids as sister of the amorphea. it more or less supersedes varisulca, as ancyromonadida are inferred not to be specifically related to the orders diphylleida/collodictyonida, rigifilida and mantamonadida. crums collodictyon pseudopodoa scientific classification domain: eukaryota clade: opimoda clade: podiata clade: crumsbrown, 2018 orders collodictyonida rigifilida mantamonadida phylogeny opimoda ancyromonadida cavalier-smith 1998 emend. atkins 2000 malawimonadea cavalier-smith 2003 amorphea amoebozoa lühe 1913 emend. cavalier-smith 1998 obazoa breviatea cavalier-smith 2004 apusomonadida karpov & mylnikov 1989 opisthokonta crums mantamonadida cavalier-smith 2004 rigifilida karpov & mylnikov 1989 diphylleida cavalier-smith 1993
