(buy-o-mix-a) is a genus of poorly known amoebae. Some think that all organisms with branching pseudopodia should be assigned to the unshelled (athalamid) granuloreticulosea. However, it is quite clear that many different kinds of organisms have adopted fine branching pseudopodia - such as Massisteria
known to be a cercomonad, vampyrellids such as Arachnula
, nucleariid filose amoebae and so on. In Biomyxa
the pseudopodia are stiffened internally, they branch but rarely join back together. the pseudopodial system is very dynamic, with stiff elements being formed quickly and breaking down quickly - with the cells almost crawling across the substrate. Phase contrast.
