Brief Report


Light microscopical observations on mitosis in living material of the amoebal and plasmodial phases of the MyxomyceteEchinostelium minutum de Bary (orderEchinosteliales) are reported for the first time. The uninucleate amoebal cell undergoes centric, open spindle mitosis whereas the multinucleate plasmodium exhibits acentric, closed spindle mitosis.
