Discussion:

Anacystis amplivesiculata is a very distinct and beautiful species, with the spherical, bright bluish-green cells set in a clear, opalescent matrix, and with resting spores surrounded by a distinct, hyaline, papillate wall. Frequently the cells of an entire colony divide simultaneously just before spore formation and the spore wall begins to form at the beginning of division.
