Note 11 — INTRODUCTORY
Reading edition
Researches of Olive, Trans. Wis. Acad. Sci., Arts and Let., XV., Pt. 2, p. 771, and of Jahn, Ber. d. Deutsch Bot. Ges. XXVI., p. 342, and XXIX., p. 231, demonstrate synapsis, and accordingly some form of alternation among the slime-moulds. From the protracted and painstaking investigation of the German author it appears that in Didymium at least, and probably Badhamia synapsis immediately precedes spore-formation as in Ceratiomyxa; that the amœboid issue of the spores are haploid; the nuclei of the plasmodium, diploid; that the ordinary vegetative plasmodium is accordingly sporophytic. That is, the sporophytic phase is dominant, as in higher plants.
