[7] The following germination periods are furnished by Dr. Constantineanu (_Inaugural Dissertation ueber die Entwickelungsbedingungen der Myxomyceten_; Halle, 1907). _Reticularia lycoperdon_ 30 to 60 min. _Fuligo ovata_ 30 to 90 min. _Stemonitis splendens_ 5 to 6 hrs. _Perichaena depressa_ 5 to 8 hrs. _Amaurochaete atra_ 6 to 10 hrs. _Arcyria incarnata_ 8 to 10 hrs. _Lycogala epidendrum_ to 60 hrs. _Physarum didermoides_ 1 to 10 da. _Dictydium cancellatum_ 1 to 20 da. These records are for sowings in drop cultures, in distilled water, kept at temperature of 65 deg.-70 deg. F. (18 deg.-20 deg. C.). Our own experiments have been made both with distilled water and tap-water with the advantage in favor of the latter. _Dictydium cancellatum_ germinates in tap-water at temperature 70 deg.-80 deg. F. in 12-15 hours fresh from the field. _Fuligo ovata_ spores were all swarming in about one hour at the same temperature. Jahn (_Myxomycetenstudien; Ber. der Deutschen Bot. Ges._ Bd. XXIII., p. 495) finds that the germination in some cases as _Stemonitis_ species, is hastened by wetting, then drying, then wetting again. Pinoy thinks microbes aid in germination (_Bull. Soc. Myc. de France_ T. XVIII.). [8] The plasmodium in this case chances to be red, scarlet, etc. [9] "Die Myxomyceten sind ebenso den Pilzen wie den echten Thieren verwandt."--Rostafinski; closing sentence of the _Versuch_, thesis for his doctorate at the University of Strasburg, 1873. [10] _Botanical Gazette_, XVII., pp. 389, etc.; 1892. [11] 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 amoeboid 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. [12] Cf., 1884, _Ver. Morph. u. Biol. der Pilz. Mycet. u. Bact._, p. 478. Italics, in quotations, ours.
