his doctorate at the University of Strasburg, 1873.

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.

THE MYXOMYCETES (_Link_) _DeBary_

Chlorophyl-less organisms whose vegetative phase consists of a naked
mass of multinuclear protoplasm, the _plasmodium_; reproduced by spores
which are either free or more commonly enclosed in sporangia, and which
on germinating produce ciliated or amoeboid zoospores, whose
coalescence gives rise to the plasmodium.

The Myxomycetes are,--

_A._ _Parasites_, in the cells of living plants PHYTOMYXINAE

_B._ _Saprophytes_, developed in connection with decaying
vegetable matter:

_a._ With free spores EXOSPOREAE

_b._ With spores in receptacles or sporangia MYXOGASTRES

Sub-Class PHYTOMYXINAE _Schroeter_
