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 amœboid zoöspores, whose coalescence gives rise to the plasmodium.
The Myxomycetes are,—
| A. Parasites, in the cells of living plants | Phytomyxinæ | |
| B. Saprophytes, developed in connection with decaying vegetable matter: | ||
| a. With free spores | Exosporeæ | |
| b. With spores in receptacles or sporangia | Myxogastres | |
Sub-Class PHYTOMYXINÆ Schroeter
- 1889. Phytomyxinae Schroeter, Engl. u. Prantl., I., i., pp. 1 and 5.
The parasitic Myxomycetes affecting plants include but few (four or five) species, distributed among four genera. All are parasites in the cells of particular hosts; their vegetative phase is plasmodial and their spores are formed by the simultaneous breaking up of the plasmodium into an indefinite number of independent cells. But a single genus need here concern us,—
