Fig. 9.— Mucor fusiger; A, young sexual organs; B,after fertilization. Highly magnitied. the Phycophytes, is fertilized by spermatozoidsfrom an antherid which, again, does not differin any essential respect from that of the Phy-cophytes. However, the result of the fertiliza-tion is the formation of a more or less com-pound body which the botanist recognizes as aprimitive kind of fruit. Hence, the aquaticCarpophytes are sometimes known as FruitTangles. In these fruits are spores, and theseon escaping and germinating give rise to newplants. poisoxors FUXGi — :/: :.• li X ^- -r ~ ts ^ — « If f i = S g ? « 3 = c 5.1-5 f C C P H

FUNGI The chlorophyll-bearing Carpophytes com-prise nearly 2,500 species, and are widely dis-tributed in the salt and fresh waters of theglobe. From these have sprung an enormoushost of parasitic and saprophytic species, whichare colorless, and constitute the great bulk of thefungi of the world, aggregating fully 100 timesas many species as those from which theysprang. In changing from the holophytic structureand habits of their ancestral types, these hys-terophytes (fungi) have suffered much degenera-tion of the vegetative plant-body, while the re-productive apparatus has been relatively enlargedand multiplied. This is in accordance with thewell-known law that since hysterophytes do notmake carbohydrates they have little need oflarge vegetative bodies, and further, that sincethey are dependent upon particular hosts ororganic matter for their food, they inust providemore lavishly for propagation. Many of thesefungi are little more than absorbing and repro-ducing organisms, the vegetat
