The orders arranged after the method followed in the universities and schools of Great Britain, its colonies, America, and India; with additions, an appendix on the natural method, and a synopsis of the orders, by J.D. Hooker. Botany. 952 XIII. FUNGI. were they to be considered as stylospores or reproductive organs. Zygospores are round or oval cells, terminating a filamentous receptacle, or developed on the sides of two branchlets from one branch, which approach and unite so as to form a single body (zygosporangium) containing a single spore (siygospore). This mode of fertilization has hitherto only been observed on Syzygites megalocarpus, Ascophora rhizopus, and Mucor fusipes. Secondaet bepeoductive organs.—The conidia are simple cells, globose or ovoid, naked, pulverulent, isolated, or agglomerated in a compact mass. In the first case they are joined end to end, or arranged in racemes, or situated at the extremity of simple or branched filaments; in the second case, they resemble variously coloured pulpy or fleshy tubercles, which soften, and are almost entirely dissolved in water. The stylospores are ovoid, spheroidal or elliptic cells, straight or curved, simple or chambered, variously coloured, always pedicelled and included in a conceptacle {pycnide). The zoospores are absolutely identical with those of some Algw (see p. 976); they are furnished with two hairs, by the help of which they move readily; if placed on a slightly moistened leaf they germinate by enjitting filaments which penetrate the stomata, or pierce the epidermis, and ramify in the parenchyma; they have been observed in the joints of Cystopus and in Peronospora, Whatever view may
