Other mstances and some partial exceptions in the simplest of the Chytridieae will be described in different places in Chapter V. The modes of formation of sporangia in germination have been already considered in the foregoing sections; here, therefore, we have only the other. Fig. ss. Puccinia graminis.

The characteristic feature in tube-germination is that the spore grows out at one or more than one spot in its surface into a tubular process which is of the nature of a fungal hypha. This the first product of germination is accordingly known as tht germ-tube (Keimschlauch). If the tube receives sufficient nourishment it developes directly in many cases into a myceliiun or thallus like that of the parent, and it is there- fore \htprimordium of the mycelium (Fig. 55 D).
