There is no reason for doubt that in other of the Discomycetes the germination of the sporidia is very similar to that already seen and described, whilst in the pyrenomycetes, as far as we are aware, although the production of germinating tubes is by no means difficult, development has not been traced beyond this stage.

The Uredines are not less rich, he adds, in reproductive bodies of divers sorts than the pyrenomycetes and the Discomycetes; and we should not be surprised at this, since it seems to be a law, almost constant in the general harmony of nature, that the smaller the organized beings are, the more their races are prolific.
