In other _Discomycetes_ germination takes place in a similar manner. Boudier[P] narrates that in _Ascobolus_, when once the spore reaches a favourable place, if the circumstances are good, _i.e._, if the temperature is sufficiently high and the moisture sufficient, it will germinate. The time necessary for this purpose is variable, some hours sufficing for some species; those of _A. viridis_, for example, germinate in eight or ten hours, doubtless because, being terrestrial, it has in consequence less heat. The spore slightly augments in size, then opens, generally at one or other extremity, sometimes at two, or at any point on its surface, in order to pass the mycelium tubes. At first simple, without septa, and granular in the interior, above all at the extremity, these tubes, the rudiment of the mycelium, are not long in elongating, in branching, and later in having partitions. These filaments are always colourless, only the spore may be coloured, or not. Coemans has described them as giving rise to two kinds of conidia,[Q] the one having the form of _Torula_, when they give rise to continuous filaments, the other in the form of _Penicillium_, when they give birth to partitioned filaments. De Seynes could never obtain this result. Many times he had seen the _Penicillium glaucum_ invade his sowings, but he feels confident that it had nothing to do with the _Ascobolus_. M. Woronin[R] has detailed some observations on the sexual phenomena which he has observed in _Ascobolus_ and _Peziza_, and so far as the scolecite is concerned these have been confirmed by M. Boudier. 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.[S] [A] Seynes, J. de, "Essai d'une Flore Mycologique de la Montpellier," &c.

[C] The spores of Agarics which are devoured by flies, however, though returned in their dung in an apparently perfect state, are quite effete. It is, we believe, principally by the _Syrphidæ_, which devour pollen, that fungus spores are consumed.
