artitions.
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]

[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
_Syrphidae_, which devour pollen, that fungus spores are
consumed.

[D] All attempts at Chiswick failed with some of the more esculent
species, and Mr. Ingram at Belvoir, and the late Mr. Henderson
at Milton, were unsuccessful with native and imported spawn.

[H] Mr. Berkeley has lately published a species under the name of _P.
Ellisii_, in which the gelatinous element is scarcely
discernible till the plant is moistened. There are two septa in
this species, and another species or form has lately been
received from Mr. Ellis which has much shorter pedicels, and
resembles more closely _Puccinia_, from which it is chiefly
distinguished by its revivescent character.
