atisfactorily for the
mystery, but, at the same time, feel equally unwilling to invent
hypotheses in order to conceal our own ignorance.

will be exceptions.

spores attached end to end.

CULTIVATION.

The cultivation of fungi in this country for esculent purposes is
confined to a single species, and yet there is no reason why, by a
series of well-conducted experiments, means should not be devised for
the cultivation of others, for instance, _Marasmius orcades_, and the
morel. Efforts have been made on the Continent for the cultivation of
truffles, b
