many forms, which has come
to be called a fungoid odour; it is the faint smell of a long-closed
damp cellar, an odour of mouldiness and decay, which often arises from
a process of eremocausis. But there are other, stronger, and equally
distinct odours, which, when once inhaled, are never to be forgotten.
Amongst these is the fetid odour of the common stinkhorn, which is
intensified in the more beautiful and curious _Clathrus_. It is very
probable that, after all, the odour of the _Phallus_ would not be so
unpleasant if it were not so strong. It is not difficult to imagine,
when one encounters a slight sniff borne on a passing breeze, that
there is the element of something not by any means unpleasant about
the odour when so diluted; yet it must be confessed that when carried
in a vasculum, in a close carriage, or railway car, or exposed in a
close room, there is no scruple about pronouncing the odour intensely
fetid. The experience of more than one artist, who has attempted the
delineation of _Clathrus_ from the life, is to the effect that the
odour is unbearable even by an enthusiastic artist determined on
making a sketch.

Perhaps one of the most fetid of fungi is _Thelephora palmata_. Some
specimens were on one occasion taken by Mr. Berkeley into his bedroom
at Aboyne, when, after an hour or two, he was horrified at finding the
scent far worse than that of any dissecting room. He was anxious to
save the specimens, but the scent was so powerful that it was quite
intolerable till he had wrapped them in twelve thick folds of the
strongest brown paper. The scent of _Thelephora fastidiosa_ is bad
enough, but, like that of _Coprinus picaceus_, it is probably derived
from the imbibition of the ordure on which it is developed. There
needs no stronger evidence that the scent must not only be powerful,
but unpleasant, when an artist is compelled, before a rough sketch is
more than half finished, to throw it away, and seek relief in the open
air. A great number of edible Agarics have the peculiar odour of
fresh meal, but two species, _Agaricus odorus_ and _Agaricus
fragrans_, have a pleasant anise-like odour. In two or three species
of tough _Hydnum_, there is a strong persistent odour somewhat like
melilot or woodruffe, which does not pass away after the specimen has
been dried for years. In some species of _Marasmius_, there is a
decidedly strong odour of garlic, and in one species of _Hygrophorus_,
such a resemblance to tha
