7 belong to _Polyporus_. Leveille added 87
species, making a total of 246 species. The fungi of Sumatra, Borneo,
and other islands are partly the same and partly allied, but of a
similar tropical character.

The fungi of the island of Ceylon, collected by Gardner, Thwaites, and
Koenig, were numerous. The Agarics comprise 302 species, closely
resembling those of our own country.[l] It is singular that every one
of the subgenera of Fries is represented, though the number of species
in one or two is greatly predominant. _Lepiota_ and _Psalliota_ alone
comprise one-third of the species, while _Pholiota_ offers only a
single obscure species. The enumeration recently published of the
succeeding families contains many species of interest.

In Africa, the best explored country is Algeria, although unfortunately
the flora was never completed.[m] The correspondence between the
fungi of Algeria and European countries is very striking, and the
impression is not removed by the presence of a few sub-tropical forms.
It is probable that were the fungi of Spain known the resemblance would
be more complete.

From the Cape of Good Hope and Natal collections have been made by
Zeyher,[n] Drege, and others, and from these we are enabled to form a
tolerable estimate of the mycologic flora. Of the _Hymenomycetes_, the
greater part belong to _Agaricus_: there are but four or five
_Polypori_ in Zeyher's collection, one of which is protean. The
_Gasteromycetes_ are interesting, belonging to many genera, and
presenting two, _Scoleciocarpus_ and _Phellorinia_, which were founded
upon specimens in this collection. _Batarrea_, _Tulostoma_, and
_Mycenastrum_ are represented by European species. There are also two
species of _Lycoperdon_, and one of _Podaxon_. Besides these, there is
the curious _Secotium Gueinzii_. The genus _Geaster_ does not appear
in the collection, nor _Scleroderma_. Altogether the Cape flora is a
peculiar one, and can scarcely be compared with any other.

At the most, only scattered and isolated specimens have been recorded
from Senegal, from Egypt, or from other parts of Africa, so that, with
the above exceptions, the continent may be regarded as unknown.

From this imperfect summary it will be seen that no general scheme of
geographical distribution of fungi can as yet be attempted, and the
most we can hope to do is to compare collection with collection, and
what we know of one country with what we know of another, and not
