252 THE HYMENOMYCETAL FUNGI OF EPPING FOREST,
as we are aware, has not yet been recognized anywhere else in
Europe. It is a very peculiar species, and could hardly fail to be
seen, being as white as ivory, with a cap something like a silver
thimble.
The subgenus Mycena is made up of small species, and in these
the Forest is rather strong. Two species, entirely new, have been
found, Ag. pullatus and Ag. leucogalus, and though first described
from near Chingford, have since been found elsewhere. The last,
when broken across the stem, exudes a white milky juice.
Omphalia is a subgenus which includes 37 species that are
British, and only seven are found here, but they are very small
and inconspicuous, so that it is probable others have been over-
looked.
The last of the white-spored subgenera is Pleurotus, of which six
that are found in Epping Forest must be considered as rare. No
new species has occurred, while five of the 14 species are somewhat
common.
There are nearly as many white-spored species of true Agarics
known in Britain as of all the other coloured spored species put
together. This is intended as a hint that the present analysis is not
meant to be interminable, and give you courage to hope that so
much of dry detail must soon come to an end.
The pink-spored section contains little worthy of note in respect
of our locality. The only Volvaria yet met with, Ag. (Volvaria)
medius, is rare, and we know of no other British locality. Ag.
(Clitopilus) carneo-albus is a fungus described by Withering, and the
Monk's Wood specimens are probably the only ones which have been
seen since his time. The larger fungus known on the Continent
under this name hardly appears to be the same species ; therefore the
Epping Forest fungus possesses considerable interest, as it agrees so
well with the description by Withering that no room is left for doubt.
Having been figured in the "Illustrations," it is to be hoped that
now it will be recognized as the typical form. It may seem strange
that no species of the subgenus Leptonia has occurred in our area,
but that may be accounted for by the fact that they are lovers of
lawns and damp pastures.
We come now to the section with rust-coloured spores, and of
these the subgenus Pholiota is represented by only rather common
species. Inocybe again has but few species, and with the exception
of A. destrictus and A. eutheles, includes only common species. A
