AMANITA CITRINA, GON. AND RAB., A
FUNGUS NEW TO BRITAIN, IN EPPING
FOREST.
By GEORGE MASSEE, F.L.S. (Royal Herbarium, Kew).
This rare species was established and beautifully figured by
Gonnermann and Rabenhorst in the Mycologia Europaa, p. 2,
tab. 4 (1869), from German specimens. From that time up to
the present, the fungus has not been observed either in Germany
or elsewhere.

as the "Fly Agaric"—Amanita muscaria, L.—but the pileus
instead of being crimson is a clear deep lemon-yellow, with white
patches. The species is very poisonous.
I had occasion to visit the Forest during the week following
the last "Fungus Foray" (October 12th, 1901), for the purpose
of securing some specimens found immature during the Foray,
and was fortunate enough to discover two specimens of Amanita
