MYCETOZOA FOUND DURING THE FUNGUS
FORAY ON OCTOBER 15th, AND THE
CRYPTOGAMIC FORAY ON NOVEMBER 12th, 1938,
IN EPPING FOREST.
By G. LISTER, F.L.S.
THE route taken by the party on October 15th was from
Theydon Bois, through the Forest to the "Wake
Arms" and on to High Beach. After a dry summer and early
autumn, the recent rains had not soaked the leaf beds under the
hollies and hornbeams enough to make them such favourable
feeding grounds for plasmodia as in some previous years, and the
mycetozoa found on leaves were far fewer than those on old logs,
stumps and sticks. Altogether twenty-four species were
obtained.
