Badhamia utricularis and Brefeldia maxima . 9 
in which could be seen grey lines of undigested spores showing 
the remains of the gills ; the hyphae had all disappeared. 
On October 26, I treated plasmodium in two glass boxes 
with sections of the pileus and gills of Agaricus fascicularis . 
The action was very different from what had been observed 
with the other agarics and with Boletus . In one box, after 
the slice had remained touching the plasmodium for 3J hours, 
no advance had been made ; so in order to stimulate its 
movement, I applied a small section of Boletus jlavus to the 
same wave and about an eighth of an inch from the 
A. fascicularis : in forty minutes not only was the Boletus 
absorbed, but the plasmodium had surged in a broad fan over 
the A. fascicularis which could be seen unchanged beneath it. 
On the following morning the plasmodium had retreated 
leaving the section with no apparent alteration surrounded 
by a mass of mucus, and here this experiment came to 
an end. 
In the other box with A. fascicularis, at 11.50 A. M. a 
section of pileus and ten gills was placed in contact with a 
strong wave of plasmodium; at 1.10 P. M. there was scarcely 
any advance upon it ; at 3.40 I made a note, ‘ fascicidar is 
rejected.’ Towards evening, however, the plasmodium ad- 
vanced and enveloped the section ; next morning it was left 
stranded and little changed. In the afternoon it was again 
swept over by the plasmodium, which began to prey upon 
the hyphae of the pileus, but it was evidently an unwholesome 
morsel, for it was surrounded with much grey mucus ; amongst 
this were many isolated patches of plasmodium pushing their 
way in the slime with constant change of form ; some appeared 
to have broken up into clusters of globules similar in size to 
the balls which escaped from the plasmodium in the experi- 
ment with A. rubescens\ a few of these coalesced and were 
taken in by the larger patches, but the greater number fell to 
pieces and died. Again the plasmodium withdrew, and 
although the section had been subjected to its action for 
22 hours, the gills had been so little affected that in the forks 
the spores could be seen arranged on their basidia in groups
