2 Lister . — Notes on the Plasmodium of 
a sclerotium or resting stage. In this condition it may 
be stored away and can be brought back again into the 
active state by the application of water, at any time within 
several months. I shall have occasion to revert to this 
later. 
The notes I now offer refer principally to this species, 
which I have kept in constant streaming movement on various 
kinds of woody fungi for more than a year. 
In January, 1877, Badhamia was abundant in my garden 
at Leytonstone on some old hornbeam logs, which were 
also overgrown with extensive patches of Corticium puteanum , 
an effused fungus consisting of a central portion, brown and 
lurid from the multitude of its spores, surrounded with a 
white byssoid margin. The Badhamia advanced over the 
Corticium , entirely consuming the hyphae, or cut broad paths 
through the larger patches, leaving the bark to all appearance 
clean and bare where the plasmodium had passed on. 
I allowed the plasmodium which had been thus feeding, 
to crawl on a glass plate, w T hen its usual colour of rich 
chrome-yellow had changed to deep brown ; this alteration 
of colour was shown by the microscope to be caused by 
the countless undigested brown spores of the Corticium held 
in suspension. These spores could be seen hurried along 
in the torrents that coursed through the branching channels, 
rolling over and over among the minute yellow granules 
and transparent vacuoles of the plasmodium. 
When this had retreated from the glass plate, a map of 
its lace-like network was left behind, formed by the ejection 
on each side of the veins, of thousands of the Corticium- spores 
mixed with other refuse matter. 
I placed some wet cotton-wool in front of the still dingy 
plasmodium ; this it readily penetrated, and afterwards emerged 
possessing its normal yellow colour, leaving the wool charged 
with spores and other debris ; it soon after changed to 
sporangia which became black in the course of about thirty- 
six hours, and as they dried assumed the blue-grey colour 
characteristic of the species.
