I, INTRODUCTION. 
An investigation of the mould fungi which contaminate 
chilled and frozen meat was commenced in 1918 when con- 
siderable quantities of imported meat were found to be damaged 
in this manner, probably chiefly on account of the abnormally 
long periods of storage which war conditions necessitated. Since 
then, numerous specimens of mould growths upon cold-store 
meat have been examined, and investigations have been made 
concerning the conditions under which these moulds develop. 
In 1921 a report (3) upon the ‘“‘ Black Spot”’ of chilled and frozen 
meat was published (Special Report No. 6, Food Investigation 
Board), and the present account contains a description of the 
other moulds which have been encountered during the course 
of the work*. These researches have been carried out under the 
auspices of the Food Investigation Board of the Department of 
Scientific and Industrial Research. 
With one exception, all the fungi described have been re- 
peatedly observed during the last three years upon cold-store 
meat, and in view of the multiplicity of fungoid forms, it is 
somewhat remarkable that those which occur upon meat are 
so few in variety. Our observations agree well with those of 
Massee(12), but he described in detail only Cladosporium her- 
barum, the cause of ‘Black Spot.’’ Some of the other forms he 
mentioned, e.g. Penicillium glaucum, Mucor mucedo and Mucor 
vacemosus we have seen, but Oospora carneola, Verticillium 
lateritium, Penicillium candidum and Phycomyces nitens we have 
not seen, notwithstanding repeated search. Klein(:0) referred
