On the other hand, high temperature will kill them, but the spores may survive even the boiling temperature.

Mould fungus has been observed to develop rapidly at 130 deg.F.in a dry kiln in moist air, a condition under which an animal cannot live more than a few minutes.

This fungus was killed, however, at about 140 deg.

or 145 deg.F.[44] [Footnote 44: Experiments in kiln-drying _Eucalyptus_ in Berkeley, U.S.Forest Service.] The fungus (_Endothia parasitica_ And.) which causes the chestnut blight kills the trees by girdling them and has no direct effect upon the wood save possibly the four or five growth rings of the sapwood.[45] [Footnote 45: See Anderson, Paul J.: The morphology and life history of the chestnut blight fungus.Bul.No.7, Penna.
