Abstract:

The sequence of changes observed microscopically that occurred in wood throughout successive stages of decay was studied in the sapwood of a hardwood, sweetgum Liquidambar styraciflua L., and of a softwood, southern pine Pinus sp.. The fungi used were Polyporus versicolor L. ex Fr., a white-rot fungus, and Poria monticola Murr., a brown-rot fungus. Light microscopy, plus the techniques of polarization and ultraviolet-absorption microscopy, was used to make the observations on sections 4 microns thick cut from celloidin-embedded specimens.
