They grow more quickly in the vessels, but are not ultimately assembled into strands in these parts. The wood is eventually separated into plates or cuboidal areas, and the texture of the wood becomes light and corky. The separation of the wood into plates is accomplished by the growth of white strands or bands of the mycelium in all three direc- tions, that is, radially, tangentially, and longitudinally. The wood elements, which gradually disappear under the solvent action of. Fig. 224. Polyporvs squamosus, Upper Surface the fungus, are largely those which are less lignified, such as the fibers between the vessels, that is, those usually produced only dur- ing spring growth. In the dissolution of the cells, first the contents, next the secondary cellulose layer, and finally the middle lamellae disappear, so that during the process the cells do not become sepa- rated in the early stages of decay. The mycelium unquestionably possesses a variety of enzymes. According to Buller, " from an enzymotic study of wood undergoing decay from the agency of Polyporus squamosus evidence was taken that various enzymes are excreted by the fungus mycelium. Thus.
