| Abstract: | Microscopic appearence of wood decomposed by Fomes annosus (Fr.) Cooke . Different stages of decay due to Fomes annosus were studied microscopically. The progress of disintegration is almost the same as that caused by other white rot fungi. Typical features are small zones of enzymatic activity, numerous borcholes of various sizes, and complete dissolution of parts of cellwalls. Pseudoparenchymatous accumulations of mycelium may block tracheids rather like partition walls, and skin-like formations and a great deal of amorphous, or crystalline inclusions may be formed in the lumina of the fibres. |
