Scanning electron micrograph (SEM) of dry rot in a piece of domestic plywood (probably birch). This is a longitudinal section of the stem which shows the thickening on a large fractured vessel. Dry rot is a fungus (Serpula lachrymans) which infects damp timber. As the fungal network,or mycelium,grows,it destroys the cellulose in the wood & weakens its structure,thus causing fractures. The mycelium consists of thin strands known as hyphae,some of which are visible here. The micrograph shows the structure of the wood; the large cylindrical cells are xylem vessels,while the smaller ones are xylem parenchyma. Magnification: X 500 (at 10x8 inch size) | |
