Partridge Wood: A Novelty Wood

The rot caused by Stereum frustulosum (Pers.) Fr. in oak produces a condition called “Partridge wood.” The wood takes on a dark brown color, then disintegrates, leaving spindle-shaped pockets or holes that are lined with white mycelium. In an attempt to establish the effect of the rot on the strength properties of the wood, samples were collected and tested for strength and stiffness. It is apparent that the decay organism affects all properties of the wood, but not so seriously as to make partridge wood totally unusable. Although it would not be suitable for load-bearing beams or columns, it could be used for wall paneling, picture frames, and other products where strength is of less importance than appearance. Finishing of partridge wood with clear lacquer poses problems as the pockets of decay absorb the lacquer, making it difficult to obtain a coating of satisfactory depth. Also, the contrast in color between the white pockets and brown wood is lost when the wood is lacquered. It would probably be best not to finish the wood for most uses, since partridge wood might best be used to achieve a rustic appearance rather than the look of sophistication and elegance. Wiping stains, however, may be used on some products with good effect.
