| Popis: | Xylobolus frustulatus caused a distinct pocket rot in decorticated oak. Polymerization products appeared to accumulate in advance of delignified wood to form barriers to decay. Medullary ray parenchyma and earlywood vessels were not readily degraded and remained between pockets of decay. Chemical analyses indicated that 97% lignin, 96% xylose, and 69% mannose were removed from pockets of wood during incipient decay. Although 53% of the cellulose was removed from these areas, the remaining white tissues were composed of relatively pure cellulose. Hyphae became abundant as the released cellulose was subsequently removed. In the most advanced stages of decay, hyphae were absent from pockets, and only a sparse lining of crystals, found to contain a high concentration of calcium, remained. |
