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.
腐朽栓孔菌引起去皮栎木的明显的凹穴腐朽。聚合产物似乎在木质部降解之前就开始积累，形成对腐朽的阻隔。髓射线薄壁组织和早材导管不易降解，并残留在腐朽腔之间。化学分析表明，在初期腐朽过程中，从腐朽腔木材中去除了 97%的木质素、96%的木糖和 69%的甘露糖。尽管这些区域的纤维素有 53%被去除，但剩余的白色组织由相对纯净的纤维素组成。当释放的纤维素被进一步去除时，菌丝变得丰富。在腐朽的最先进阶段，菌丝从腔中消失，只留下稀疏的一层晶体，晶体中含有高浓度的钙。
