在实验室中，白杨木块被松皮、髓质Poria - medulla-panis和木球选择性地去木素化。8周后，只有木块的外表面被选择性地去木质化。在4周、8周和12周后获得的体重减轻百分比表明，龋齿以相对恒定的速度发生。选择性去木质素化的木材，只有当木质素从细胞壁上被广泛去除时，才能用扫描电镜进行鉴定。12周后，在整个木块中都能形成去木质素的木袋。
Aspen wood blocks were selectively delignified in the laboratory by Ischnoderma resinosum, Poria medulla-panis, and Xylobolus frustulatus. After 8 weeks only the outer surfaces of wood blocks were selectively delignified. The percentages of weight loss obtained after 4, 8, and 12 weeks showed that decay occurred at a relatively constant rate. Selectively delignified wood could be identified by using scanning electron microscopy only when lignin had been extensively removed from cell walls. X. frustulatus was able to form pockets of delignified wood throughout blocks after 12 weeks.
