Abstract
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.
