2010 - IRG/WP 10-10720
…size) to produce a de novo assembly of the genome of Antrodia radiculosa, a copper-tolerant brown rot fungus that is capable of aggressive wood decay. Quality analysis of the base calls in the dataset (8.95 Gb) showed that the majority of the nucleotide sequence was of the highest quality with 5% in the lowest…

Growth of the copper tolerant brown rot fungus Antrodia vaillantii on different substrates
1995 - IRG/WP 95-10121
In recent years the copper tolerant brown rot fungus Antrodia vaillantii caused severe damages on impregnated wood in ground contact. The pattern of decay gave the impression that impregnated wood was even more severely attacked than unimpregnated. To investigate this question more closely laboratory tests were…

…Isolates of Meruliporia incrassata and an isolate of Antrodia radiculosa caused the highest weight losses in CCA-treated southern yellow pine. One isolate of Meruliporia incrassata produced similar weight losses in CCA-treated and untreated southern pine after 10 weeks. Pine samples treated with very high…

…in outdoor exposed CLT was Gloeophyllum sepiarium, whereas Antrodia sp. was most common in CLT not exposed to outdoor conditions. The authors expect the variation in decaying agents found in CLT not externally exposed to increase as the buildings age. More research is needed regarding risk of fungal damage in massive…
