The distribution of Phellinus noxius is currently limited to tropical and subtropical regions of Southeast and East Asia, Oceania, Central America, and Africa. The ability of this pathogen to produce disease in temperate climates is unknown. We examined the pathogenicity of Phellinus noxius on four important conifer plantation species grown under temperate(More)

Phellinus noxius is a pathogenic fungus that causes brown root rot disease in a variety of tree species. This fungus is distributed in tropical and sub-tropical regions of Southeast and East Asia, Oceania, Australia, Central America and Africa. In Japan, it was first discovered on Ishigaki Island in Okinawa Prefecture in 1988; since then, it has been found(More)
The decay risk of airborne wood-decay fungi in the same volume of air was investigated by using an air sampler over the course of a year at three different sampling sites. Japanese cedar disks measuring 7.8 cm in diameter and about 3 mm in thickness, and with a moisture content of about 100 % were placed in a “BIOSAMP” air sampler and then exposed to 1000 l(More)
“Matsutake” mushrooms are formed by several species of Tricholoma sect. Caligata distributed across the northern hemisphere. A phylogenetic analysis of matsutake based on virtually neutral mutations in DNA sequences resolved robust relationships among Tricholoma anatolicum, Tricholoma bakamatsutake, Tricholoma magnivelare, Tricholoma matsutake, and(More)
The relationship between the taxa of airborne fungi and the decay risk was investigated. Airborne fungi in 1,000 l of air were trapped on Japanese cedar disks, and incubated in a damp container kept at 26ºC. After 16-week incubation, filamentous fungi grown on the disks were isolated and DNA extracted from each isolate was amplified with the primers(More)
