Tinctoporellus epimiltinus, a causal fungus of butt rot of Japanese cypress
Forest Pathology 31 (1), 43-52
Abstract: One of the causal fungi of butt rot of Chamaecyparis obtusa in Kyushu Island, Japan, was identified as Tinctoporellus epimiltinus from cultural characters, and by mating and inoculation tests. The cultural characters of the isolates obtained from butt rot of C. obtusa and T. epimiltinus isolated from the basidiocarp tissue and from decayed wood were examined. The morphological characters and chemical reactions of the isolates from butt rot were typical for T. epimiltinus. Di-mon mating tests were performed between five monospore isolates of T. epimiltinus and five heterokaryotic isolates from the butt rot. All of the monospore isolates examined were heterokaryotized by the isolates from butt rot. Tinctoporellus epimiltinus isolates were inoculated on roots of 24-year-old C. obtusa. Butt rot was observed on all inoculated trees 1–2 years after the inoculation, and the inoculated fungus was re-isolated from the decayed parts of the inoculated trees.
