Abies Mariesii and Abies Veitchii distributed in the primeval forests of the high mountainal regions of Honshu, Japan were found to be affected by the two types of butt-rot, namely brown rot and white pocket-rot which have never been reported from Honshu.In the decayed woods of Abies Mariesii and A.Veitchii attacked by the brown butt-rot fungus, there are numerous brown chlamydospores which are never found in the case of Phaeolus Schweinitzii.The isolations of the fungi were made from the decays of Abies Mariesii and three isolates were obtained. According to the data published by C. W. FRITZ, M. K. NOBLES and S. KAMEI, the three isolates were completely identified as Tyromyces balsameus (PECK) MURR. Another white butt-rot fungus of Abies Mariesii and A. Veitchii was found to be prevalent in the damp situations of primeval forests of Oze districts and Mt. Yatsugatake.The fruiting bodies were produced on the butts of the affected trees and were deternmined as Fomitopsis annosa (FR.) KARSTEN.Cultural studies were done and it was found that the mycelia of this fungus had conidiophores of Oedocephalum.Fomitopsis insularis (MURR.) IMAZEKI, which is very similar to Fomitopsis annosa, also has wide distributions in Japan, but it is found usually on dead logs or stumps of conifers and does not attack the living trees.
