Abstract: A fungus, isolated from blue stain timbers of Hevea brasiliensis and Pinus massoniana, was identified as Botryodiplodia theobromae Pat.. The fungus was also found to be capable of infecting the wood samples of Eucalyptus citriodora, Acer mono and Calamus cgregius.The results of the tests on its temperature tolerance showed that the fungus survives within the stained Rubberwood subjected to a temperature of 75℃ for 24 hours and within the stained wood samples of Pinus massoniana subjected to a temperature of 60℃ for 96 hours. The hyphae of this fungus were observed to occupy the rays primarily and to follow the rays into the wood mainly through pits. They mainly distributed within the vessels of the stained Rubberwood and the resin canals and rays of the stained wood of Pinus massoniana.
