我们知道Peridermium pini(=Endocron-artium pini),P. harknessii(=E. harknessii)和P. filamentosum 是硬松类的一些同主寄主的干锈病菌。它们以锈孢子为手段,由松到松直接侵染。1972年Saho 和Takahashi 曾对由松到松的五针松干锈病做出有推论根据的报道。在北海道,在一种五针松——天然生长的偃松的嫩枝上采到了这种锈菌。于是,提出该菌为Peridermiu yamabense 新种(Saho,1981)。接种试验结果指出偃松、P. griffithii、美国五针松、日本五须松、P. peuce、P. str-obiformis 和美国白松都是这种锈菌的寄主。
We know that Peridermium pini (= Endocron-artium pini), P. harknessii (= E. harknessii) are some of the main rust-producing rusts of Pinus. They are rust spores as a means of direct invasion from pine to pine. In 1972, Saho and Takahashi made a corroborated evidence based on the loose pine rust of pine needles. In Hokkaido, this rust is found on a Pinus tabulaeformis, a naturally-grown Pinus sylvestris. Thus, it is proposed that the bacterium is a new species of Peridermiu yamabense (Saho, 1981). Inoculation test results indicate that Pinus thunbergii, P. griffithii, P. acutissima, P. japonicus, P. peuce, P. str-obiformis, and P. albopictus are host to this rust.
