This report deals with rust diseases of birches and fir caused by Blastospora betulae KANEKO et HIRATSUKA, f. and Pucciniastrum boehmeriae P.et H.SYDOW, respectively. 1) Birch rust : field surveys and examinations of herbarium specimens revealed that B.betulae is parasitic on the leaves of such birches as Betula globispica SHIRAI, B.platyphylla SUKATCHEV var.japonica HARA, and B.ermanii CHAM. as well as on B.grossa SIEB. et ZUCC. on which the fungus originally was described. The fungus is distributed in the montane and subalpine zones in central and northern Honshu of Japan. It is suggested that the rust fungus is a heteroecious species from the negative result of basidiospore inoculations onto birches and observations of the disease in the field. 2) Fir rust : inoculation experiments proved that the aecial state of P.boehmeriae causes a needle rust on Abies firma SIEB. et ZUCC. A description is given for the first time of the aecial state.
