| Abstract: | Two new Exobasidium species on Vaccinium spp. in Japan are described and discussed. Exobasidium kishianum, which causes Exobasidium leaf blight on V. hirtum var. pubescens and V. smallii, is characterized by its ellipsoid to ovoid basidiospores with (0–)1–3 septa. Its systemic infection is also observed. Exobasidium inconspicuum, causing Exobasidium leaf blister on V. hirtum var. pubescens, is characterized by its obovoid or ellipsoid to oval basidiospores with 0–4 septa. Mode of germination of the basidiospores
is by germ tube in both species.
