| Abstract: | Two species of Ophiostoma were isolated from four bark beetles (i.e., Cryphalus montatus, C. piceae, Dryocoetes hectographus, and Polygraphus proximus) infesting Abies veitchii and from their galleries in the wave-regenerated forests in the central part of the main island (Honshu) of Japan. One of
them is described here as a new species, Ophiostoma subalpinum, and the other is identified as O. davidsonii, newly reported in Japan. Ophiostoma subalpinum is characterized by short ostiolar hyphae, oblong or allantoid ascospores enclosed in a thin, hyaline sheath, and a Pesotum anamorph.
