Hysteriaceous fungi in the Russian Far East -: II.: The genus Hysterographium

The papers indicating Hysterographium species in Russia are more numerous in comparison with those listing Hysterium members, but, again, only three species, namely Hysterographium elongatum (Wahlenb.) Corda, H. fraxini (Pers. Fr.) De Not., and H. rehmianum Sacc., were reported (Potebnia, 1907; Naumov, 1915, 1964; Murashkinsky, Ziling, 1928; Lebedeva, 1933; Brezhnev, 1950; Oganova, 1954; Vlasov, Krangauz, 1956; Nasonova, 1958; Tomilin, 1966; Ryabova, Tomilin, 1978; Stepanova, Tomilin, 1986). The list of species known before our investigations in the Russian Far East is not longer, though it contributes some additional diversity. Apart from H. fraxini, H. biforme (Sacc.) Rehm and H. flexuosum (Schwein.) Sacc. were found here (Ablakatova, 1964, 1965; Koval, 1960, 1972; Bunkina, Nazarova, 1978). Later, H, mori (Schwein.) Rehm and H. subrugosum (Cooke et Ellis) Sacc., together with H. flexuosum and H. fraxini, were indicated for the northern Far East (Vasilyeva, 1987). This paper deals with almost the same set of species, and only H. fraxini is excluded. Hysterographium Cords, Icon. Fung., 5 : 34, 1842, emend. De Not., Giorn. Bot.
