Baltisphaeridium bohemicum, (Eisenack, 1934 ex Eisenack, 1938), Downie and Sarjeant, 1965

Originally Hystrichosphaeridium bohemicum, subsequently (and now) Baltisphaeridium bohemicum; see also Ovum hispidum ssp. bohemicum (name not validly published). The name Ovum hispidum ssp. bohemicum was not validly published in Eisenack, 1934 since the specific name Ovum hispidum is not validly published. This combination was not validly published in Downie and Sarjeant, 1963 since these authors did not fully reference the basionym.
