Baltisphaeridium trifurcatum ssp. procerum, (Sannemann, 1955), Downie and Sarjeant, 1965

Now Multiplicisphaeridium procerum (an acritarch species). Originally Hystrichosphaeridium trifurcatum ssp. procerum, subsequently Baltisphaeridium trifurcatum ssp. procerum, thirdly (and now) Multiplicisphaeridium procerum (an acritarch species). This combination was not validly published in Downie and Sarjeant, 1963 since these authors did not fully reference the basionym.
