From a series of intra- and interspecific crosses as well as protoplast fusions, we concluded that a revision of the genus is required. Being interfertile, S. pombe and S. malidevorans have to be included in one species S. pombe. From the protoplast fusion results, this new taxon seems to be closely related to S. octosporus. The results obtained are discussed in connection with the characteristics of the low temperature spectra of the cytochromes. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-128-9-1989
