McGraw-Hill Encyclopedia of Science & Technology, 10th edition. New York, NY: McGraw-Hill. p. 154-155. Interpretive Summary: Blastomycetes is a term used for yeasts that propagate asexually by splitting or budding. Although the term is increasingly obsolete (it is not used as a taxonomic group by contemporary taxonomists) it sometimes persists as an informal term of convenience and is frequently encountered in older literature. Two older systems of classification are noted: Cryptococcales (for ascomycetous yeasts) plus Sporobolomycetales (for basidiomycetous yeasts); and the alternative scheme of Saccharomycetes (for ascomycetous yeasts) plus Holobasidiomycetes and Teliomycetes (both of which are basidiomycetes, and include additional members other than those forming yeast states). In contemporary practice, yeasts producing asexually do not receive classification separate from other yeasts.
