Nomenclature The scientific classification for this particular class is particularly tricky, with one particular species having both the anamorph (asexual form), and teleomorph (sexual form) names used in reference to them. e.g. anamorph form = Penicillium; teleomorph form = Talaromyces or Eupenicillium. Morphology Many members (Eurotiales, Onygenales) produce an enclosed structure cleistothecium within which they produce their spores.
