WHAT TO DO ABOUT ASPERGILLUS? NEWS An issue which unavoidably arose with molecular studies including the whole consideration for adoption, along with the move from dual nomenclature genomes of several species. An analysis ones in Penicillium and Talaromyces (which for pleomorphic ascomycetes and based on 25 loci by Houbraken et al. have not occasioned controversy). The lists basidiomycetes to one name for one (2014) showed that Aspergillus was are available on the ICPA website (www. species, was what to do about Aspergillus.
