International Commission of Penicillium and Aspergillus

The three genera Aspergillus, Penicillium and Talaromyces are well-known and have been studied for centuries. These species have always attracted much attention because numerous species of these genera have important implications in applied research, including medical aspects, toxicology, spoilage and biotechnology. Taxonomies produced in the last century were based on phenotypical characters but new polyphasic approaches are carried out using molecular, biochemical in combination with various phenotypical characters have shown detailed species profiles which are in accordance with ecological characteristics.

The International Commission of Penicillium and Aspergillus coordinate taxonomic research and is established by the IUMS Mycology and Eukaryotic Microbiology – MEM Division.  The commission has discussed the recent changes in nomenclature and discussed the single name nomenclature in Penicillium and Aspergillus.

Nomenclatural papers dealing with the accepted species lists were published for Aspergillus (Samson et al. 2014), Penicillium (Visagie et al. 2014) and Talaromyces (Yilmaz et al. 2014).

This website provides the most current systematics and accepted list of species of Aspergillus, Penicillium, Talaromyces and related genera. Furthermore methods and recommendations how to identify species of these genera and links to the most current literature.
