N2 - Fungal systematics is an essential part of biological research especially in the context of its
ecological and economic implications. The classification of pleomorphic and non-pleomorphic
anamorphs, however, is unsettled, which can be attributed to the historical practice of the dual
nomenclature/classification system. This paper reviews the historical establishment and
limitations of the dual system of classification, and narrates the possible utilities of DNA
sequence-data in developing a system of classification based on evolutionary relationships. The
dual classification system is a failed hypothesis. DNA sequence-data are now routinely used to
link anamorphs with a holomorph and to provide phylogenetic placement for anamorphs with
unknown teleomorphs. Emerging phylogenetic and nomenclatural scenarios in the
Botryosphaeriales, Chaetosphaeriales, Fusarium graminearum, pestalotiopsis-like anamorphs,
and the Mycosphaerella complex are illustrated to indicate potential nomenclatural and
taxonomic complexities associated with the dual nomenclature/classification system. The
mycological community has a daunting task of developing a system of classification that fulfils
the needs of diverse taxonomic users. Molecular characters and tools are, undoubtedly, an
indispensable part of fungal systematics.
