From the Introduction:

The genus Alternaria was established in 1817 by Nees. According to M. B. Ellis (1971, 1976), it contains 44 species. A different number of species has been established by other taxonomists, mainly by combining several existing species into one or by dividing one species into several. Not being a taxonomic treatise, this book does not dispute the taxonomic position of Alternaria species and employs the epithets most commonly used in the literature.
