The subject of this book is the classification of zoopathogenic fungi. The basic units in classification are the species, and these are arranged into hierarchal groups of genera, families, orders, classes, phyla, and kingdoms. The categories may be subdivided (e.g., subphylum, subclass, suborder) to indicate degrees of relationships. Populations within a given species that have some characteristics in common may be set apart as tribes or varieties or some other subset designation. The delineation of the zoopathogen Ajellomyces capsulatus, anamorph: Histoplasma capsulatum, goes as follows (1):Kingdom: Fungi Phylum: Ascomycota Class: Ascomycetes Order: Onygenales Family: Onygenaceae Genus: Ajellomyces Species: Ajellomyces capsulatus Variety: the varietal state applies to the anamorph (2): Histoplasma capsulatum var. capsulatum, H. capsulatum var. duboisii, and H. capsulatum var. farciminosumTable 1 The Kingdoms and Phyla of Microorganisms Covered in This BookKingdom: Fungi Phylum: Chytridiomycota Phylum: Zygomycota Phylum: Ascomycota Phylum: Basidiomycota Mitosporic FungiaKingdom: StraminipilaPhylum: Heterokonta Kingdom: Protoctista Phylum: Protista aThis group of anamorphic fungi-which lack any known teleomorphic stage-was atone time collected into a phylum Deuteromycota, but this term, still used for convenience in some arrangements (see, e.g., Chap. 8), has been largely discontinued. |
