A practical approach to combining mitosporic and meiosporic fungi in one classification is described. The taxonomic data base used with the computer retrieval system Entrez for searching both GenBank and MEDLINE has been revised to conservatively place mitosporic fungi in the appropriate meiosporic taxon, thereby making the Deuteromycota redundant. As more data are available, it will be possible to move mitosporic taxa adjacent to their closest meiosporic relatives at the genus level. Placing mitosporic individuals in meiosporic species, however, is unlikely to be practical in most cases. Key words: Deuteromycota, fungi imperfecti, Entrez, fungal phylogeny, GenBank, fungal classification.
