Categories of significance identified in the 1090 sequenced fungal species. Pathogens comprise the largest category within which plant pathogens are predominant. “Medically important” species represent fungi that are not directly pathogenic, but cause food or environmental contamination. “Interesting” species are studied for their development or metabolism. “Niche-specific” refers to species occupying abiotic niches, whereas “symbiotic” species are associated with other organisms. “Economically important” species have a use in the economy, (e.g. culinary, biocontrol or pharmaceutical industries). Most of the parasites belong to Microsporidia.
