Phylogeny of fungi. Most human pathogenic fungi are Ascomycota, with Candida species in Saccharomycotina, Pneumocystis in Taphrinomycotina, and the Onygenales clade of systemic pathogens and dermatophytes in Pezizomycotina. Basidiomycotina also harbors important pathogens, Cryptococcus and Trichosporon species in Agaricomycotina and Malassezia species in Ustilaginomycotina.
