To the Editor In the JAMA Dermatology Clinicopathological Challenge that describes a man with cutaneous mucormycosis, Xu and colleagues1 state that the pathogen, Mucor species, is a member of the “Zygomycetes class of the Mucorales order.”1(p80) This phrasing inverts the usual taxonomic hierarchy, and to make things more confusing, the Zygomycetes class no longer exists. Not that the “zygomycotic” organisms are extinct, but the taxonomic term Zygomycete is now obsolete. (The error of this phrase was recognized, and it was corrected online January 15, 2014; a printed correction was published in the March issue of JAMA Dermatology.2 We herein expand on that correction.)
