Zygomycosis and the Joplin Tornado

Apophysomyces elegans

July 2011

This is Apophysomyces and you can see the cocktail glass appearance because of that pronounced apophysis. Apophysomyces also has rhizoids which are not shown on any of the illustrations I have here and they are produced in about the same place that you see with Lichtheimia. So once you see Apophysomyces you have to sort it out from Lichtheimia. Notice that the sporangiospores here are elongated, which is not what you see with most of the zygomycetes.
