ABSTRACT

Fungi pertaining to Mucor are classied into one of the most variable groups, which is the subdivision Mucoromycotina. This replaced the widely known division Zygomycota, which is now considered obsolete for not constituting a monophyletic group and was recently substituted in accordance with Hibbett et al.1 The taxa that were located before in Zygomycota are included in the new divisions Glomeromycota (without clinical interest) and Entomophthoromycota and various other subdivisions of uncertain position such as Mucoromycotina, Kickxellomycotina, and Zoopagomycotina1 (Figure 24.1). In this sense, the subdivision Mucoromycotina includes the orders Mucorales, Endogonales, and Mortierellales. In Entomophthoromycota,2 several genera are found of clinical interest such as Basidiobolus and Conidiobolus, which are extremely deformative, limited to the tropics, and associated with chronic cutaneous or subcutaneous mycoses. Other genera located in Entomophthoromycota are, for example, Batkoa, Entomophthora, and Zoophthora, which have been isolated from insects and other soil invertebrates.
