Mucorales cause most human disease, accordingly, the term mucormycosis has commonly been used to describe diseases caused by these agents ignoring the role of entomophthorales in causing disease.
This grouping of the mucorales and entomophthorales as causes of zygomycosis, however, does not adequately reflect the distinct epidemiologic and pathogenic features of these two orders which have dramatically different disease manifestations [2].
Human disease caused by the order mucorales generally occurs in immunocompromised hosts as opportunistic infections and is characterized by a rapidly evolving course, tissue destruction and invasion of blood vessels [4, 5].

 Zygomycosis: An Emerging Fungal Infection   (Site not responding. Last check: 2007-10-09)
The Mucorales and Entomophthorales orders are vastly different with respect to the patient populations they affect.
Mucorales organisms often cause invasive disease, characterized by angioinvasion and tissue destruction, in immunosuppressed patients.
In infections caused by Mucorales fungi, the spores gain access to the host via the respiratory tract, whereas infections by members of the Entomophthorales usually result from skin abrasion.

 Mycology - Taxonomy - Zygomycota
Single spored sporangiola found in some Mucorales have been referred to as conidia, but as they form within a sporangial wall, the basal septum is not part of the wall of the spore and they are sporangiospores.
The members of the Mucorales are commonly referred to as sugar fungi, meaning that saprophytes respond rapidly to and grow rapidly on simple sugars in artificial media.
Some members of the Mucorales are commonly used to ferment foods and produce important industrial products such as lactic acid, amylases, rennin and organic acids.

Mucorales (Zygomycota) are ubiquitous, morphologically simple terrestrial fungi that are united taxonomically by possession of a coenocytic mycelium upon which nonmotile mitotic spores are produced asexually in uni-to-multispored sporangia, and zygospores, where known, are produced following fusion of sexually compatible hyphae.
Individual and combined data sets were analyzed by unequally weighted maximum parsimony (MP) to investigate evolutionary relationships among and within mucoralean families.
A major discovery of this study is that traditional family-level classification schemes for this order appear to be highly artificial as evidenced by polyphyly of four of the seven families containing two or more genera.

 decomposer
Many Mucorales are found acting as both primary and secondary saprotrophic sugar fungi.
Primary saprotrophic sugar fungi are those species which act as pioneer colonizers of sugary resources; this way of life is characterized by rapid growth, spoulation and spore germination which enable the fungus to avoid competition by arriving on such resources before potential competitors.
The ability of Mucorales to break down starch, fats and proteins,and their capacity for limited fermentative metabolism, is used in various oriental food fermentations.

Other families of the Mucorales often have fewer spores per sporangium, and their sporangia often have no columella.
Its tall sporangiophores have one large, terminal, columellate sporangium, but lower on the stalk there are branches which fork repeatedly in a dichotomous manner, the final branchlets ending in tiny mitosporangia (sporangioles) which contain only a few spores.

The pathogenic zygomycetes are largely in the order Mucorales, which is related to the term for this infection, mucormycosis.
Zygomycosis has also been used to refer to the disease caused by organisms of the class, but that term would include diseases due to fungi of the order Entomophthorales.
The latter diseases usually are different from those caused by Mucorales organisms (i.e., largely superficial infections) and are rare in North America.
