Mucoraceae Overview The concept of Mucoraceae has undergone a number of changes in the last few years from the one presented as part of a comprehensive survey of Mucorales by Hesseltine and Ellis inwhich refected the thinking of most students of the Mucorales up to that time and on to the end of that decade Benjamin, As treated by Hesseltine and Ellis Mucoraceae included some 19 to 21 genera of Mucorales having only more or less large, multispored, columellate sporangia, although in a few genera e.

Subsequent to the review by Hesseltine and Ellis several genera were added to the Mucoraceae; these were described as new [Halteromyces Shipton and Schipper, ; Thermomucor Subrahamanyam et al. Several realignments of genera restricted the limits of Mucoraceae by removing a number of genera to other families.

Mirza Mirza et al. Finally, von Arx further limited the circumscription of Mucoraceae by establishing the Absidiaceae for those genera formerly included in the family which have a more or less apophysate sporangium; von Arx also created the Phycomycetaceae for Phycomyces and Spinellus.

Zygomycetes: Mucoraceae

Umbelopsis is now included in the Umbelopsidaceae. Thamnidiaceae is considered a synonym of Mucoraceae because the type for the latter family, Thamnidium elegans Link, is now a member of the Mucoraceae as presently circumscribed.

A data set consisting of six taxa from the Mortierellales and 75 spp. Mucoraceae contains five genera here based on the above phylogenetic analyses Helicostylum, Mucor s. The other genera that constituted the Thamnidiaceae sensu Benny Benny, ; Benny and Benjamin,included Backusella Hesselt.

Classification Mucoraceae Dumortier Com. Mycelium well developed; rhizoids and stolons lacking. Sporangiophores erect or ascending, simple or branched, arising from substrate mycelium or aerial hyphae.

Sporangia similar, more or less globose, columellate, multispored, without an apophysis; wall diffluent, deliquescent, or persistent. Sporangiola, if formed, similar, more or less globose and nonapophysate or obpirform and apophysate, columellate, wall persistent. Suspensors formed on aerial hyphae or sporangiophores or aerial hyphae, opposed orapposed, more or less equal, often swollen, with or without appendages, may be wrapped around one another.

Zygospores with a pigmented, usually dark, thick-walled zygosporangium that is ornamented with warts or spines,it can be more or less translucent and undulate to smooth; smooth-walled, translucent zygosporangia enclosing a pigmented zygospore can also be formed; suspensors opposed or apposed, more or less equal, unadorned.

Sporangia and sporangiola produced —— B. Sporangia produced —— D B. Sporangiola obpiriform, or 4 produced on a relatively long, twisted and contorted lateral branch arising from the sporangiophore —— Pirella BB.

Sporangiola more or less globose, many produced on fertile branches that are straight, curved or dichotomously branched —— C C.

Fertile branches terminate in sterile spines, arise pseudovertilcellately from the main sporangiophore or its branches —— Helicostylum CC.

Fertile branches do not terminate in sterile spines, arise verticellately from the main sporangiophore or its branches, remainder of branching dichotomous —— Thamnidium D. Sporangiophores simple or sympodially branched; sporangia more or less globose, off-white to grayish in color; sporangiolar wall deiquescent —— Mucor s.
