Dimargaris verticillata is a species of fungus within Kickxellomycota.

Discovery and taxonomy

D. verticillata was first described in 1959 from strains taken from mouse and frog dung in Claremont, California.[1] It is named for its verticillately arranged sporophores.[1]

Description

When grown on yeast-starch agar, colonies of D. verticillata have been described as white, becoming cream-colored with age.[1] Vegetative hyphae appear colorless, and are septate and branched, measuring roughly 2-4 μm in diameter. Haustoria begin simply, and become branched with growth.[1]

Sporophores are erect and colorless, and become "irregularly verticillately branched" with time. Sporophores produce as many as 18 branches which contain 2 cells each and are between 35-100 μm in length; these branches bear white, fertile heads.[1] Sporophores reach heights of roughly 1-3 mm; this can be used to differentiate D. verticillata from its close relative, Dimargaris cristalligena, which bears larger sporophores.[1]

Ecology and distribution

Since first discovered, D. verticillata has been known to parasitize the fungus Cokeromyces recurvatus.[1] Later studies have shown that many other fungi may be susceptible to D. verticillata parasitism, such as Mucor spp., Mortierella alpina, and Rhizopus stolonifer.[2]

In addition to California, D. verticillata has also been reported in Middlesex, England.[3]
