''Trichophyton rubrum'' is a dermatophytic fungus in the phylum Ascomycota, class Euascomycetes. It is an exclusively clonal,〔 anthropophilic saprotroph that colonizes the upper layers of dead skin, and is the most common cause of athlete's foot, fungal infection of nail, jock itch, and ringworm worldwide.〔 ''Trichophyton rubrum'' was first described by Malmsten in 1845 and is currently considered to be a complex of species that comprises multiple, geographically patterned morphotypes, several of which have been formally described as distinct taxa, including ''T. raubitschekii'', ''T. gourvilii'', ''T. megninii'' and ''T. soudanense''.〔〔〔 ==Growth and morphology== Typical isolates of ''T. rubrum'' are white and cottony on the surface. The colony underside is usually red, although some isolates appear more yellowish and others more brownish.〔 ''Trichophyton rubrum'' grows slowly in culture with sparse production of teardrop or peg-shaped microconidia laterally on fertile hyphae. Macroconidia, when present, are smooth-walled and narrowly club-shaped, although most isolates lack macroconidia.〔 Growth is inhibited in the presence of certain sulfur-, nitrogen- and phosphorus-containing compounds. Isolates of ''T. rubrum'' are known to produce penicillin ''in vitro'' and ''in vivo''.〔
