- A genus of pathogenic fungi causing dermatophytosis. In appropriate culture media, characteristic macroconidia are seen; microconidia are rare in most species. [micro- + G. sporos, seed]- M. audouinii an anthrophilic fungal species of fungi that has caused epidemic tinea capitis in children.- M. canis the principal cause of ringworm in dogs and cats and a zoophilic fungal species of fungi causing sporadic dermatophytosis in humans, especially tinea capitis in children with cats and dogs.- M. canis, var. distortum a zoophilic fungal species that causes dermatophytosis in humans and animals; seen among laboratory animal handlers.- M. ferrugineum an anthropophilic fungal species that causes dermatophytosis, primarily in Japan and the Far East.- M. fulvum a geophilic fungal species that causes dermatophytosis in humans and is a member of the M. gypseum complex whose ascomycetous state elevates it to the rank of a specific species.- M. gallinae a fungal species that causes dermatophytosis in fowl and, occasionally, in humans; due to its broadly clavate macroconidia, it was erroneously classified as a species of Trichophyton.- M. gypseum a cause of ringworm in dogs and horses and occasionally other animal species; a geophilic complex of fungal species causing sporadic dermatophytosis in humans.- M. nanum a geophilic fungal species that is the principal cause of ringworm in pigs; rarely causes dermatophytosis in humans.- M. persicolor a geophilic fungal species that causes dermatophytosis in voles, field voles, and, occasionally, humans; its ascomycetous state is Nannizzia persicolor.- M. vanbreuseghemi a zoophilic fungal species that causes dermatophytosis in dogs and squirrels, and occasionally in humans.

* * *Mi·cros·po·rum (mi-krosґpə-rəm) [micro + Gr. sporos seed] a genus of Fungi Imperfecti, family Moniliaceae, mostly small-spored ectothrix ringworm fungi (dermatophytes); numerous species are causes of diseases of the skin and hair. As the perfect (sexual) stages are identified, they are classified in the genus Arthroderma. Called also Microsporon.
