[Ecology, epidemiology and clinical symptomatology of Microsporum gypseum infections].

Microsporum gypseum is a geophilic fungus with a world-wide distribution, which is considered to be involved in keratin degradation in the soil. Since 1977, mycotic skin infections due to M. gypseum have been repeatedly observed in the Department of Dermatology in Graz, Austria. A predominance of females was evident. As a rare event, M. gypseum has also been cultivated from onychomycotic lesions.
