The Arthrodermataceae are a family of fungi from the order of the Onygenales . Many of their species live as dermatophytes on the skin of various mammals or humans.
features
As fruiting bodies, they form small, thin-walled, pedunculated Kleistothecia . They are covered with a loose peridium formed from hyphae , which has complex appendages. There is no tissue between the tubes . These are small, spherical or sack-shaped, thin-walled and quickly transient. The ascospores are unseptate and flattened at the poles, smooth and without a gelatinous shell. There is no stroma . Often only the secondary crop form is known. These are hyphomycetic and thallic . They form thick-walled conidia , which can sometimes be septate and ornamented.
Ecology and diffusion
Soil species of the Arthrodermataceae family live on substrates that contain keratin , such as soils or bird nests. Many species live on mammals including humans and are known as dermatophytes . They are therefore very widespread.
meaning
Many species grow on hair, skin and nails and, as dermatophytes, trigger various dermatophytoses such as ringworm .
Taxonomy
The Arthrodermataceae were first described by MV Locquin in 1972, but the description was invalid. In 1985, Randolph S. Currah validly described the family. There are 3 genera.
The following three genera are only known in their secondary crop form :
