Microsporum mirabile and its teleomorph Arthroderma mirabile, a new dermatophyte species in the M. cookei clade

A novel dermatophyte species is described in the Microsporum cookei clade. It differs significantly from known taxa in the two molecular markers analyzed, i.e., ITS and partial beta-tubulin (BT2). Morphologically the species was characterized by smooth-or only slightly rough-walled conidia, but isolates rapidly became pleomorphic with sparse, smooth-and thick-walled macroconidia in addition to microconidia. A teleomorph was found after mating.
