Abstract
Isolates previously identified as Microsporum gypseum (Bodin) Guiart & Grigorakis have been found to be the imperfect states of Nannizzia incurvata Stockdale, N. gypsea (Nannizzi) comb. nov. and N. fulva sp. nov. The three species are heterothallic and cross-mating does not occur between them. They show slight but constant differences in their colonial and microscopic appearance on agar media and in the form of the peridial hyphae and appendages of their cleistothecia. Although the Microsporum states of N. incurvata and N. gypsea can be distinguished from each other it has been impossible to decide which, if either, of these is M. gypseum, sensu stricto. The imperfect state of N. fulva is M. fulvum Uriburu which had previously been considered synonymous with M. gypseum. Pilzstämme, die als Microsporum gypseum (Bodin) Guiart & Grigorakis bestimmt wurden, sind nun als imperfekte Stadien von Nannizzia incurvata Stockdale, N. gypsea (Nannizzi) comb. nov., und N. fulva sp. nov. erkannt worden. Obwohl die Microsporum-Stadien von N. incurvata und N. gypsea voneinander unterschieden werden können, ist es vorläufig noch unmöglich, zu entscheiden, welche dieser beiden Arten (wenn überhaupt eine) M. gypseum sensu stricto ist. Das imperfekte Stadium von N. fulia ist M. fulvum Uriburu, welches bis jetzt als Synonym von M. gypseum betrachtet wurde.Keywords
