Abstract
During investigations of soil samples from various districts in the West of Scotland using Vanbreuseghem's (1952) hair-bait method, Keratinomyces ajelloi, Trichophyton terrestre, Microsporum gypseum and Arthroderma curreyi were isolated. These fungi, and Microsporum nanum isolated from ringworm-infected pigs in Kenya, have been studied in culture on unsterilised soil. Descriptions are given of the perfect stages of K. ajelloi and M. nanum which were obtained in soil culture and that of T. terrestre which arose spontaneously in an agar slope culture. It is proposed that the perfect forms of K. ajelloi and T. terrestre be included in the genus Arthroderma Currey as A. uncinatum sp. nov. and A. quadrifidum sp. nov. respectively, and that the perfect form of M. nanum be put in the genus Nannizzia Stockdale as N. obtusa sp. nov. Au cours de recherches qui avaient pour but d'examiner des échantillons de sol provenant de plusieurs régions de l'ouest de l'Ecosse, en employant la méthode de culture sur cheveux de Vanbreuseghem (1952), on a isolé Keratinomyces ajelloi, Trichophyton terrestre, Microsporum gypseum et Arthroderma curreyi. Ces champignons, et M. nanum isolé de porcs infectés de teigne au Kenya, ont été étudiés en cultures sur sol non-stérilisé. On décrit les stades parfaits de K. ajelloi et M. nanum obtenus dans des cultures sur sol et également de T. terrestre lesquels se produisent spontanément chez une souche cultivée sur milieu gélosé. On propose d'inclure les formes parfaites de K. ajelloi et T. terrestre dans le genre Arthroderma Currey comme A. uncinatum sp. nov. et A. quadrifidum sp. nov. respecitivement et que la forme parfaite de M. nanum soit incluse dans le genre Nannizzia Stockdale comme N. obtusa sp. nov.Keywords
