The paper deals with the taxonomic value of Penicillium nigricans Bainier ex Thom, P. albidum Sopp, P. kapuscinskii Zaleski and P. janczewskii Zaleski, of which the author has isolated a number of strains from soil. As a result of her investigations and in accordance with the nomenclatural rules, Penicillium albidum Sopp is emended and is considered the valid name for this taxon with the other species being regarded as synonyms. The author further discusses the method of conidial formation in all the strains of Penicillium albidum Sopp emend. Fassatiová which she has studied and concludes that the development is mesendogenous.
