Abstract

A range of variations in colony characteristics and microscopical morphology of Emmonsia crescens Emmons & Jellison 1960 have been studied. A total of 13 strains of the mycelial stage of the fungus were examined in detail. The isolates originated from the lungs of 8 species of wild mammals collected in Czechoslovakia, Bulgaria, France and U.S.S.R. According to their colony appearance the strains were classified into 3 groups as follows: powdered, floccose and fluffy. The microscopic structure of the colonies was relatively unique, differences were found in the size of aleuries and the type of their walls. The morphological variability of E. crescens was not markedly influenced by host species or geographic origin of strains.
