Colonies of the mutant grown at room temperature did not show the whitish cotton-like morphology typical of the mycelial form of the parental strain. Y-cells were much smaller than those produced by the parent and grew forming chains of different sizes. The main chemical difference in the wall of the Y-form was the replacement of the α-1,3-glucan, typical of the parental strain, by an amorphous 1,3-mannan in the mutant. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-93-2-209
