title: [Morpho-biochemical differences observed on two wild strains groups of Cryptococcus albidus: V. albidus and V. diffluens (author's transl)].
abstract: The morpho-biochemical characteristics were studied on 115 wild strains of Cryptococcus albidus: 61 isolates of the variety albidus and 54 of the variety diffluens. The mucous aspect of the colony, the pigmentation, the development on liquid medium, the cells' form and the filamentation were the morphological characters observed. As for the physiology, were reported the results concerning: the fermentation, the assimilation of 24 carbohydrates and the potassium nitrate, the development according: the temperature, two rates of actidione (cycloheximide) and four rates of tetrazolium. Were discussed: the atypicity and the intra-specific variations, the differenciation of the varieties and the taxonomic value of the two entities.
