Summary
The nuclei in germinating spores and growing hyphae ofGeotrichum magnusii andG. candidum have been examined during life and in fixed and stained preparations.
The spores and the cells of the hyphae are multinucleate. The nuclei consist of a dense Feulgen-negative nucleolus surrounded by a less dense shell of Feulgen-positive particles. No membrane was seen at the margin of either living or fixed and stained nuclei. The mass of chromatin and the nucleolus divide at the same time by elongation followed by constriction. Chromosomes could not be detected in either resting or dividing nuclei.
