Note 62 — Chapter IV · The Growth of Different Organisms in a State of Purity: Their Autonomy.[49]

Since writing the above we have experienced some doubt as to whether the forms of development represented in Fig. 20 are actually those of the aspergillus glaucus, which we supposed our fungoid growth to be. In some of the later sketches of our observations we find similar forms, which belong to a bluish kind of penicillium, with rather large spores. Fortunately, this doubt affects our argument in no essential particular. It matters very little what variety of fungoid growth it is that gives rise to alcoholic fermentation attended by peculiarities of shape that only occur in the development of its spores when air fails it.
