82 Synopsis of the Bacteria and Yeast Fungi. 



considers truly enough, that this is more closely related 

 to the formation of spores in the sporangia of Thamnidium, 

 Chaetocladium, and Choanephora, than in the asci of the 

 Ascomycetes, and that it is exactly paralleled by the forma- 

 tion of zoospores in the conidia of some species of Perono- 

 spora and Cystopus, and that similar phenomena are met 

 with in the Gymnoasci. 



With respect to the physiological character of exciting 

 alcoholic fermentation, Brefeld says very little, but since 

 the Mucor-ferment as well as other Fungi is said to possess 

 the same property, it would seem, if all these considerations 

 prove to be true, that the Saccharomycetes will have small 

 claim to autonomous rank. To what species, however, 

 if any, they must severally be attached, as budding conidia, 

 remains to be determined. For the present, all this is mere 

 speculation, and the only philosophic course is to treat 

 them as independent Fungi, until the contrary is fully 

 demonstrated. The authors who jumble up together Micro- 

 coccus, Mucor, Ustilago, Penicillium, Aspergillus, Oidium, 

 Torula, and Saccharomyces are not the true friends of 

 scientific progress.
