Rhizopus tritici belongs to a large group of organisms, incapable of 
themselves of penetrating the unbroken cells of the epidermis mechani¬ 
cally or of dissolving them with its enzyms. However, after it has once 
reached the tissues beneath the epidermis, it progresses with great rapidity. 
It, like certain other organisms, is characterized by its ability to “act in 
advance” of its growth.
