Prof. Fischer still treats Algoe and Fungi as two entirely distinct series developed in parallel 

 rows ; while I suppose that in each class Fungi have diverged as ramifications from various types of 

 Algae : there are other important differences between our systems in the position of the Myxomy- 

 cetes, Coleochgeteas, and Characeae. But, with the exception of these differences, the main point is 

 the agreement of our views with respect to the establishment of four classes which serve equally for 

 Fungi as for Algae.
