of the origin of the Ascomycetes as a whole, and the determination of the course of evolution in the entire 
fungus series: matters which, in recent years, have been too copiously discussed in the rather feeble li<:lit 
of small contributions to the available data. Although it is difficult to believe that the Laboulhenialcs, 
for example, and the Florideae; that Monoblepharw inxignis and Wwdierta inlmnrdia Nonlst; that 
Araiospora and Dichotomosiphon; that the Mycochytridinea\ Rh loc kyi r ium and Chh>n>chytrinm have 
none of them ever had mutual kin nearer than some primordial protoplasmic entity at the bottom of the 
plant series and in the early ages of organic life; it is nevertheless foolish, on the basis of our pre- nt 
knowledge, to attempt an arbitrary settlement of the complex phenomena of s< ries among the fungi. 
As to the Laboulbeniales, it may be said with safety that they n mblc the Floridea* in some resp< < tj 
more closely than they do any other plants, while at the same time they are moi surely A>< omyoetes 
than many forms included in this group, and the writer sees no sufficient reason why they hould not 1m 
placed in the Pyrenomycetes, as a group coordinate with the Perisporiales, IlyjxxTeales etc.
