sketched out the position he believed these two groups should occupy, 
suggesting their affinities; it is interesting to note that this work has 
largely been confirmed by modern workers. 
Brefeld (1883) placed the suborder in the Hemibasidii, for he considered 
its members to be intermediate in position between the Basidiomycetes 
and the Phycomycetes, having arisen from the latter. He considered
