to print. That expectation was not fulfilled, how¬ 
ever, and the sections were not made until after 
the list was printed. It then developed that the 
supposed sori were composed entirely of closely in¬ 
terwoven hpyhae with an outer layer of rind cells. 
A white fleshy fungus growth in the crown of 
Sagittaria is perhaps connected with these jsclerotia. 
I have not seen it in a, spore hearing stage and 
cannot say what it is. I have seen similar sclerotia 
in the culms of Scirpus lacustris, L., Zizania 
aquaiica , L., and Glyceria fluitans, K. Br. 
565. Doassansia sagittaeiae, (West.) Fisch. 
There has been collected near Genoa Junction 
and in small quantity near Racine a Doassansia on 
Sagittaria heterophylla, Pursh,, which differs from 
the ordinary form of this species in the rather large 
sori which are frequently confluent. At both of 
these stations the host grew in the midst of Sagitta¬ 
ria variability Engelm, which was much the most 
abundant but in neither place was I able to find 
the fungus on the latter host. It seems probable, 
therefore, that it is confined to Sagittaria hetero¬ 
phylla. In that case the question will arise as to 
whether it is to be considered a biological race or 
a distinct species. Following the practice which 
has obtained, this would be considered of specific 
importance among the smuts while the treatment 
of the question is different when the rusts are con¬ 
sidered. For the present, I label it forma con- 
fluens. 
566. Bureileta geobueifera, Davis. 
I have been unable 1 to again secure the growth 
described as due to the germination of the spores. 
I suspect that it was adventitious—a contamina¬ 
tion. The character and relationships of this fun¬ 
gus are therefore to be considered as unknown at 
present.
