This is a most singular fungus, and but little of it was found. The eapilli- 
-tium though abundantly charged with lime granules, does not appear to have <3 we 
_ them continuous throughout its whole extent, and the plant would, therefore, aA 
seem to belong to the genus Physarum. On the other hand, the larger 
bodies which I have regarded as spores, give indications that they may be > 
really an investing membrane, which encloses the true spores, for they are — 
often found ruptured, though I have not been able to see them dischaneneal 
spores or containing them. ‘They are colored like the spores, and there are 
all manner of intermediate sizes between the largest and smallest. It thus 
appears to be neither a good Physarum nor a good Badhamia, though with © 
close relations to both. For the present, I leave it in the genus Physarum. —

have a discoid columella, but as its capillitium is said to be brown, it is prob-
