Ulothrix parietina, Ulothrix tenuis, Schizogonium murale 

 and Trasiola calophylla, were found growing together, 

 and upon careful examination they appear very fully to 

 confirm the view of Dr. Braxton Hicks (Quart. Journ. 

 Micros. Sc, 1861 and 1868) that Schizogonium is only a 

 condition of Ulothrix in which the threads have become 

 connate, of which Trasiola is only a frondose form.
