Structura cystocarpii Champia a Lomentaria admodum 

 recedit, cum Rhodymeniaceis magis adspectu nuclei maturi 

 conveniens. In Champia vero nucleus cingitur tela arachnoi- 

 dea admodum conspicua et tenaci; quse si analoga quoque in 

 fructu juvenih Rhodymeniacearum existere censeatur, iu ma- 

 turescente fructu tantum ut fila dilacerata paucissima restat. 

 Sphicrosporge magme triangule divisse, aggregata; et quasi 

 sorum formantes, attinitatem cum Lomentariis probantes cui- 

 dam forsaii viderentur. Majori jure hoc resj)ectu Champia 

 et Chylocladia comparantur.
