 Substantia nunc gelatinoscc (GIoiosi()lionia, Nemastoraa, Ilalymenieoe, 

 Gloiocladia), s«pissime carnosae, rarius cliaitaceo-membranaccoe (Ciy- 

 ptonemioe sp). 



Cellularum stratis duobiis contextiTo sunt. Intcrius nunc lilis

 leoe). Stratum exterius verticale aut filis moniliformibus dicliotonio- 

 fastijjiatis (NeraastomeoB, Faucheas etc), aut cellulis rotundato-angu- 

 latis subsimplici serie dispositis (Gasterocarpeoe, Rhizophylleoe, Cry- 

 ptonemias) conslitutura est. In nonnullis celluhe interiores filorum 

 verticalium, exterioribus majores, stratum fere propriura elficiunt 

 (Neraastoraa, Prionitis). Filu verticalia muco laxiori (Gloiosiphonia, 

 INemastoma, Gloiocludia) aut sa?pissime solidescente cohibentur. 



Organa friictilicationis duplicis generis observata fuerunt. 1:0 

 Cystocarpia situ varia; pluiimorum in immutata fronde imraersa aut

 Nemathecioideoe nidulantia (Acrotylus, Pihizophyllis), aut in parte fron- 

 dis transmutata siliquieforini pluriraa conjuncta (Furcellaria). Carpo-
