640 Chondrie^. Coeloclonmm. 



» midia singula obovato-pyriformia foventia. Spliwrosporce 

 ramulis immersse, aggregatse, triangule divisse. 



Species, quas huic generi adnumero, sunt quasi Halyme- 

 nise, fructu Chondrise. Frons proprie tubulosa, tubo filis di- 

 stento; juvenili setate stratum corticale est monostromaticum 

 cellulis cubicis; lila infra hoc 3-polychotoma, ramis patentis- 

 simis, celhilas periphericas suftulciunt. Sed in nonnullis spe- 

 ciebus infra stratum corticale hla multiphcantur et demum 

 stratum intermedium formant, quasi celhiHs irregularibus con - 

 stitutum. Hoc quoque statu celhilse corticales forma ab inter- 

 medio strato facihus distinguantur. Celhihs corticahbus cu- 

 bicis et monostromaticis ab Er^^throclonio et llhabdonia ste- 

 riles quoque dignoscantur. 



Structura nuclei Genus Chondrieis pertinet; fila gemmi- 

 diifera elongata a plexu placentari sui-gunt, tela arachnoidea, 

 inferne prsecipue mihi conspicua (at revera ad carpostomium 

 ducente?), cincta; in articuhs terminalibus majoribus, omnino 

 invicem hberis, gemmidia pyriformia formantur. 



* Fronda articulato-constrida.
