dum; sunt nempe cellulse axin monosiphonium articulatum am- 

 bientes aliter dispositae, nec omnes conformes sed in corticales et 

 intracorticales distinctae. Reinbold scrutatus est, observante Oka- 

 mura, specimina juniora, qu.se revera corticem quasi homogeneum 

 ostendunt. Tetrasporangia cruciatim divisa in icone a cl. Reinbold 

 exhibita distinctissime einnguntu r, sed quoad divisionis tetraspo- 

 rangiorum normam typicam expressis verbis dubitat ille auctor, 

 qui sporangia ct triangule et cruciatim divisa se vidisse contendit. 

 Rebus sic stantibus, genus, etsi cum Carpoblepharide attinitate 

 potissimum congruens, sui iuris servandum censui.

 auct. — Frons erecta, filiformis aut compressa, dichotomo-subpin- 

 nata, immerse articulata, ubique corticata, cortice amplo cellularum 

 stratis duobus constante: interiore cellulis majoribus rotundato-an- 

 gulatis, nunc minoribus interspersis, superficiali cellulis minoribus. 

 Cystocarpia ad ramos sessilia, ramellis conf ormibus paucis involu- 

 crata, intra periderma hyalinum carposporas plurimas angulatas 

 foventia. Tetrasporangia in segmentis pamultimis immersa, demum 

 subinordinata, in cellulis infra-superficialibus formata, spluerica, 

 triangule (aut cruciatim '*?) divisa. 



Obs. Frondis compressae linearis dichotomo-decompositne seg- 

 menta flabellatim distiche expausa, tubo articulato percursa, arti- 

 culis rotundato-oblongis, dense corticata, corticis interiore strato 

 cellulis magnis rotundato-angulatis, exteriore cellulis minoribus 

 coloratis constante. Cystocarpia intra involucrum singula, rotun- 

 data, intra membranam hyalinam carpospnras plurimas fovent. In- 

 volucrales rami pauci, plerumque tres, fructum vix supereminen- 

 tes, segmentis conformes. Tetrasporangia secus margincm exterio-
