Frons carnoso-cornea ex tereti compressa dicliotomo-fastigiata 

 stratis duobus constituta: interiore filis ramosis et reti- 

 culatim anastomosantibus ; exteriore filis verticalibus mo- 

 niliformibus muco solidescente cohibitis constante. Cy- 

 stocarpia certis locis aggregata plurima, in cryptis ssepe 

 pluriseriatis, intra stratum corticale excavatis et seceden- 

 tibus filis apertis, nucleum adparenter simplicem, strato 

 proprio circumnucleari, filis reticulatim anastomosantibus 

 ad carpostomium conducentibus constituto, cinctum fo- 

 ventia; nucleus a plexu filorum interiorum sensim trans- 

 mutato ortus, cellulis matricalibus pluribus certo ordine 

 vix dispositis, demum gemmidia plurima minuta rotun- 

 dato-angulata, gelatina ambiente sine ordine conspicuo 

 cohibita, fovens. Splicerospiorce inter fila corticalia sub- 

 nematheciose evokita densius sparste, oblongse, cruciatim 

 divisa^ 



Fila interiora plurima longitudinaliter excurrunt, unde 

 sectione transversali plurima tantum transsecta adpareant; 

 longitudinali sectione fila in rete areolis elongatis anastomo- 

 santia cernuntur; superficiem versus utraraque arese retis bre- 

 viores, latitudine longitudinem subsequante, donec extimse fila 

 verticalia strati corticalis sustinent. 



Fructus utriusque generis certis locis adproximati viden- 

 tur; cystocarpia ssepe in segmentis supremis, levi strictura 

 separatis, provenientia vidi, quasi in cryptis numerosis, inter 

 fila elongata strati corticalis excavatis, et secedentibus filis 

 demum apertis formata; juvenilia intra ipsum stratum corti- 

 cale inchoantia, filis minutis moniliformiter articulatis a cel- 

 lula pauUo majore placentari provenientibus constituta; hoc 

 stadio cellulam placentarem, fila gemmidiifera emittentem, 

 plantse Nematospermese fere referentia; sed fila hsec elon- 

 gantur, anastomosibus junguntur, et stratum circumnucleare 

 ad carpostomium conducens demum etficiunt; supra nodum 

 basalem hujus strati nucleus maturus adfixus, constans con- 

 gerie gemmidiorum, gelatina communi cohibitorum. Cellulse 

 matricales numerosse, singulse gemmidia phira generantes. 

 Gemmidiorura nucleo deraum expulso, placentaris adparatus
