Fuci, Ilypnec, Conferoce, Borynce, Tham nophorce, Alsidii, Hy- 

 pnothalice et Ilutchinsice sp. auct. — Frons erecta, filiformis, valde 

 lateraliter (quoquoversum) ramosa, articulata (axi centrali grosse- 

 articulato) at sensiin corticata cellulis minutis, aliis articulos, aliis 

 genicula obducentibus, omnibus demum in corticem inordinatum 

 conjunctis, ramellis articulatis, saepius ad geuicula subcorticatis, 

 raro per articulos quoque cortice obductis, deciduis, plus minus 

 densis instructa. Cystocarpia in vertiee ramuli terminalia, ramellis 

 supremis nunc suffulta, bi-triloba, intra pericarpium (articulis 

 terminalibus filoruin a placenta radiantium formatum) nucleolos 

 plures, filis radiantibus separatos foventia; nucleoli filis fasciculatis 

 a placenta basali radiantibus articulatis orti, in articulis superio- 

 ribus carposporas conglobatas muco solidescente cohibitas gene- 

 rantes. Tetrasporangia ad genicula singula aut plura saepius inte- 

 riore latere ramellorum obvenientia, morphosi cellularum cortica- 

 lium formata, spha^rica, triangule divisa. A.ntheridia crustas plus 

 niinus expansas efficientia. 



Obs. Frondes ca^spitosse, a callo radicali aut radice fil)rosa 

 plures, teretiusculae aut compressa', lateraliter quoquoversum ra- 

 mosa; aut distiche subpinnatae ramellisque subheteromorphis ver- 

 ticillatis aut quoquoversum vagis vel a margine frondis compressae 

 distichis obsit;e. Ramelli piliformes, tenuissimi aut firmiores, arti- 

 culali, inonosiphonii et nudi aut demum ad genicula fasciati stra- 

 toque cellularum corticalium instructi, plurimi decidui, nonnulli 

 increscentes, cortice crassiori obducti, sensim in ramulos ramosque 

 abeuntes; apices ramellorum in acumen producti aut obtusiores, 

 nunc in mucrones 2-3 divaricatos aut retrorsum uncinatos excur- 

 rentes; mucrones subhyalini. Cellulae corticales minutas, subrectan- 

 gula; aut hexaedrae, demum magis irregulares. Articuli ramellorum 

 diametro aequales aut 2-6-plo longiores, in ramulis ramisque bre- 

 viores, in illis endochromate colorato tincti, in his nunc monosi- 

 phonii, nunc (in ultimis speciebus) ipsi cellulosi. Cystocarpia trans- 

 formatione ramuli formata, in pedunculo brevi terminalia ramel- 

 lisque brevioribus paucis involucrata. Pericarpium rotundatum aut 

 transversaliter oblongum bi-multilobum, cellulis angulatis subhyali- 

 nis conflatuin, clausum, cellularum dissolutione [?J demum apertum. 

 Nuclei plures eodem pericarpio inclusi, circa placentam centralem 

 dispositi. Placenta centralis pedunculum continuans ct ad apicem 

 cystocarpii (sa^pe inter lobos subinflatos dcpressum) extensa, filis 

 densis dichotomo-fastigiatis et anastomosibus conjunctis contexta.
