— Caespites depressi, expansione 2-3 cm., inferne irregulariter di- 

 ehotomse nudiusculse, superne ramos, apicem versus sensim brevio- 

 res, subsecundos vel vagos einittentes. Articuli diainetro 4-10-plo 

 longiores, inferne magis cylindracei, superne geniculis eximie con- 

 tractis magis oblongi, superiore apice ramigero infiato ; fructigeri 

 eximie piriformes, infra apicem ramuloruin siti et articulo unico 

 ampullseformi vel sa^pius ramo, articulis 2-3 constante, coronati, 

 tetrasporangia in sinu inter articulos infiatos relicto gerentes. In- 

 volucrum paulo infra apicem articuli piriformis egrediens et ge- 

 niculum verticillo ramellorum cingens, ramellis simplicibus incur-

 giata, segmentis erectiusculis; articulis superioribus oblongis dia-

— Casspites hemisphsericij densissimi, purpurei, 3-4 cm. longi. 

 Frondes seta porcina crassiores, decomposito-dichotoma?, fasti- 

 giatae, moniliformiter contractae. Articuli inferiores cylindracei ad 

 genicula contracti, superiores oblongi, ramum sustinentes subpi- 

 riformes, omnes diametro 3-4-plo usque 8-plo longiores. Rami fer- 

 tiles paucis articulis constituti; ramuli nempe lateralis abbreviati 

 articulus prenultimus plerumque fertilis evadit, ultimo articulo ab- 

 breviato coronatus ; articulus fertilis, qui ssepe in ramulo est in- 

 fimus, piriformiter infiatus, infra geniculum ramellos involucri 

 ineurvos abbreviatos emittens, tetrasporangia in sinu inter utrum- 

 que articulum gerens. Habitu hrec species fere Griffithsiam Schou-
