Frons eonfervoidea, e filis grosse articulatis ramulos breves op- 

 positos aut verticillatos gerentibus composita, rhizoidibus subcorti- 

 cata. Cystocarpia loco ramulorum in ramis majoribus brevium evo- 

 luta, singula aut bina opposita aut verticillata, coma ramulorum 

 manicae ad instar involucrata. Gonimoblastus unicus, evolutione suc- 

 cedanea in gonimolobos plures rotundatos divisus. Tetrasporangia 

 cruciatim (?) divisa.

 — Frons erecta, teretiuscula, tenui-filamentosa, abunde lateraliter 

 ramosa, ramis virgatim prolongatis, penicillis ornatae. Penicilli 

 ex eodem articulo rachidis extus corticatte gemini (aut ternatim 

 verticillati) oppositi, juveniles tenuiores, adultiores quasi supra pe- 

 dicellum, ramellis a corticali adparatu erumpentibus hirtum densius 

 comosi. Cystocarpia per frondem sparsa, solitaria vel 2-3-nata, 

 brevissime pedicellata, fasciculo denso ramellorum tenuium capu- 

 laeformiter cincta', gonimoblasto unico in lobos plures, evolutione 

 succedanea ortos pedicellatos rotundatosque diviso. Antheridia thyr- 

 soidea, laxe ramosa, parva. Tetrasporangia cruciatim (an etiam 

 triangule ?) divisa, in parte frondis superiore evoluta. 



Obs. Imprimis differt a fere omnibus Antithamnii (excipe A. 

 nodiferum) speciebus, quibuscum tetrasporangiis cruciatim divisis 

 congruere dicitur, filis longitudinalibus secus ramos decurrentibus 

 qnasi adparatum corticalem proprium constituentibus, a quo fila 

 nova demum pullulantia brevissima penicillorum pedicellos obte- 

 gunt: attamen monendum est, quod in icone Kuetzingiana (pro 

 Warrenia comom exhibita) tetrasporangia et transverse bipar- 

 tita et triangule divisa depinguntur; pro Wrangelia comosa te- 

 trasporangia eximie triangule divisa dclineavit ill. Kuetzing. Genus
