Caespitosum. Caules decumbentes ssepe unciales, radiculis brun- 

 neis villosi, proliferi, et ssepe parce ramosi. Folia siccitate 

 insigniter involuta et incurvata, madore ascendenti-patentia, 

 inferiora oblongo-lanceolata, superiora lineari-lanceolata, lu- 

 ride viridia, subcarinata, marginibus flexuosis involutis, areolis 

 minutissimis, percursa vena fuscescente completa. 



Pericheetialia conformia, interiora minima. 



Seta brevis vix bilinealis lutescens, terminalis si solitaria, si plures 

 terminales lateralesque, siccitate tortilis. 



Vaginula cylindracea. Paraphyses filiformes hyalinee. Pistilla 

 pauca. Capsula exannulata, oblongo-ovata vel cylindraceo- 

 oblonga, lutescens, parietibus tenuibus diaphanis collo con- 

 trictiusculo, ore irregulariter denticulato rubro. 



Columella clavata, inclusa, breviter stipitata basi reliquiis mem- 

 branee internae cincta. 



Sporula rotundata, lsevia, immersa subdiaphana. 



Operculum e basi conica rubra longe rostratum, capsulam paullo 

 excedens, rostro lutescenti acuto, basi conica columellas apice 

 adhaerenti obtrusa. Calyptram non vidi.

Of this very distinct species, I have only seen one capsule before 

 the fall of the operculum. The inner membrane is totally 

 distinct from the capsule, and is connected only with the 

 margin of the much dilated apex of the columella. It sub- 

 sequently seems to become irregularly ruptured ; the base 

 alone remaining, and surrounding the lower portion of the 

 columella. 



Sect. III. — Diastoma. 



Capsula annulata, collo insigniter constricto. Operculum cum 

 columellse apice secedens.
