 ligulate or elliptic-lanceolate, cymbiforra-concave, the apex obtuse, 

 subcucullate, with or without a short apiculus ; nerve purple, vanishing 

 below apex ; at the subdecurrent angles excavate and composed of 

 inflated rectangular hyaline cells, becoming shorter incrassate and 

 hyaline towards nerve, the upper very narrow and linear. Perichaetium 

 pale, on a short non-rooting branch, elongate subvaginant, bracts 

 with a slender nerve, inner apiculate obsoletely sulcate. Capsule 

 cernuous or horizontal, rather small, ovate-oblong or subcylindric, 

 ferrugineo-fuscous, arcuate when dry. Annulus none ; lid acutely
