 ovata, hand acuminata, obtusa vel subacuta, concava, subecostata, 

 marginibus planis, integerrimis. Cellulae superiores peranguste 

 lineares, parietibus tenuibus basin versus vix mutatae, infimae 1 

 ad 2 seriebus multo laxiores, ovatae, pellucidae. Alares, nisi 

 saepe cellula singula inflata ad angulum decurrente, vix distinctae. 



Autoicum. Seta plus minusve 1 cm. ad 1.25 cm. alta cras-
