 purple seta, elliptico-cylindric, pachydermous, rufous-brown, when dry 

 and empty, exactly cylindric, slightly arcuate ; lid conic, short beaked,

Much resembling B. fallax in areolation, but known at once by the much 

 longer and less recurved leaves, with smaller less incrassate cells ; it must 

 stand as the type of the species, being more highly developed in all its parts 

 than B. vinealis. 



Var. /3. vinealis [Bnd.) 



Plants shorter, rufo-ferruginous ; leaves shorter. Caps, ovate-oblong 

 with a shorter lid.

Resembling B. fallax, but the obscure small upper cells distinguish it ; 

 these in fallax being pellucid, rounded and much incrassate. 



II. BAEBULA SINUOSA {Wils.) 



Dioicous; densely csespitose. Leaves lineal-lane, cirrate, nerved 

 to apex, margin sinuous in the upper part, toothed at apex, basal cells 

 rectangular. (T. XL, E.)
