The two British species form dense tufts composed of 

 equal, thread-like branches, distinguished amongst the 

 Clavariei by the cartilaginous substance, especially when 

 dry, and in this character agreeing ■with the Tremellineae, 

 but distinct from the latter in the basidia producing four 

 sterigmata at the apex, which support the spores. 



Pterula subulata. Fr. 

 Tufts densely branched, branches very slender, equal, not 

 much divided except at the tips, where they divide into
