Leigbton's figure represents a globose fruit with a double wall, 

 the inner enclosing the hymenium, and between it and the base "a 

 dirty-white or tartareons mass." The spores according to the same 

 figure are simple, brownish-coloured and ellipsoid, about 0,025 mm. 

 long, 0,012 mm. thick. These characters do not correspond with 

 those given above of the original specimen from Tajlor in the British 

 Museum. The plant in the single specimen seen is associated with 

 Pannularia nigra.
