Near Nipliobolus fissus BLUME, but differs from it by the much longer 

 stipes ; also near N. transmorrisonensis HAYATA, but distinguishable from it by 

 the not fringed scales. Also very near C. flocciger BLUME ; (BAKER Syn. Fil. p. 

 351; COPEL. PHILIPP. Journ. Sci. p. 113;) Very probablly identical with it.
