Hymenium strongly marked with narrow, rather sharp, radiating 

 branched ribs. Papillae usually none, but many specimens occur 

 with a few. Stipe short usually, but sometimes well developed, 

 covered with tomentum, as the pileus. 



This is the original species from Rawak and is widely distributed, 

 specimens having been seen from Malay, Xew Guinea, Australia, 

 Philippines, and particularly abundant in Brazil and other parts of 

 tropical America. Usually the plant is entirely free of warts on the 

 hymenium, but I have noted several collections that have a few 

 warts. Thus the specimen at Kew from Brazil (Fig. 523), (Ule No. 12) 

 has distinct warts. The same collection at Berlin has none, accord- 

 ing to my notes. I believe that the next species, Cladoderris elegans, 

 is in reality only an excessively warty form, for while the type forms 

 are so different (apparently) there are many connecting specimens 

 in the museums.

CLADODERRIS MEMBRANACEA is only a thin form of Cladoderris den- 

 Intica, with no difference, excepting it is a thinner plant, with the tomentum pad 

 on the pileus not so thick Several specimens are in the museum from Cuba (Wright, 

 thufrt! , a f tr - P1? America - The P la "t ^ really misnamed, for while thinner 

 than the type form, it is not thin enough to be called a " membrane." (See page 1 1 )
