Described from islands in the Pacific ocean and apparently ot 

 general occurrence throughout tropical America, since most of the 

 collections from that region contain specimens of it. A large plant 

 was collected last year by Percy Wilson in Porto Rico, and Earle 

 on his recent visit to Jamaica found it at three different stations ; 

 at Port Maria on a dead limb of a leguminous tree, at Hope 

 Gardens on a dead deciduous trunk and at Port Antonio on the 

 stump of a hog plum and the fallen trunk of a cocoanut palm.

This plant was collected by M. Lionnet on trunks in the isth- 

 mus of Panama. It is closely allied to E. tornata, but is thinner 

 with a thinner crust, which is usually profoundly wrinkled from 

 the center outward. The context is floccose, elastic, brownish- 

 rufous, and the spores ovoid, smooth, fulvous, 8 x 5 /i. Several 

 specimens are in the New York Botanical Garden collected by C. 

 L. Smith in Nicaragua.
