Described from islands in the Pacific ocean and apparently of 
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.

pl. 8. 1901. 
This plant was collected by M. Lionnet on trunks in the isth- 
mus of Panama. It is closely allied to £&. 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, 8x 5. Several 
specimens are in the New York Botanical Garden collected by C. 
L. Smith in Nicaragua.
