[MARQAUrrA. 
globose, 6 to 7 /X diam., often irregularly angled from mutual 
pressure, smooth, pale vinous with a yellow tinge. 
Hab. On living fronds of many species of fern and on Tillandsia 
niuscoides. — Argentine Republic. A beautiful but paradoxical species, 
exactly resembling a folicolous JEcidium ; it will probably form the 
type of a new genus. 
From the description of the fimbriate sporangium-wall, mycelium- 
like capillitium threads and angular spores, it is possible that this 
species does not belong to the Mycetozoa. 
EXCLUDED FROM THE MYCETOZOA.
