BOUDIERA. 285 
The soft, fleshy, subgelatinous texture; the papillate 
hymenium, arising from the protruding asci, which are-.. 
always broadly clavate; and the growth of nearly all 
species on the dung of animals, are ready characters by 
which to distinguish the plants of this order from Pezize. 
They rarely exceed 2 lines in breadth, the majority 
being much less.
