and reassumed a horizontal position and with 
the lower edge revolute. The outer surface of 
the pileus is hard, almost cartilaginous, but when 
dried it becomes irregularly wavy. When fresh 
the fleshy body must have been as wide as the 
base of the pileus. This species is unique and 
very distinct. 
Martelli described the drupes as 15-17 mm 
long, but in his life-sized figure he showed them 
as 28-29 mm long. In the lectotype here de- 
scribed, they are 23-26 mm long. Martelli 
retained a portion of Dr. King’s Collector 3,738 
(erroneously as 3,733) with two parts of a leaf 
and 13 loose drupes. These are from 29-33 mm 
long. It would seem that the measurements 
given in his publication were erroneous.
