layer and is everted, the points of the rays remaining attached to the 
points of the outer cup-shaped layer. The inner peridium is globose 
and borne aloft as usual. When fully expanded the inner surface of 
the outer peridium has a white or flesh colored tinge, and under the 
lens is minutely granular. The inner peridium and area about the 
mouth is white, while the other portion is whitish or pale lead color. 
By the time the perforation appears at the center of the mouth the 
inner peridium is 2.5-3.5"" in diameter and is sessile or only very 
slightly pedicellate. 
The cup-shaped outer layer of the outer peridium is quite distinct 
and well formed, although it is quite firmly attached to the moss and 
bark and is very thin, the margin of course being split into a number 
of rays corresponding to the rays of the inner layer. 
At my request Mr. J. M. Van Hook, assistant in the botanical 
cepartment, photographed the plant, one photograph being taken with 
the plant enlarged two and one-half times to show more of the detail, 
while another photograph was taken natural size (fig. 7). The cup- 
shaped outer layer of the outer peridium, while intact, does not show 
very well in the photograph, because, being almost completely 
immersed in the moss, it could not be sufficiently lighted and brought 
into focus, though in one of the individuals, which was more or less 
removed from the moss, the outer layer being torn apart shows more 
distinctly. 
The capillitium is white or pale yellowish, or pale yellowish-brown. 
It extends from the inner surface of the inner peridium toward the 
center. The threads are nearly 
straight, or very flexuous and irregu- 
lar, the larger and more irregular 
ones being nearer the peridium. The 
threads are often flexuous and 
branched, but are sometimes un- 
branched for long distances. Their Fras Spores antk threads of

often very irregular and more or less 
corrugated. They vary in diameter from 2-6. ‘The spores are very 
minute, 1.5—2.5 in diameter, white or very pale yellowish-brown, not 
echinulate nor tuberculate, many of them showing that they are more 
or less irregular and sometimes rather strongly angular. 
Dr. Coker has furnished me with an interesting note concerning 
the habitat and collection of the plant, which I append here:
