98 TWENTY-SEVENTH REPORT ON THE STATE MUSEUM. 
PoOLYPORUS VOLVATUS 2. SD. 
Subglobose, fleshy, firm, smooth, flattened behind and 
appearing sessile, but usually attached to the matrix by a 
small point, whitish, more or less tinged with yellow, red or 
reddish brown, the cuticle continuous, completely envelop- 
ing the hymenium like a coriaceous volva, at length ruptur- 
ing below and revealing the hymenium ; pores long, whit- 
ish, minuteer punctiform, the mouths yellowish with a tinge 
of cinnamon ; flesh white ; spores elliptical, flesh-colored, 
.0003’— .00035’ long, about .0002’ broad.

July. -(Plate 2, figs. 3-6.) 
This is a small species, rarely attaining a diameter of one 
inch, but very remarkable for the volva-like prolongation of 
the pileus around and below the pores. When this is rup- 
tured, little heaps of spores are seen dotting its inner sur- 
face. So abundant are these and so protected from the air 
when they fall from the pores, that they sometimes accu- 
mulate in heaps whose altitude much exceeds the diameter. 
The volva does not lie close to the mouths of the pores but 
leaves an intervening space nearly as great as the distance 
from the mouths of the pores to the apex of the pileus. 
The length of the pores generally exceeds the thickness of 
the flesh of the pileus. The form of the plant with the 
volva-like portion cut away is nearly hemispherical. This 
interesting but rare and aberrant species is allied to the sub- 
erose Placodermet.
