98 TWENTY-SEVENTH REPORT ON THE STATE MUSEUM. 

 POLYPORUS V0LVATUS 71. Sp. 



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, minute or punctiform, the mouths yellowish with a tinge 

 of cinnamon ; flesh white ; spores elliptical, flesh-colored, 

 .0003'- .00035' long, about .0002' broad.

This is a small species, rarely attaining a diameter of one 

 inch, but vary 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 Placodermei. *
