reticulated on the rounded side, the remaining part marked with 
scattered warts. He gives their size as 6-8/a in diameter. 
Massee describes the color as varying from dull umber, through 
reddish-brown to pale gray with silver lustre. He also speaks 
of the slender anastomosing branches of the capillitium. He 
calls the spores 7-9/a in diameter. 
The one specimen which I have is about an inch and a half 
long, a beautiful silvery-white, cortex slightly roughened. Lis¬ 
ter has described the character of the capillitium as I find it, 
quite exactly. I find the spores as he describes them, appearing 
turbinate in some positions; but the reticulated portion is more 
nearly two-thirds than a half, as given in the original descrip¬ 
tion. The edge of the reticulated portion stands out from the 
remainder of the surface in quite a marked way, as if a part had 
been cut off. I find the spores to be from 7 to 11/a in diameter. 
This specimen was found growing on the bark of an erect 
maple in Madison, October 18. 1901.

Massee gives Wingate’s original description, which I quote in 
part: “iEthalium of irregular shape, globose, ovoid, or round¬ 
ed pyramidal, attached to the substratum by a wide base. Vari¬ 
able in size from 5-30 mm. in diameter. Cortex and mass of 
spores ferruginous brown; occasionally the cortex shining; 
sometimes membranous, pellucid. The walls of the spor¬ 
angia (which form a capillitium) membranous, pellucid, band¬ 
like, combining into an all-sided network attached uniformly to 
all sides of the cortex. The bands have triangular or polygonal 
expansions at the angles where they join each other. Spores 
globose, about two-thirds of the surface covered with a delicate, 
regular, fine-meshed network, the remainder with simple warts 
or elongated ridges. Spores measure 7.5-9/a.” 
Macbride adopts the name given b}' Morgan, E. splendens . 
His description adds to the excellent one given above: “iEtha- 
lium pulvinate, even, or somewhat irregular, unevenly swollen 
or inflated, lobate or compound, covered by an exceedingly thin, 
generally smooth, shining, but never wdrite pellicle or cortex;
