This species is not found often, but when once located is in 

 fair abundance, the aethalia materializing all at one time. It is 

 usually found in wet spagnum swamps, the plasmodium appar- 

 ently vegetating in the substratum beneath the water, and rising 

 to fruit on the tips of mosses and other plants. The normal color 

 is yellow from yellow lime deposited on the outside of the aethalia. 

 The grayish color is due to the absence of some of the yellow lime 

 washed away by water while the aethalia are forming. There is 

 no definite cortex, and the surface is almost smooth, although 

 usually showing the circular indentations of the tops of the com- 

 ponent sporangia. The aethalia are small, the majority 1 to 3 

 cm. across.

Plasmodium? Aethalia pulvinate, 15 to 40 mm. diam., with 

 a thick, white, spongy cortex, white or yellowish below; walls of 

 the closely convolute sporangia membranous, charged throughout 

 with lime-granules, 1.5-2 ix diam. Capillitium scanty, somewhat 

 Badhamia-\ike, with few hyaline threads connecting the branching 

 lime-knots to the walls. Spores spherical or slightly ovoid, dark 

 purplish brown, 12-24 n diam., roughly tuberculate, the tubercles 

 sometimes arranged in irregular lines. 



Type locality: Colorado. 



Habitat: On dead wood. 



Distribution: Colorado, Florida, Guatemala, Nebraska, 

 *New Mexico.

Sturgis gave the size of the aethalia as 15-40 cm. diam., and 

 this has been repeated by subsequent authors. The two type 

 specimens measure respectively 15 and 40 mm., and other speci- 

 mens are within that range. It is probable, therefore, that the 

 designation in centimeters was an error. The species has been 

 rarely collected. The large, dark, rough spores are characteristic.
