Plants 1-5 cm., generally 2-3 cm. broad, depressed-globose, conspicuously plicate 

 below and narrowing quickly to a slender pointed root. Cortex light gray at first, 

 turning a deeper gray and often in age with reddish brown colors. Almost as smooth as 

 kid at first, but sooner or later the cortex becomes minutely dotted and cracked and 

 in age wears away irregularly and incompletely as very thin scales. When young the 

 surface may appear minutely fibrous-granular or almost completely smooth. In 

 exposed areas the inner peridium is seen to be smooth and shining, brownish gray and 

 often tinted with the spore color. Gleba changing from light yellow to gray, purplish 

 gray and then deep ferruginous brown or chocolate brown (auburn to chestnut brown of 

 Ridgway). Subgleba small, occupying only the lower fifth or sixth of the plant and 

 composed of large papery cells. When fully grown but still immature plants are cut, 

 water exudes from the surcharged peridium and escapes as drops, and this excess water 

 often water-soaks areas of the surface when the plants are brought in to dry; in these 

 respects behaving exactly like Bovistella radicata, which it further resembles in the long 

 pedicellate spores. Lloyd does not place this species in Bovistella, but it would seem to 

 belong there if his extension of the genus is adopted. 



Spores (of Xo. 715) when mature a deep chocolate brown with faint tint of purple, 

 globose, covered with warts embedded in a clear, amorphous substance, some of the 

 warts extending slightly beyond this substance, giving the appearance of an outer wall 

 with radial pits, 5.5-6.8// thick, with one conspicuous oil drop and a stalk about twice, 

 or rarely nearly thrice, the length of the spore diameter. Frequently the stalk is broken 

 off. When KOH is applied the clear material surrounding the spore swells consider- 

 ably. Capillitium of simple or moderately branched, somewhat irregular and knotted 

 threads tapering at both ends and about 4-5^ wide in middle, occasionally 7/x wide at 

 knotted places. Rarely a short branch is observed on a thread. At a certain stage it 

 can be seen that threads are formed from the sclerotic thickening of certain selected 

 parts of the trama. These were not simple threads at first, but the branches that came 

 from them did not become hard and went to pieces with the spore mass at maturity. 

 The points where these branches joined the capillitium may be detected as knots or 

 short stubs.
