CLASSIFICATION OF AUAHU J.'l 



2-3 nun. broad, Bub-ventricose. STEM 7 il' cm. Long, ;it firsl ovatelj 

 bulbous then elongated and equally attenuated upwards from the 

 base, hollow, while, al firsl mealy. SPOKES black, 6-8x3 L5 micr. 



The specimens referred to this species are Bmaller than the di- 

 mensions given in the description. Otherwise thej agree with the 

 description in the sense of Saccardo. Massee, British Fungus Flora, 

 Vol. 1. p. 326, gives the spore measurements as II L5x8-9.

PILEUS .5-1.2 cm. high and broad, ovoid or ovoid-oblong, then 

 campanulate (a1 firsl covered with a white mealy veil which later 

 becomes dark and sometimes almost entirely disappears). STEM 

 2.5-10 cm. high, slender, subequal, usually straight above and more 

 or less flexuous below where it is downy. GILLS adnexed. 

 SPORES obliquely elliptical, 8-10x5-6 micr. 



Springing from an irregularly subglobose, rngulose, selerotium 

 which is Mack outside, white inside. On sheep's dung. 



Although nothing is said in the original description about a veil, 

 the type specimens at the New York Botanical Garden still show 

 some of the mealy white covering of the pileus. This planl was 

 firsl found at Ann ArbOT and later in other localities. It was 

 always found growing from selerotia in dung which had apparently 

 been upon the ground for some time, often over winter. These 

 selerotia were repeatedly grown from spores in the laboratory and, 

 after a certain amount of drying out, sporophores grew from the 

 selerotia. \'>y alternately moistening ami drying the selerotia sev- 

 eral crops of sporohores were produced. This planl may be 

 identical with C. tuberosus Quel.
