developed. There is also a bit of this from Schweinitz in the 

 Curtis Herbarium which shows the same spores. In the same 

 herbarium is a good plant from Hillsboro, N. C, without specific 

 name, but pinned on the same sheet with C. aurca. It looks much 

 like C. gelatinosa with the same dark, rather olive tint. The 

 spores are a little larger and hardly so rough as in our plants, 

 3.7-4.8 x 8-11 [x. Cotton has shown (confirmed by us) that Per- 

 soon's type plants of C. grisea are C. cinerea (Trans. Brit. Myc. 

 Soc. 3: 184. 1909) as Persoon himself stated in 1822. It is pos- 

 sible that our plant exists in Europe and is the one that Fries 

 erroneously interpreted as C. grisea.

Plants of medium to large size, up to 15 cm. high and 12 cm. 

 broad, usually about 8-10.5 cm. high and same breadth; stem dis- 

 tinct, usually stout, short, glabrous, whitish, then tan or leather 

 color, and often stained with deep, dull vinaceous rose color ; 

 branches delicate, very numerous and loosely crowded, spreading 

 on the sides, terete or channelled, quite rugose, or at times not at 

 all so, branching irregularly and ending in short, bluntish cusps; 

 color light tan when fresh, the tips concolorous when very young 

 but soon becoming pale rosy vinaceous then darker vinaceous and 

 finally deep dull brick-brown. Flesh white or often stained
