this is no valid reason for change, we retain Berkeley's specific name, 

 which by general consent has priority.

Sporangia gregarious, subglobose, rugulose-squamulose, 0.6-0.8 mm., 

 sulphur-yellow, stipitate; peridium membranous, covered with cal- 

 careous scales; stipe stout, white, charged with lime, furrowed; col-

The description and figure given by Schweinitz, 1805, leave no 

 doubt as to what he had in hand. Twenty or thirty years later, 

 having spent the interval in this country — bishop, indeed, of the 

 Moravian churches, but a student of fungi all the while — he reports 

 the same thing from this country. Cooke also lists it in Myxomycetes 

 of the United States.

Cooke's original description is as follows: 



"Sporangia globose, depressed, ochrey yellow, covered with orange 

 mealy scales above, with a very short, almost obsolete, stem. Colu- 

 mella not evident. Capillitium strongly developed, expanded at the 

 angles, which are filled with yellow granules of lime, combined into a 

 network; deposits of lime in irregular, angular masses. Spores violet- 

 brown, nearly smooth or minutely warted, .013-015 mm. diam." 



Reference is made to fig. 253 of the same author's Myxomycetes of 

 Great Britain, which merely indicates the depressed globose peridium 

 with a tendency for the lower portion to remain as a cup, and the 

 short, thick stipe. The species is not mentioned in the text. The spores
