Dlaoluea Tliomasll Rex. — Du. Geo. A. Rex presented specimens 

 of Diachcea Thomasii, a species of Jtlyxomycetes recently described by 

 him, and commented upon the variations of the species and its rela- 

 tions to the adjoining genera. 



The specimen's differed in some respects from the original speci- 

 mens from which the diagnostic description had been drawn, making 

 it advisable to supplement that description. 



The new specimens were a part of some recent gatherings made 

 by ^Ir. Lancaster Thomas at the original locality for the species at 

 Cranberry, N. C, in July and August of this j^ear. 



The sporangia of the type specimens were frequently grouped in 

 clusters, but with rare exceptions they grew upon separate stipes.
