1848. Physarum decipiens Curtis, Am.Joitr. Set., VI., p. 352. 

 1873. Badhamia decipiens Berk., Grev., II., p. 66. 



Sporangia gregarious, depressed-spherical or ovate, sessile, 

 occasionally plasmodiscarpous, dull yellow, roughened by the 

 rather large, numerous, calcareous scales ; columella none ; 

 capillitum dull orange, strongly calcareous, only slightly widened 

 at the nodes ; spore-mass black ; spores pale violet, minutely 

 spinulose, 10-12 /u,. 



Among Badhamias this species is at once distinguished by 

 its color. If the brief description (Grev., II., p. 66) can be
