erect or often cernuous; the wall a thin pellucid membrane, 

 coated with minute white granules of lime, which are fre- 

 quently raised into scales and ridges. Stipe short, erect or 

 bent at the apex, black, expanding at the base into a small 

 hypothallus. Capillitium of thick tubules, forming an open 

 net-work of large meshes, more or less expanded at the 

 angles ; the tubules filled with white granules of lime. 

 Spores subglobose, minutely warted, dark violaceous, 14-18 

 mic. in diameter. 



Growing on mosses and upon the bark of maple trunks. 

 Sporangium .6-1.0 mm in diameter, the stipe about the same 

 length. Rostafinski's description is based upon a specimen 

 found in Chili, South America, by Bertero ; it is recorded in 

 this country by Peck. I find it in some seasons quite abun- 

 dant. The spores are very large, in some specimens averaging 

 17 mic. 



6. Badhamia dkcipikns Curtis. Sporangia gregarious, 

 sessile, globose, oval or oblong, by confluence sometimes 

 more elongated ; the wall a somewhat thickened and firm 

 yellow or yellow - brown membrane, covered with large, 

 thick scales of lime, tawny to golden yellow or orange in 

 color. Capillitium of thick tubules, forming an open net- 

 work, more or less expanded at the angles; the tubules filled 

 throughout with yellow granules of lime. Spores globose, 

 very minutely warted, lilac, 10-12 mic. in diameter. 



Growing on old wood and bark. Sporangia .6-1.0 mm. in 

 length by .6-7 mm. in thickness. My specimens were deter- 

 mined by Dr. George A. Rex by comparison with a specimen 

 from Curtis in the herbarium of the Philadelphia Academy 

 of Sciences. This species should not be confused with what 

 we have described as Physarum serpula. Physarum chryso- 

 trichum B. & C, is no doubt the same thing. Badhamia nitens 

 Berk., which is also golden yellow, has not yet been found in 

 this country ; it will readily be distinguished from the pres- 

 ent species by its clustered spores. 



7. Badhamia panicea Fr. Sporangia sessile, subglobose 

 or oblong, more or less irregular, gregarious; the wall a thin, 

 pellucid membrane, covered with large, irregular, very thick, 

 white scales of lime. Capillitium of thick tubules, forming a
