Growing on old bark, herbaceous stems, etc. Sporangia .4-.8 mm. in diameter, sometimes by confluence larger. This species seems near _Badhamia verna_ Smfdt, but the latter everywhere is described as sessile, while in the former the short black stipe is nearly always distinguishable. 5. BADHAMIA AFFINIS, Rost. Sporangium hemispherical, or much depressed, the base flattened or umbilicate, stipitate, erect or often cernuous; the wall a thin pellucid membrane, coated with minute white granules of lime, which are frequently 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 abundant. The spores are very large, in some specimens averaging 17 mic. 6. BADHAMIA DECIPIENS, 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 network, 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 determined 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 chrysotrichum_, 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 present 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 loose net-work of rather small meshes, with wide expansions at the angles; the tubules filled with white granules of lime, sometimes confluent toward the base of the sporangium. Spores subglobose, very minutely warted, dark violaceous, 11-14 mic. in diameter.
