An authentic specimen from Curtis (B. M. 994) has too little left 

 for identification, yet some spores and a fragment of sporangium 

 which were scraped off were identical with a good typical specimen in 

 Strassb. Herb., sent by Prof. Parlow from Curtis's original gathering. 



In the type specimens of both Badhamia Alexandrowiczii Host, and 

 Didymium reticulatum Berk. & Br. (B. M. 574), the sporangia are 

 slender, rugose, yellow plasmodiooarps, having Badhamia-like capillitium 

 with few hyaline threads, the spores 10 to 12 fi diam. ; they closely 

 resemble the common North American form which appears in the 

 Schweinitzian collection under the name of Cimkmoshia reticulata 

 Rost. In these American specimens the capillitium has large, 

 branching, pale-yellow lime-knots sparingly connected by hyaline 

 threads. Spores 9 to 11 /i diam. Badhamia chrysotricha Rost. difFers 

 from the last only in the more completely Badhamia-like capillitium 

 and the rather larger spores, measiu-ing 11 to 13 fi.. 



Hah. The original specimen was found on the trunk of a living oak. 

 It is found also on dead wood, moss, etc. — Poland (Strassb. Herb, 

 and L:B.M.5 slide) ; Ceylon (B. M. 574) ; Pennsylvania (L:B.M.5) ; 

 S. Carolina (B. M. 994). 



5. B. magna Peck, in Rep. New York Mus.,xxxi., p. 57 (1879). 

 Plasmodium? Sporangia globose, 1 mm. diam., violet-grey, the 

 surface wrinkled, iridescent, clustered on long membranous 

 yellowish slender branching stalks, 4 mm. long or more ; 

 sporangium-wall with scanty deposits of lime. Columella none. 

 Capillitium as in B. hyalina Berk. Spores purplish-black, darker 

 and minutely spinulose on one side, almost smooth, not clustered, 

 9 to 10 /u, diam. — B. varia Mass., Mon., p. 319 (in part). 



Plate II.,' B.—a. sporangia, x 20 (Vermont : Peck's type) ; b. spores, 

 x 000. 



This species has been recorded only from America, and is represented 

 in the collection by a mounting from Peck's type ; it is nearly allied 

 to B. hyalina Berk. 



ffab. On dead wood.— Philadelphia (L:B.M.6). 



6. B. macrocarpa Rost., Mon., p. 143, figs. 118, 120, 121 (1875). 

 Plasmodium? Sporangia sessile, subglobose, aggregated, or 

 stipitate, gregarious, 0-5 to 1 mm. diam., white, rugose; 

 sporangium-w.all membranous, varying in the amount of innate 

 lime-deposits. Stalk when present erect, about 0-7 mm. long, 

 0-1 mm. diam., tlicker above and below, furrowed, yellowish-
