54 BNDOSPOREAE [BADHAMIA 



5. B. foliicola Lister in Journ. Bot., xxxv. 209 (1897). 

 Plasmodium orange. Sporangia subglobose, 0-5 to 1 mm.' 

 diam., iridescent-grey, sessile and crowded, or standing 

 singly on slender pale yellowish-brown stalks 02 to 0-5 mm. 

 long. Capillitium a network of slender strands with white 

 lime deposits. Spores free, sometimes showing a slight 

 tendency to adhere in loose clusters, violet- brown, minutely 

 spinulose, 9 to 11 ^ diam.— Torrend Flore des Myxomyc^tes, 

 p. 210.* 



PI. 11.— a. sporangia ; b. capillitium and spores ; c. spore ; (England). 



This species is not infrequent in this country, where it sometimes 

 occurs in great profusion on turf, on heaps of old straw or dead leaves, 

 or on twigs. From B. utricularia, to which it is very closely allied,' 

 it is distinguished by the simple stalks, the free and minutely spinulose 

 spores, and by the difference of habitat ; from B. panicea it differs in 

 having orange Plasmodium and rather rougher spores. The descrip- 

 tion of B. microcarpa Schroet. (in Cohn Crypt. Fl. Schlesien, iii. pt. i. 

 131, 1889) would apply to B. foliicola except that the spores are given 

 as measuring only 7 '5 to 9 fx ; in the absence of the type, however, we 

 cannot be sure that this reference is correct. 



Hab. On turf, straw, dead leaves or twigs. — Wanstead, Essex 

 (B.M. 1695); France (B.M. 2067); Switzerland (B.M. 2070); Sweden 

 (B.M. 2068) ; Portugal (B.M. 2069). 



6. B. magna Peck in Rep. New York Mus., xxxi. 57 

 (1879). Plasmodium ? Sporangia globose, 1 mm. diam., 

 violet-grey, iridescent, clustered on long membranous 

 yellowish slender branching stalks 4 mm. long or more ; 

 sporangium-wall with scanty deposits of lime. Capillitium 

 as in B. capsulifera Berk. Spores purplish-black, very 

 minutely spinulose with a paler smoother area of dehiscence, 

 not clustered, 9 to 10 /* diam. — Dictydium magnum Peck 

 I.e., xxiv. 84 (1872). B. varia Mass. Mon., 319 (in part). 



PL 9.— a. sporangia (Vermont, X. York ; Peck's type) ; b. spores. 

 This species has been recorded hitherto from America only. 



Hab. On dead wood. — Maine (B.M. 1585) ; Philadelphia (B M 

 2071). 



7. B. nitens Berk, in Trans. Linn. Soc, xxi. 153 (1852). 

 Plasmodium yellow. Sporangia sessile, subglobose, gregarious 

 or clustered, about 1 mm. diam., sometimes forming plasmo- 

 diocarps, golden-yellow, rugose, or greenish with yellow warts 

 and ridges ; sporangium- wall membranous, with included 

 clusters of yellow lime-granules. Capillitium yellow or orange, 

 a coarse network of rugged bands, rarely contracted to form 

 short hyaline threads connecting branched lime-knots ; 

 deposits of lime usually dense, sometimes scanty. Spores 

 purple-brown, in close clusters of 6 to 10, minutely spinulose,
