32 ENDOSPORE.E. [BADHAMIA. 



growths, tliough all were cultivated from one original gathering of 

 plasmodium, but they were never free as in B. macrocarpa. In some 

 specimens in the Strassburg collection the spores show but slight 

 indication of clustering, in others this character is well marked. 



Hob. Plasmodium extensively creeping over the bark of fallen trees, 

 logs, etc., feeding on effused fungi, especially Stereum hirsutum and 

 Polyporus ver si color. Batheaston, Somerset (B. M. 103) ; Lyme Regis, 

 Dorset (L:B.M.3) ; Glamis, Forfarshire (B. M. 149) ; France (Paris 

 Herb.) ; Germany (Strassb. Herb.) ; Italy (K. 165) ; Massachusetts 

 (L:B.M.3). 



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

 Plasmodium yellow. Sporangia sessile, subglobose, gregarious or 

 clustered, or elongated plasinodiocarps about 1 mni. diam. ; golden 

 yellow, rugose, or greenish with yellow warts and ridges ; 

 sporangium-wall membranous with innate clusters of yellow 

 lime-granules. Columella none. Capillitiuin 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 sparse. Spores purple-brown, in close 

 clusters of 6 to 10, minutely spinulose, coarsely warted on the 

 outer third, sometimes nearly free and scarcely warted on one 

 side, 10 to 13 /x diam. Eost., Mon., App., p. 3 ; Cooke, Myx. Brit., 

 p. 81 ; Mass., Mon., p. 324. B. pallida Berk., in Trans. Linn. 

 Soc., xxi., p. 153. B. inaurata Currey, in Trans. Linn. Soc., 

 xxiv., p. 156. B. papaveracea Mass., Mon., p. 323 (in part). 



Plate III., A. a. group of sporangia, x 20 ; b. capillitinm with attach- 

 ments to the sporangium-wall, x 280 ; c. cluster of spores, x 280 ; d. 

 spore, x 600. 



Examination of the type specimens of B. nitens and B. pallida of 

 Berkeley, from the Rev. C. Badham (Kew 1218, 1235), and of B. 

 inaurata Currey (B. M. 151), shows that they are all the same species 

 with yellow sporangium- wall and closely clustered spores coarsely 

 warted on one side. 



Bab. In the substance of rotten wood, creeping on moss, etc. 

 Hitherto found only in England. Lyme Regis, Dorset (L:B.M.4) ; 

 Luton, Beds. (L:B.M.4) ; East Bergholt, Essex (K. 1235, 1241) ; Cray 

 Common, Kent (B. M. 151). 



4. B. decipiens Berk., in Grev. ii. (1873), p. 66. Plasmodium ? 

 Sporangia branching or vermiform plasmodiocarps, occasionally 

 subglobose, 0'3 to 0*4 mm. diam., sessile, gregarious, rugose 

 or nearly smooth, lemon - yellow or orange ; sporangium-wall 

 membranous with innate clusters of yellow lime-granules. 

 Columella none, Oapillitium yellow or pale orange, a coarse 

 network densely charged throughout with lime -granules, or 

 formed of large angular and branching lime-knots with few 

 connecting hyaline threads. Spores violet-brown, spinulose, 

 10 to 13 p diam. Physarum decipiens Curt., in Am. Journ. Sc., 

 vi. (1848), p. 352. P. chrysotrichum Berk. & Curt., in Grev., ii. 

 (1873), p. 66. Badhamia cJirysotricha Host., Mon., App., p. 4.
