growths, though 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. 



Hab Plasmodium extensively creeping over the bark of fallen trees, 

 logs, etc., feeding on efEused fungi, especially Stereum Krsutum and 

 Polvporus versicolor.— 'Ba.th.ea.ston, Somerset (B. M. 103) ; Lyme Regis,

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

 Plasmodium yellow. Sporangia sessile, subglobose, gregarious or 

 clustered, or elongated plasmodiocarps about 1 mm. diam. ; golden 

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

 sporangium-wall membranous with innate clusters of yellow 

 lime-granules. Columella none. Capillitium yellow or orange, a 

 coarse network of rugged bands, rarely contracted to form short 

 hyaline threads connecting branched lime-knots ; deposits of Hme 

 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 /A diam. — Rost., Mon., App., p. 3 ; Cooke, Myx. Brit., 

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

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

 Ber]£,eley, 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.

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

 iSporangia 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. Capillitium yellow or pale orange, a coarse 

 network densely charged throughout with lime-granules, or 

 formed of large angular and branching Hme-knots with few 

 connecting hyaline threads. Spores violet-brown, spinulose, 

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