PI. 5.— a. b. sporangia ; c. capillitium attached to fragment of sporangium-wall 

 and three clusters of spores ; d. spore ; (England). 



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

 East Bergholt, Essex (Kew 1218, 1235), and of B. inaurata from 

 Carlisle (B.M. 151), shows that they are all the same species, with yellow 

 sporangium-walls and closely clustered spores coarsely warted on one 

 side. The type of Didymium, reticulatum Berk. & Br. from Ceylon 

 (B.M. 574) has few spores remaining, but these are loosely clustered ; 

 the specimen is therefore placed under B. nitens.

8. B. versicolor Lister in Journ. Bot., xxxix. 81, 

 tab. 419, 2a to e (1901). Plasmodium ? Sporangia sub- 

 globose, sessile, minute, 0-3 to 0-5 mm. diam., scattered or 

 in small clusters, grey or flesh-coloured, somewhat rugose ; 

 sporangium-wall membranous with scanty deposits of lime- 

 granules. Capillitium a network of broad or narrow strands 

 charged throughout with Ume-granules, white or apricot 

 coloured. Spores ovoid, 10 X 8 to 12 X 9 /*, arranged in 

 clusters of 10 to 40, forming hollow spheres, dull purple and 

 minutely warted at the broad end, nearly colourless and 

 smooth elsewhere. — Sturgis in Colorado Coll. Publ., Sci. 

 Ser. xii. 13 (1907). 



PI. 6.— a. sporangia ; b. capillitium and clusters of spores with some free spores ; 

 c. spore; (Scotland). 



This minute species appears to be allied on the one hand to B. 



capsidifera, and on the other to B. nitens. As yet it has been recorded 



only from two widely separated localities. The Rev. W. Cran has 



found it on about a dozen occasions near Rhynie, Aberdeenshire, 



where it occurred on living trees at a height of five or six feet from the 



ground ; in 1906 the same form was discovered by Mr. E. Bethel on the 



bark of fallen trunks of " box-elder " (Negundo) near Boulder, Colorado. 



Hab. On bark and lichen. — Aberdeenshire (B.M. 1759) ; Colorado

9. B. decipiens Berk, in Grev., ii. 66 (1873). Plasmodium 

 yellow ? Sporangia sessile, subglobose, or forming curved 

 plasmodiocarps 0*3 to 0-7 mm. diam., scattered, rugose or 

 nearly smooth, yellow or orange; sporangium- wall membranous 

 with included clusters of yellow lime-granules. Columella
