The peculiar character of this genus is that the granules of 

 lime are distributed along the whole interior of the tubules 

 of the capillitium ; this makes the net-work rigid, and on this 

 account a firmer support for the wall of the sporangium. 



1. Badhamia capsulifkra Bull. Sporangia subglobose 

 or obovoid, sessile, on a thin pallid or yellowish hypothallus, 

 which sometimes sends out narrow bands or strings of mem- 

 brane of variable length, bearing sporangia singly or in 

 clusters. Wall of the sporangium a thin pellucid membrane, 

 mostly even or somewhat rugulose and iridescent, coated by 

 a very thin layer of white granules of lime. Capillitium of 

 rather slender tubules, forming an open net-work of very 

 large meshes, only slightly expanded at the angles; the 

 tubules coated within by a very thin layer of white granules 

 of lime. Spores subglobose or obovoid, adhering together in 

 clusters of six to twenty or more, distinctly warted on the outer 

 exposed surface, dark violaceous, 10-13 m i c - i* 1 diameter. 



Growing on old bark, leaves, etc. Sporangia .8-1.4 mm. in 

 diameter. Badhamia hyalina and B. capsulifera of Rosta- 

 finski's monograph are here included together; he distin- 

 guished the former by the "sporangia in clusters always 

 exactly globose," a distinction first made by Chevallier; 

 otherwise the characters are the same in both. 



2. Badhamia utricularis Bull. Sporangia subglobose 

 or obovoid, sessile, on a thin pallid or yellowish hypothallus, 

 which often separates into narrow strips and strings of mem- 

 brane of variable length, bearing the sporangia singly or in 

 clusters. Wall of the sporangium a thin violaceous mem- 

 brane, rugulose and iridescent, shining with purple, blue, and 

 violet tints, with a thin layer of white granules of lime. 

 Capillitium of thick tubules, forming an open net-work of 

 large meshes, more or less expanded at the angles, the tubules 

 coated within by a thin layer of granules of lime. Spores 

 subglobose. minutely warted, dark violaceous, 10-13 mic. in 

 diameter. 



Growing on old wood, bark, herbaceous stems, etc. Spo- 

 rangia .5-1.0 mm. in diameter, usually growing in clusters, 

 sometimes suspended by the strings of membrane. Rosta- 

 finski's distinction between this and the preceding species in
