BADHAMIA 35 



globose, .5-1 mm. in diameter, yellow or greenish yellow, rugulose, 

 sessile ; capillitium yellow, forming an open net with occasional thick- 

 enings at the nodes ; spores clustered, delicately roughened, violaceous- 

 brown, 10-12 II. 



This much resembles the preceding species except in the clustered 

 spores, and more commonly aggregate habit. The spores, as usual 

 when clustered, are conspicuously echinulate on the outer side. This 

 did not escape the notice of the author of the species, op. cit. 



Colorado, Oregon. Reported from West Indies, Ceylon, various 

 parts of Europe.

Sporangia gregarious or aggregated in closely compacted clusters, 

 globose or hemispherical, sessile, the peridium thin, transparent, 

 thickly dotted with white calcareous scales; stipe none; columella 

 none, although a pseudo-columella sometimes appears, formed by a 

 more dense development of the capillitium near the centre of the 

 sporangium below ; capillitium abundantly developed, quite uniformly 

 thickened, but showing an occasional delicate connecting thread, the 

 nodes also somewhat flattened and enlarged ; spore-mass black ; spores 

 by transmitted light, bright violaceous-brown, minutely roughened, 

 10-13 /x. Plasmodium is said to be white. 



In America this seems to be a purely western species. Specimens 

 are before us from western Iowa and from Colorado, South Dakota, 

 Nevada, and Southern California. It is very well marked, though 

 liable perhaps to be mistaken at first sight for sessile phases of P. 

 notabile or P. cinereum. The capillitium is, however, at once deter- 

 minative. Colorado; Bethel. Europe generally.
