in which numerous oval-oblong, bright shining, dirty red- 

 coloured spores arise. (Fig.

This species forms partly little floating scales, partly continuous 

 membranes ; the threads finally dissolve to a jelly, thereby freeing the 

 spores, which then sink to the bottom, united in little gelatinous heaps. 

 The species is easily recognisable by the dirty-red colour of the spores. 



VIII. LEPTOTHRIX, Kutzing ("Phycologia Gene- 

 ralis," p. 198), pro parte. 



Threads very long and slender, unbranched, apparently 

 inarticulate, colourless, without motion, not granular, free or 

 felted together. 



The Fungi assigned to the genus Leptothrix are of very 

 questionable value as species ; I therefore include the fol- 

 lowing with all reserve. Leptothrix-like formations are very 

 common in Bacillus. 



Since this genus will probably remain only a short time among 

 the Fungi, I do not think it desirable to give it a new name now. 

 The greater part of the species of Leptothrix are typical phycochro- 

 maceous Algae ! 



48. L. buccalis, Robin (" Hist. Nat. Vg. Paras.," p. 

 345)- 



Threads very long and slender, 7-1 p. (seldom some- 

 what more) thick, inarticulate, colourless, densely felted in 

 white masses. (See also Fig. 270.)
