These filaments are straight or coiled and are non-septate. They 

 are attached by disk-shaped holdfasts to the intestinal wall and 

 project as a tuft of white hairs from the anal opening. At matur- 

 ity a series of three or four cylindrical cells of the same diameter 

 as the hypha is formed. These cells appear to be spores. When

 Pajiopeus herbstii. A. Apex of hypha, showing endogenously formed spore.

the apex of the hypha ruptures, the spores are freed seriatim by 

 growth and pressure from below. All efforts to cultivate this 

 organism on artificial media have failed. It is strictly parasitic, as 

 are related species. 



Little is known about the taxonomy and systematic position of 

 Enterobryus, and it is not included in Saccardo's Sylloge Fungo- 

 rum, even though a considerable number of species have been 

 described. The Genus Enterobryus was founded by Leidy (1849, 

 1853) from observations of several entophytous species.
