Flocci erect, simple ; outer membrane 

 tough, inarticulate ; endochrome at length 

 emergent, breaking up into quadriseji- 

 tate spores. — Berk. Outl. p. 327. Ann.

The affinities of this genus are clearly with 

 Torvia, the circumstance of the endosporous 

 mode of fructification being apparent rather 

 than real. The outer membrane is very tougli, 

 and does not break up into separate portio}is 

 with the spore. It is, in fact, a Se^jtonema en- 

 closed in an additional membrane — M. J. B.
