conclusion that, so far, only plurilocular sporanges are known in 
Stictyosiphon tortilis, and that they possess the structure described by 
Wollny. 
It seems strange that on the escape of the spores they should 
leave no trace of this structure behind, since the empty sporanges 
have without doubt only a single chamber, but Reinke explains 
that the intrasporangial net is dissolve on the emission of the
