Hi all,

If there is anyone that studies Spartina alterniflora root morphology, please 
help!  I can't find any 
information on what look like root nodules on this species.  I have looked at 
many roots of S. 
alterniflora, but have never seen these structures.  They are spherical and 
range in diameter between 
one and three mm, are white to black, and when I dissected one, it looked like 
a sac encasing a 
spongy, white mass.  They seem to only be at the ends of the finer roots.  
There were some oval-
looking structures inside, but also what looked like stringy structures.  You 
will have to excuse my 
lack of correct terminology, but I have never seen these and have no idea how 
else to describe them.  
Could they be housing nitrogen-fixing bacteria, or perhaps these are 
invertebrate root galls?  Does 
anyone have experience with these that can help?

Many thanks, in advance,
