Is Calvatia gigantea commonly known to be mycorhizzal with grasses?  

I was recently struck by the appearance of a bright green ring (1 meter
thick, 6.5 meters in diameter) of grass in an otherwise yellowing hay
meadow.  Calvatia gigantea was fruiting, fairy ring fashion, in the green
band.  The fungus was apparently providing something of use to the grass,
and I wondered if there was a mycorhizzal association.
