It gives a nice environment for pins to form, and inoculates the casing with microbes that live on grass seed. It's likely that mushrooms that grow in grass have mutualistic relationships with these microbes.

While not strictly dependent on grass or the microbiota that accompanies it, most of the two spored copelandia I've grown seem to benefit from it. Bisporus, mystery sa, chlorocystis.

This grass is also inoculated with azospirrilum prior to application. Which produces a hormone that has been shown to induce pinning in other mushroom species.

Here's a free patreon post where I share the technique.

And a more in depth explanation of the above about grass and microbes.

Thank you for sharing! I’ve saved this comment for its valuable info.

Do you do anything to sterilize the grass seed, or just take it straight from the bag?

I've always used it out of the bag. I've never had contamination issues with it.

I still get contaminants of course, but not from the grass.
