No, only commercial. I talked to Fungi Perfecti company about adding them, and they said if they could find a strain, they would add it, so I pointed them to two products, yet they never added it,
Rhizoscyphus ericae. is the one you need, and from the genus Hymenoscypus or other Rhizoscyphus species may help too.
I once found a commercial source, but I can't find it now. It was expensive as they sold only in large amounts for blueberry farmers.
The only product I could find is from another country
Oh I found a US distributor. Expensive! And I'm not sure they actully have the right fungi?
