Where to purchase germinating fungi?

[smoolae]

Hello!

To this moment I've only done asymbiotic orchid germination but I thought I would also like to try symbiotic.

Where can one today purchase different fungi for terrestrial orchid germination (B1, A36, Q414,...) in the European Union?

I found https://www.ebay.co.uk/itm/326128120392 but importing it from the UK to Estonia would probably be very problematic.

All the best,
Samuli
