From 1 January 2021, in order to export live mycelium to the EU, including all gourmet mushroom spawn, we have to acquire UK government issued phytosanitary certificates for each batch of product shipped.  This is well beyond the scope of our resources. So we will be restricting the sale of products to overseas markets and are in the process of launching a new website and business dedicated to the our customers overseas.
