Porcini Colonized Petri Dish (Boletus edulis) — mycorrhizal collector culture

Porcini colonized Petri dish — Boletus edulis for collectors

A sterile Petri dish with living Boletus edulis mycelium on agar. Produced in Italy by Fungaia. Intended for strain maintenance, microscopy and laboratory transfer, not for fruiting.

Boletus edulis (porcini) is a mycorrhizal mushroom. It forms a living partnership with the roots of a host tree (oak, chestnut, beech, spruce, pine). It is not a saprotroph. It cannot be grown on grain spawn, on sawdust blocks, or in a fruiting chamber the way oyster, lion's mane or shiitake are grown. Documented success at producing porcini fruiting bodies in the wild or in a garden from purchased culture is unproven. This listing is for mycology collectors and laboratory study. You may attempt colonization of host-tree seedlings or forest soil as an experiment; there is no promise of mushrooms, yield, or a working mycorrhiza.

What you receive

• One colonized Petri dish of Boletus edulis on agar
• Sealed for shipping, produced in our laboratory
• Species label: Porcini / Boletus edulis

What this is not

• Not a fruiting culture and not a garden inoculant with a guaranteed result
• Will not colonize grain spawn or produce mushrooms in a grow tent
• Not a proven way to establish porcini under trees

Laboratory and experimental use

Keep the plate for collection, isolation work and clean transfers onto fresh agar. Outdoor attempts (host seedlings, forest soil near oak, chestnut, beech, spruce or pine) remain experimental. Success in the wild is unproven. No yield is promised.

Storage

Keep refrigerated, lid sealed, until you work the culture. Sterile technique. For mycological study only. Packed and shipped from Mercato San Severino, Italy. Processing 1–3 days.
