It is possible to produce basidiocarps of B. edulis in axenic culture.
Use a deep dish or big jar or flask with modified Hagem/Modess medium:

5 g    Glucose
5 g    Malt extract (Difco)
0.5 g  KH2PO4
0.5 g  MgSO4.7H2O
0.5 g  NH4Cl
0.5 ml Ferric citrate (1%)
15 g   Bacto-agar (Difco)
1 l    H2O, distilled
