About this strain
The sheathed woodtuft is one of the tastiest mushrooms growing on wood. It forms dense clusters with honey-brown caps 3–6 cm across that lighten from the centre as they dry — hence the two-tone look and the Latin name mutabilis, “changeable”. Below the ring the stem is covered with small scales. It has a delicate, spicy aroma and is excellent in soups and sauces; the caps are eaten, as the stems are tough.
It can be grown indoors on sterilised sawdust blocks or on hardwood stumps and logs inoculated with plugs — on wood it fruits from spring to late autumn, often for several years. Caution: it is easily confused with the deadly poisonous funeral bell (Galerina marginata), which can even grow on the same wood — only pick mushrooms you can identify with certainty.

Please note: these growing parameters bring together the experience of practising growers — a starting point, not a guarantee of results. Every grow has its own substrate, climate and equipment, and even small differences can noticeably change the yield. Adjust these values to your own conditions.
