How to Start It
★ Recommended for beginners
A pre-colonised block fruits in a couple of weeks indoors — the easiest way to grow this unusual mushroom. Keep it humid and out of direct sun.
A striking, shaggy white mushroom that grows as a cascade of soft spines rather than a capped toadstool — prized for its seafood-like flavour. It's grown much like oyster or shiitake: fast on a supplemented-sawdust block (weeks) or slower on hardwood logs (which then crop for a few years). Likes slightly cooler, very humid, still-but-fresh air.

Growing Tips
- 1Lion's mane likes it a touch cooler and very humid — mist around it often, but still give daily fresh air.
- 2It can look slightly pink or fuzzy in dry air (a sign to raise the humidity).
- 3Catch it at the right moment: snowy-white and tight is perfect; yellowing means you've waited too long.
- 4Sawdust blocks usually give two flushes.

When to Pick
Cut the whole 'pom-pom' while the spines are short and white, before they yellow
How to Harvest
- 1Harvest the entire cluster when it's full and round but the hanging spines are still short and pure white — once they lengthen and start to yellow or brown, the texture turns bitter and tough.
- 2Twist or cut it off whole at the base.
