Treasure Coast is a cultivar of the magic mushroom Psilocybe cubensis, named after the stretch of Florida's Atlantic coast where a Spanish silver fleet was wrecked in 1715. Dutch-Smart describes it as wild-collected in that region, fast to colonise and relatively potent. Who first collected it has never been documented, and no laboratory has published its psilocybin content. This site sets out what is known, what the shop says and where the gaps are.

The kit, for buyers in the Netherlands

Dutch-Smart sells Treasure Coast as an XXL grow kit with 2100cc of colonised mycelium, aimed at growers who have done a smaller kit, and as a spore ampoule and spore spray for growers who work sterile. Buying them is legal in the Netherlands for adults; mushrooms that appear from a kit are not. The grow kit page compares the three and has a choice guide.

What makes this cultivar different

Most of what is written about Treasure Coast online repeats the same few lines. The pages here go back to the sources: NOAA's account of the 1715 hurricane, the University of Florida's herbarium labels, the shop's own descriptions, a genome study of commercial cultivars and the Florida statute book. Where a claim cannot be checked, we say so.

  • Name and origin: the 1715 Fleet, the coast and the collector nobody can name.
  • Wild in Florida: 551 records, cattle pastures and the months it fruits.
  • Recognising it: the shop's profile, grower reports and the blue bruise.
  • Grow kit and spores: what is in the box and which to choose.
  • Potency: what is measured for cubensis and what is not for this cultivar.
  • The law: Florida's 2025 spore ban, the 1978 wild mushroom case, the Netherlands, the UK and Germany.
