^ Drugs are bad mkay. I do it for the exercise, food, quick money, and travel. I'm really only at peace out in the woods or on the shore or in the pines. Been a horrible fall 2016 and spring 2017, but likely just means we get a bumper crop this year. Usually rotates that way.
TwoTokes - there are dozens species with "purple stripes" that grow in abundance. Perhaps you mean blue staining on fruitbodies from the oxidation of psilocybin into psilocin as it is exposed to heat water and air. You can accelerate the process using KaOH, or just know which ones to look for. If you run a fingernail across a stem and it doesn't bruise blue in fifteen minutes you've got the wrong ones.
Out here we have psilocybe ovoideocystidiata, psilocybe cyanescens, panaelous cyanescens, psilocybe semilanceata, psilocybe azurescens, panaelous cinctulus, psilocybe allenii, a wide variety of gymnopilus and a bunch of non-native psilocybes and some panaeolus that are being introduced by growers and people who establish patches.. alutecea, ps serbica.. bunch of European and Australian species as well as weilii and a couple others.
So purple streaks means nothing be careful what you eat folks
for dinner or for fun.
