Psylocybe Fanaticus.

What's known

Here's what's meant to be true and not.

What we actually know

• It was distributed by Robert 'Billy' McPherson under the alias Psylocybe Fanaticus, the deliberate misspelling he reportedly kept once the name had stuck.
• It dates to the early 1990s and circulated alongside McPherson's PF Tek, the brown-rice-flour-and-vermiculite method that became one of the most widely copied home-cultivation guides ever published.
• Genetically it is a plain Psilocybe cubensis. Not a hybrid and not a separate species.
• It drops a clean, heavy, dark purplish-brown spore print and is regarded as a reliable depositor, which is one reason it spread so widely.
• By most accounts it is a notably late depositor, releasing spores only once the cap has fully opened, so a heavy print tends to come from a mature specimen rather than a young one.
• It is NOT the PF Redspore: that pale rusty-spored strain was a separate mutation reportedly seen in McPherson's lab around 1996, not PF Classic itself.

What the community says

• The 'PF' is said to stand for Psilocybe Fanaticus, McPherson's chosen handle, though he wrote it 'Psylocybe' with a y and the story goes he simply never corrected it.
• It is often called the original beginner's strain, selected to behave predictably alongside the PF Tek, which is said to be where the 'Classic' tag came from.
• Community lore credits PF Classic with helping kick off the mail-order spore-syringe scene of the 1990s, for better and worse given how that story ended in court.
• Some sellers blur PF Classic together with the redspore variant or with later 'PF' rebrands. The dark-spored Classic is the original strain and the others are offshoots.

Where it came from

Most cubensis strains arrive with a fog of rumour and no documents. PF Classic is the rare exception, because the man behind it left a record you can actually follow. By most accounts the strain traces to Robert "Billy" McPherson, who traded under the deliberately misspelled name Psylocybe Fanaticus and, in the early 1990s, published the PF Tek, the brown-rice-flour and vermiculite method that went on to be copied, printed and passed around more times than anyone could reasonably count.

PF Classic was the strain that circulated alongside that method, and the pairing of a famous technique with a famous name is, the story goes, a large part of why it spread so far. It became, for many people, the first cube they ever read about.

PF Classic is one of the few cubensis strains whose origin you can name, date and footnote rather than guess at. The history is the appeal as much as the mushroom is.

What to expect at the scope

The part of the legend is also the sad part. McPherson was raided in 2003, and his collection of cubensis genotypes was, by most accounts, seized and destroyed in the process. He later died in 2011. What survived him was the technique and the strain that carried his alias out into the world, both of which long outlasted the man. Treat the courtroom and biographical details as the documented record they are, and the rest, the "Classic" branding and the beginner-strain framing, as the community lore it has become. One thing worth keeping straight: PF Classic is the dark-spored original, while the pale, rusty-spored oddity people remember is the separate PF Redspore, reportedly a mutation that turned up around 1996. The two get muddled constantly. If your print is a clean purple-brown, you have the Classic.
