TEX PE6.

What's known

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

What we actually know

• It is a Psilocybe cubensis, specifically a hobbyist hybrid of a Penis Envy strain crossed with a Texas cubensis. Not a separate species, not a wild-collected strain.
• The whole point of the cross was spore drop: classic Penis Envy is a notoriously poor, slow spore producer, and PE6 was bred to keep PE traits while dropping a usable print.
• The common version is that it deposits a genuinely dark purple-brown print, much more readily than its PE parent. That's why collectors sought it out.
• Morphologically it sits between its parents, more open caps and more proportionate stems than tight PE, while keeping some of PE's chunkiness.
• It is generally dated to the Shroomery-era scene of the late 1990s to early 2000s, though the exact timeline is uncertain and some accounts place the wider Texas PE6 leak considerably later.

What the community says

• The cross is most often credited to a Shroomery user remembered as RogerRabbit, though some accounts name a figure called Workman instead. Treat the attribution as community lore, not settled history.
• RogerRabbit's own telling is wonderfully strange: he is said to have put a PE isolate and a Texas isolate on the same agar plate with rattlesnake venom added, claiming the venom helped the two strains swap genetics into a new sector he labelled PE6. Read this as a colourful origin tale rather than documented method.
• The prints escaped before he was finished, mailed out by accident in a stack of other prints, which is why the strain spread before it was ever formally released.
• Because it carries the Penis Envy name and lineage, it inherits PE's own contested backstory, including the much-repeated Terence McKenna and Steven Pollock Amazonian tale. That lineage myth belongs to PE in general and is unverified.
• Numbered PE spin-offs like PE6 invite the assumption of a tidy PE1 through PE6 series. There is no documented, orderly numbered programme behind the name.

Where it came from

Most famous cubes are loved for how they look or how they grow. TEX PE6 is loved for something much nerdier: it is the Penis Envy strain that you can actually take a print from. Standard Penis Envy is the diva of the cubensis world, a poor and reluctant sporulator with a cap that barely opens, and that scarcity is half its reputation. PE6 is the answer somebody built to that problem.

The common version is that the story starts in the old Shroomery scene somewhere around the late 1990s to early 2000s, when a grower remembered as RogerRabbit set out to cross a Penis Envy isolate with a vigorous Texas cubensis. Some retellings credit a figure called Workman instead, and the dates are fuzzy, so treat the name and timeline as community lore rather than fact. The aim was simple and clever: keep the Penis Envy character, borrow the Texas side's willingness to drop a real spore print.

The headline is that PE6 is the rare Penis Envy relative a collector can study from a normal, heavy, dark print rather than a stingy smear.

What to expect at the scope

RogerRabbit's own account of how he made the cross is one of the better yarns in the hobby. He reportedly described placing a PE isolate and a Texas isolate on the same agar plate with rattlesnake venom added, and claimed the venom somehow helped the two share genetic material into a third sector he named PE6. It is a fantastic story and almost certainly not how the genetics actually worked, so enjoy it as legend. The strain is said to have leaked out before he was finished, apparently mailed by accident among other prints, and it spread from there. What is not in dispute is the end result: a more cubensis-looking, easier-to-print relative of Penis Envy.
