Blue Vootwo: the A.C.S isolation of Blue Voodoo
Blue Vootwo has the most completely documented pedigree of any card in this chapter: an American isolation of an Australian cross, with both breeders named and both parents on record. That makes it the best specimen here for studying what isolation actually does.
01What Blue Vootwo is
Blue Vootwo is an isolated Psilocybe cubensis line, catalogued in full as BLUE VOOTWO (ACS Blue voodoo iso). It is the A.C.S isolation taken from Blue Voodoo, and the listing credits the original cross to Q of What The Fungi. The card carries the A.C.S crest because the isolation is their work, while the cross underneath it is his.
02Lineage and history
The pedigree runs three deep and every step is on record:
- Blue Ravioli, a Psilocybe cubensis line from the early 2020s, named for its blue-toned, folded cap. Its own parentage is not well documented, so the library treats it as a named line rather than a cross.
- Natal Moon, a cross of the Ochra species with Phobos, credited to Jeff Karas of The Fungus Frequency.
- Blue Voodoo (Blue Ravioli x Natal Moon), Q's What The Fungi cross of the two, which makes it an interspecies hybrid.
- Blue Vootwo, the A.C.S isolate selected out of Blue Voodoo and stabilised under its own name.
Because Natal Moon sits on one side, Blue Vootwo carries Ochra as well as cubensis in its ancestry. The wider family, including Gamma Decay and Auric Stew, is mapped in Blue Ravioli and its crosses, and every link is drawn on the lineage explorer.

03Under the microscope
This is the card to buy if you want to see what an isolate is. Blue Voodoo, the cross, carries the breadth of two parents and is described by its breeder as throwing several distinct phenotypes. Blue Vootwo is one of those expressions, selected and worked until it comes true. On the measurement sheet that shows as a tighter spore size range from the isolate than from the cross.
Expect a pigmented cubensis spore: subellipsoid, thick-walled, germ pore, purple-brown. The blue colouring the family is named for belongs to the fruiting body and will not appear on your slide. What may appear, in the print, is the Ochra grandparent: deposits from this family can run a shade lighter and browner than a straight cubensis print.

Questions people ask
What is Blue Vootwo a cross of?
It is not a cross, it is an isolate. Blue Vootwo is the A.C.S selection from Blue Voodoo, which is the What The Fungi cross of Blue Ravioli and Natal Moon.
Who bred Blue Vootwo?
A.C.S did the isolation; Q of What The Fungi made the Blue Voodoo cross it came from. The card credits both.
Can I buy this strain legally in the UK?
Spores contain no controlled substance and are sold for microscopy, taxonomy and research. Germinating them is an offence in the UK, which is why every specimen here is supplied strictly for microscopy. See our Legal Use Policy. This is not legal advice.
