El Toque f2 (El Choco x Toque f8): reading a pedigree in full
El Toque f2 (El Choco x Toque f8) is the most information-dense name in the library. Two parents, two generation counts and a named breeder, all in one line. Once you can read it, you can read any card on the site.
01What El Toque f2 is
El Toque f2 is an isolated Psilocybe cubensis cross, catalogued in full as El Toque f2 (El Choco x Toque f8), with the original cross credited to ClusterDuckMycology. It reaches the library through the A.C.S and Mushrealm side of the collection.
02Lineage and history
Take the name apart and the whole history falls out:
- El Choco and Toque are the two parent lines. The x means the line was bred from them, not that two things are mixed in the syringe.
- f8 on the Toque parent counts generations: that side had already been taken through eight rounds of selection before the cross was made, which usually means a settled, predictable parent.
- f2 on the front is the generation of the resulting line. This is the second generation from the cross, not the first.
- ClusterDuckMycology is the breeder credited with making the original cross.
The library carries two more Toque cards, Green Toque and Toque x Jack Frost, so the parent line can be studied on its own and in a second, quite different cross. Our full decoder is in how to read a strain name.
Lineage does not change what a cubensis spore is; it changes the range you measure.
03Under the microscope
Expect a pigmented cubensis population: subellipsoid, thick-walled, germ pore, purple-brown in mass, with a dense and even print. Nothing about the pedigree changes the basic morphology, which is the point worth internalising. Lineage does not change what a cubensis spore is; it changes the range you measure and the deposit you get.
The interesting exercise here is generational. An f2 from a cross with an f8 parent should measure more tightly than a fresh f1 from two unworked lines, because most of the variation on the Toque side has already been selected out. That is a claim you can test with a graticule and twenty spores.
04Where to buy El Toque f2 in the UK
El Toque f2 is in stock now. The card is El Toque f2 spore syringe in the strain library. Every syringe is a 10 ml luer-lock, filled in a flow hood from a logged print into sterile water, capped, labelled with the strain and its LOT, and refrigerated until it is packed.
- Price: isolated lines are listed at £20 per syringe. The card shows the current price, including any sale.
- UK shipping: £3.80, and free on orders over £75. US orders ship at a flat $8.

- Every order is 18+ and confirms lawful microscopy use at checkout.
Browse the rest of the collection on the Mushrealm and A.C.S chapter, or open the strain library to filter by species, format or isolation status. If anything arrives cloudy or damaged, email a photo and the LOT number and it is replaced.
Specimens for this story: GREEN TOQUE, Toque x Jack Frost and DreadMaw (Gamma Decay iso), all prepared under sterile protocol and LOT-logged in the UK.
Questions people ask
What does f2 mean in El Toque f2?
The second generation from the original cross. The f8 on the Toque parent means that side had already been through eight generations before the cross was made.
Who made El Toque f2?
ClusterDuckMycology. The original cross is credited to them on the card.
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.
