Hellmonkey (Hellhound x SpaceMonkey): a documented A.C.S cross
Hellmonkey is a portmanteau of its two parents, which is the oldest naming convention in the hobby and the most useful one. The card tells you the cross, the original breeder and who worked it since.
01What Hellmonkey is
Hellmonkey is an isolated Psilocybe cubensis line catalogued as Hellmonkey (Hellhound x SpaceMonkey), with the original cross credited to Maniacal Mycology. It is part of the A.C.S collection the library carries through Mushrealm, and the listing says so explicitly so that buyers can tell A.C.S work from everything else.
02Lineage and history
The name is the pedigree: Hellhound crossed with Spacemonkey. Both parents are American hobby-bred cubensis lines, and as with most lines that spread by trade rather than publication, their own parentage is not formally documented. The library records what is on the card and no more.
What is documented is the chain of custody: Maniacal Mycology made the cross, A.C.S worked and isolated it, Mushrealm carries the collection, and MycoWorld prepares the syringes in the UK. That chain is the reason a name like Hellmonkey means something rather than being decoration. Our guide to the A.C.S and Mushrealm lines explains how the collection is organised.

A portmanteau name is a claim about parentage.
03Under the microscope
Hellmonkey is a pigmented cubensis, so the slide is a standard one: subellipsoid, thick-walled spores in the 11 to 17 micrometre range, a clear germ pore at 1000x, purple-brown in mass, and a dense print. Our cubensis spore morphology guide is the reference description.
Because it carries the ISO tag it should measure tightly, and because it is a cross of two named lines it is a good candidate for a three-slide study if you can source either parent: parent, parent, offspring, same objective, same light, twenty spores each.

04Where to buy Hellmonkey in the UK
Hellmonkey is in stock now. The card is Hellmonkey 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.
- Dispatch: one to two working days from the UK, tracked, in a plain padded mailer with no branding on the outside.
- 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: Lucid Gates, Project Bluebook (CG isolation) and DreadMaw (Gamma Decay iso), all prepared under sterile protocol and LOT-logged in the UK.
Questions people ask
What is Hellmonkey a cross of?
Hellhound and SpaceMonkey. The listing credits the original cross to Maniacal Mycology.
Is Hellmonkey an A.C.S line?
The cross is Maniacal Mycology's; A.C.S worked and isolated it, and the library carries it in the A.C.S collection through Mushrealm.
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.
