Hell Monkey is a modern Psilocybe cubensis isolate from the hobby breeding scene, sold under the one name by a limited number of vendors. Its pedigree has not been published; where a listing gives parents, that is the vendor's own account and should be read that way. The name is a breeder's invention and does not refer to a collection site.
The listing should say whether the line is pigmented or pale, which tells you whether to expect a purple-brown print or a faint one. Spores are subellipsoid, in the usual cubensis range of around 11 to 17 by 7 to 10 micrometres. Hell Monkey is sold as isolate syringes and swabs, so look for the isolate name and the generation.
Every Hell Monkey listing above comes from an independent vendor who prepared it, and the vendor's country, shipping regions and real customer reviews are on their store page. Labels tell you what you are getting: a multispore syringe carries many genetic individuals, an isolate (ISO) is a single worked line, and prints and swabs are the dry, long-life formats. Isolated vs multispore syringes explains the difference, how to store spore syringes covers shelf life, and how to use a spore syringe for microscopy walks through the slide. Buying in the UK?
