Texas is a Psilocybe cubensis strain said to come from a wild collection in the state, where the species grows on cattle dung through the warm months. The name has been used for several distinct collections over the years, and sub-lines such as Texas Orange Cap and Texas Yellow Cap are sold separately, so one vendor's Texas may not match another's.
As a wild-derived multispore it shows the usual cubensis traits under the microscope: a purple-brown print and subellipsoid spores about 11 to 17 by 7 to 10 micrometres. It is sold mostly as multispore syringes and prints. The label should name the sub-line where there is one, and the generation if the vendor tracks it.
Every Texas 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?
