Australian, or Aussie, is a Psilocybe cubensis name covering collections from Australia, where the species grows on cattle dung in the subtropical east. The fruit is usually described as having orange to golden caps. Several distinct collections are sold under the name, so one vendor's Aussie may differ from another's.
It is a standard cubensis for microscopy: purple-brown print, subellipsoid spores around 11 to 17 by 7 to 10 micrometres, sold as multispore syringes and prints. Note that Australian spore law differs by state and territory, and in some of them the sale or possession of Psilocybe spores is restricted, so buyers in Australia need to check their own state's position before ordering.
Every Australian 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? Read are mushroom spores legal in the UK. In the United States, see the state by state guide.
