B+ Spores: Syringes, Prints & Isolates

B+ is one of the most widely sold Psilocybe cubensis multispore strains, known for large caramel coloured caps. The usual story is that it was isolated by a Florida grower in the 1990s, and an older claim that it was a cubensis and azurescens hybrid is not supported, since the two species cannot cross. Treat the origin as folkloric.

Under the microscope it is a textbook cubensis: dense purple-brown print, subellipsoid spores around 11 to 17 by 7 to 10 micrometres, which makes it a good first comparison slide. Because B+ has been reproduced from multispore for so long, lines vary between vendors. It is sold as multispore syringes and prints, and is one parent of Tidal Wave.

Buying B+ spores for microscopy

Every B+ 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.
