These are the spores from an F1 (1st filial generation) cross from a dikaryon and monokaryon cultures. The resultant dikaryon was fruited using traditional CV substrate and the fruit were swabbed. There are two swabs in a set. Each swab contains thousands of spores which can be used to create the next generation, perform phenohunting, and produce unique strains and new types of mushrooms.
This is a di-mon cross using a dikaryon blob Rusty Whyte and a monokaryon (Toque) agar culture. The RW dikaryon donates one of the nuclei to the Toque monokaryon, thus forming a new genetic combination which is capable of producing normal fruits and spores.
Here is a video showing how it was done using my monokaryon liquid culture shot directly into a grain spawn bag. Same basic idea with an agar piece.
