Hello!
Bumped into this - science with human face
https://blog.mycology.cornell.edu/2010/06/02/a-fungus-walks-into-a-singles-bar/
EDIT:
I found info here of both cubes and semilanceatas having tetrapolar mating system.

Blakeslee’s studies in the Mucorales showed that in those Zygomycetes that are heterothallic the single-spore cultures are either + or - as far as mating is concerned. However, things are more complicated in the Basidiomycetes. The genetic basis of this pattern of sexuality, known as tetrapolarity, was first most completely described by Kniep, who pointed out the involvement of two mating type factors (A and B), with heterozygosity at both loci required for the formation of the clamped (dikaryotic) mycelium. Thus, the spores arising from the basidia following meiosis are of four types, in terms of mating type...
...In the intervening years between the original studies of Bensaude and Kniep and the early 1950s, much additional information was learned about sexuality in the Basidiomycetes:
1. The finding that each of the mating type loci contained a series of multiple alleles. This was later investigated more thoroughly by Raper and coworkers,33 who have shown that each of the mating type “loci” consists of a chromosomal segment with subunits of the factors within which crossing-over takes place.
2. In some heterothallic species there is only one mating type locus (such species are referred to as “bipolar”), but multiple alleles exist here also.
3. In addition, there are homothallic species as those in which mycelium arising from a single spore can complete the life cycle.

Yep, normally its a heterothallic species with 4 haploid spores on each basidia. Homothallism could probably be induced under the right conditions and theres also the buller phenomenon causing di-mon mating to consider when talking about genetics.
Heres an interesting debate on breeding through anastomosis:
