Q: can two fungal species mate and reproduce new species?

Among plants, interspecific hybridization is certainly common. Modern
wheat, which is a hybrid of three different "primitive" wheat species, is
a well-known example. Smoking tobacco, which is a hybrid of two ancestral
tobacco species is another. There are many other examples.
For a couple of examples from the fungal world see Ersek et al
Phytopathology, 85, 1343-1347,1995 and references therein. I am sure there
are other examples too, though I doubt that a systematic study of the
limitations has been conducted.
As to whether an interspecies hybrid constitutes a new species, it depends
on your definition of a species.
