I doubt this: as long as there are scientists, who have a need to know that
species they are dealing with, there will be some classification to sort the
different species into.
And naturally there will have to be some "concept" to distinguish between
some morph or genet being a species or belonging to a subspecies, forma
specialis or whatever.

I can follow you to they point that the current concepts are not easily
applicable to fungi. But the difficulties do not pose into question the
concepts themselves.

What do you try to say, I do not get your meaning here.
Molecular biology and current morphology-based systematic are not congruent,
investigations into the genetic structure and diversity of species and their
populations show that we still do not grasp the inherent complexities of
fungal lifestyles.

That also shows that we have a problem with regard to the _application_ of
our current species concepts and the methods to distinguish between the
species.
To fully "understand" a species you have to take into account its genetic
structure and built, its morphology, life cycle, the ecology. When you take
these all together, an idea about the species´ "identity" arises. But only
then.

No single road will lead to the goal: neither molecular biology, nor
morphology.
