"...this same smut (TB), or a species indistinguishable from it (T. pulcherrima) (TP) causes smut of several widespread native grasses. Because of this, there is a potential for KB false positives from smut on these grasses."

The presence of a TI
look-alike known as T. pulcherrima on some native grasses
emphasizes the need to be absolutely sure of ones identification.
This would ideally be done using genetic testing. However, as I
understand it, this requires a viable spore. I wonder what one
would do if they recovered a non-viable spore matching the
description of TI? Do other labs have a protocol for such a
situation? I'm especially thinking of labs dealing with grain
from what are presently considered KB free areas.
