Sometimes there are blackish rye kernels among the normal ones, but it could also be ergot sclerotia, sometimes found in biologicaly grown grains.

Ergot, caused by the fungus Claviceps purpurea, attacks morethan 200 grass hosts as well as cultivated cereals throughout the world. Ergot is most prevalent on rye but occurs to some extent each year in Iowa on barley, oats, and wheat as well as wild and cultivated grasses.Reference to ergotism dates back to Biblical time. Records show ergot has caused serious disease epidemics of plantsand animals, including man. Ergot is not as important in reducing yields of grain as it is in poisoning animals and man. Also of importance are medicinal properties of extracts madefrom ergot bodies or sclerotia. Sufficient quantities of ergot make feed unsafe for livestock. In the commercial grain trade, grain is classed as "ergoty"when it contains more than 0.3 percent by weight of ergotsclerotia.
Ergot contains toxic alkaloids which cause ergot poisoning in animals. The alkaloids in ergot may vary in quantity and quality within a growing season or from year to year. Alkaloids will also vary with different grains. Because of this variation, sclerotia will vary from low to high toxicity. Generally the concentration of alkaloids in sclerotia increases with grain maturity. Ergotism occurs in animals that are fed grain containing high levels of ergot sclerotia over an extended period of time. The toxicity of ergoty grain varies with the species and type ofanimal. In general, grain containing more than 0.5 percentergot should be fed with extreme caution, and levels greater than 1.0 percent can be expected to cause problems.The alkaloids from infested sclerotia cause contraction of the small blood vessels. Eventually the blood supply is shut off or reduced to the body appendages such as legs, ears, and tail. The surrounding tissue is deprived of nutrients and oxygen and the tissue begins to die. This condition is morenoticeable during cold weather. The damage resembles that caused by frostbite or freezing of the extremities.
In a pregnant animal, some of the alkaloids may activate con-traction of the uterine muscles, resulting in abortion of the fetus. Although all alkaloids found in ergot affect small blood vessels and uterine muscles, some may have a greater effecton one than the other. Ergot in grain may cause a decrease of milk production in lactating sows with loss of pigs from starvation. Occasionally alkaloids affect the nervous system with rapid onset of convulsions and hallucinations.
No ergot-resistant commercial cereal varieties have been developed, but the following measures will help control er-got-* Because ergot sclerotia do not remain viable for more thanone year in soil, rotation to a nongrass will reduce ergot incidence.

Anybody ever read the book (can't remember the title) that claims the salom witch trials were a direct result of ergot contaminated rye used to bake bread? The symptoms from ergotamine poisoning are identical to the symptoms that the "possessed" witches were showing. The author was even able to show which field the contaminated rye came from.

It sounds like you should be fine. Even if the black is ergot, your boiling/PCing should have killed it off. As long as the mycelium continues to look healthy I wouldn't worry.
