Ok, damn I wish I got paid for this.
There are many fungi in the Hypocreaceae family that produce the interesting lysergic acid amides alkaloids (LSAs, ergolines.) These alkaloids are found in many genuses of Hypocreaceae. The most common are in the ergot genus, and this includes the well-known species
Claviceps purpurea and
Claviceps paspali. Some of these same alkaloids are found outside of the Hypocreaceae family. They are also found in the higher plant-family, Convolvulaceae, which includes the morning glory family.
According to A. Hoffmann (inventor of LSD) who said in his book
"The Road to Eleusis: Unveiling the Secret of the Mysteries" that, "Ergoline alkaloids more or less fall into two categories: non-water soluble peptide alkaloids, which exert more toxic effects, and water soluble lysergic acid derivatives with psychedelic effects more pronounced."
Claviceps purpurea is known to produce these toxic ergopeptide compounds that cause the syndrome known as "St. Anthony's Fire" or ergot poisoning. Ergocristine, ergocryptine and Beta-ergocryptine are three that come to mind, but there are many others I don't remember off my head. These chemicals are intensely toxic and the poisoning can not be often be reversed often once it has really taken hold. The stories of arms falling off from ergot are no joke.
Another species of ergot,
Claviceps paspali does not produce these toxic ergopeptides, but instead only produces the psychedelic lysergic acid amides also found in some morning glory seeds. It is this species of ergot that the ancient psychedelic of Greece, "kykeon", was made from.
Neither kykeon, nor any species of morning glory has ever caused ergotism because neither contain the toxic ergopeptides.
Seriously, I wish people would do more research before spreading silly rumors like "morning glory can cause ergotism in high dosages", or insinuating they can because that obviously indicates that one does not have any idea what causes ergot poisoning in the first place. The chemicals in morning glory seeds do not cause ergot poisoning.
One doesn't need to ask Erowid or anyone else. This research on ergot has been going on since the 1930s and simply reading a few books and journals would tell you all these things I am. One should read them before assuming what causes ergot poisoning is what is in morning glory seeds. It isn't and this is how crazy rumors like "LSD will make your spine bleed" get started.
