Yes, definitely, Steve. Thermal death limits of psilocybe cubensis mycelium has been established at 106 degrees fahrenheit, according to the literature.
Dried, dormant spores are certainly more resistant to environmental extremes than mycelium, which is why a spore print will last so long. But the spores in a syringe are not dried and dormant, they are fully hydrated and ready to germinate the instant they find the proper nutrients. Not only that, but they are surrounded by water, not by air. We all know from experience that stepping into a bath of 95 degrees feels a lot warmer than standing in air of 95 degrees.
The spores were weakened by their exposure to high temperatures to the point where they failed to germinate, even if they were not yet technically "dead". A spore syringe may survive a brief exposure to high temperatures during shipping, but it cannot be stored at such high temperatures.
On the bright side, at least you know that there was nothing wrong with the preparation of your jars. The lack of contaminants proved you would have had success with viable spores.
The reputable supplier in Holland... was it Una's company, MushMush.nl?
