After reading "the six vectors of contamination" In Growing Gourmet & Medicinal Mushrooms (ch 10 P.75) I had some thoughts about vectors of spore dispersal and propagation. My first grow was a Stropharia Rugosoannulata (garden giant) indoor mushroom kit, I had many troubles and eventually broke up the kit and made a patch outside that had a few cycles of fruiting. Slugs were attracted to the mushrooms and destroyed some before they had a chance to sporulate. I did not want to interfere with the natural order by killing or preventing the slugs access to the mushroom patch, I had this gut feeling that slugs may be valuable to mushrooms as vectors of spore dispersal and eventually found at least one article to back up my "feeling". (Such as spores attached to their bodies or passing through their digestive system unharmed ect) http://www.fungimag.com/summer 2010 articles/Slugs & Mushrooms.pdf The other thought is that as they travel thought a mushroom patch it would be possible for tiny fragments of mycelium to attach to their bodies and be carried to a new location. Through less controls is it possible to aid in the creation of a hardier feral strain? How long can spores lie dormant in soil? If you introduce mycelium from a species that is non native to your area and would not fruit outdoors, is it possible for the mycelium to continue vegetative growth? I am by no means a mycologist, more of a wannabe but I have lots of questions and if anybody has answers I would be happy to read them. I apologize if my questions are childish or ignorant. Dang after the post I noticed the experimental mycology forum, maybe it was better suited there?
