If Workman is correct with the virus theory...then chances are all this will be for not.
however, on the bright side, all these years we've been witness to an epic struggle between two lifeforms. If this be the case, then I wonder if the increase in first flush fruiting yields is a reaction of the mushroom to the virus. Kind of a "if you aren't gonna let me sporulate normally then I'll just shit out more fruits" type of attitude. Of course, the mushroom is not a calculative creature and the response would be instinctual, but it makes me wonder......
